The pagerev.php script was refactored into separate functions to allow easier integration of recipes displaying the page history.

A couple of minor bugs were fixed and the documentation was updated.

Version 2.2.9, 2.2.10 (2010-01-17)

Most important in this release is the official change of $EnableRelativePageVars to 1. The change is about how {$Variable} in included pages is understood by Pm Wiki.

• When $EnableRelativePageVars is set to 0, {$Name} displays the name of the currently browsed page. Even if {$Name} is in an included page, it will display the name of the browsed page.
• When $EnableRelativePageVars is set to 1, {$Name} displays the name of the physical page where it written. If {$Name} is in an included page, it will display the name of the included page.
• {*$Name} always displays the name of the currently browsed page, regardless of $EnableRelativePageVars.

So, if your wiki relies on page variables from included pages, and doesn't have $EnableRelativePageVars set to 1, after upgrading to 2.2.9, you can revert to the previous behavior by adding to config.php such a line:

  $EnableRelativePageVars = 0;

More information about page variables can be found at:

  http://www.pmwiki.org/wiki/PmWiki/PageVariables

This release adds a new variable $EnablePageTitlePriority which defines how to treat multiple (:title..:) directives. If set to 1, the first title directive will be used, and if a page defines a title, directives from included pages cannot override it. Pm Wiki default is 0, for years, the last title directive was used (it could come from an included page or Group Footer).

This release also adds a new variable $DiffKeepNum, specifying the minimum number (default 20) of edits that will be kept even if some of them are older than the limit of $DiffKeepDays.

A number of bugs were fixed and the documentation was updated.

Version 2.2.8 (2009-12-07)

This release fixes another PHP 5.3 compatibility issue with conditional markup. The Author field now handles apostrophes correctly. The documentation was updated.

Version 2.2.7 (2009-11-08)

This release fixes most PHP 5.3 compatibility issues. Unfortunately some specific builds for Windows may still have problems, which are unrelated to Pm Wiki. Notably, on Windows, all passwords need to be 4 characters or longer.

Upload names with spaces are now correctly quoted. The documentation was updated.

Version 2.2.6 (2009-10-04)

With this release it is now possible to display recently uploaded files to the Recent Changes pages -- if you have been using the Recent Uploads Log? recipe, please uninstall it and follow the instructions at http://www.pmwiki.org/wiki/Cookbook/RecentUploadsLog.

The release also introduces $MakeUploadNamePatterns to allow custom filename normalization for attachements. It is now possible to replace $PageListFilters and $FPLTemplateFunctions with custom functions. Notify should now work in safe_mode. Some bugs were fixed, among which one with conditional markup with dates. The documentation was updated.

Version 2.2.5 (2009-08-25)

This release adds a new markup for Pagelist templates, (:template none:) which allows a message to be set when the search found no pages. The FPL Template?() function was broken into configurable sub-parts to allow development hooks. A number of bugs were fixed, and the documentation was updated.

Version 2.2.4 (2009-07-16)

This release fixes a bug introduced earlier today with HTML entities in XL Pages?.

Version 2.2.3 (2009-07-16)

This release fixes six potential XSS vulnerabilities, reported by Michael Engelke. The vulnerabilities may affect wikis open for editing and may allow the injection of external Java Scripts? in their pages. Public open wikis should upgrade.

A new variable $EnableUploadGroupAuth was added; if set to 1, it allows password-protected uploads to be checked against the Group password.

It is now possible to use @_site_edit, @_site_read, @_site_admin or @_site_upload global passwords in Group Attributes? pages.

A number of other small bugs were fixed, and the documentation was updated.

Version 2.2.2 (2009-06-21)

The major news in this release is a fix of an Auth User vulnerability.

The vulnerability affects only wikis that (1) rely on the Auth User core module
for User:Password authentication, -AND- (2) where the PHP installation runs
with the variable "magic_quotes_gpc" disabled.

All Pm Wiki 2.1.x versions from pmwiki-2.1.beta6 on, all 2.2.betaX, 2.2.0, and
2.2.1 are affected.

The Pm Wiki SiteAnalyzer? can detect if your wiki needs to upgrade:

  http://www.pmwiki.org/wiki/PmWiki/SiteAnalyzer

If your wiki is vulnerable, you should do one of the following at the earliest
opportunity:

• Upgrade to a version of Pm Wiki at least 2.2.2 or greater.
• Turn on magic_quotes_gpc in the php.ini file or in a .htaccess file.

Alternatively, you can temporarily disable Auth User until you upgrade.

Note that even if your wiki does not have the Auth User vulnerability at the
moment, you are strongly encouraged to upgrade to Pm Wiki version 2.2.2 or
later, as some future configuration of your hosting server might put you at
risk.

This release also comes with minor updates in the local documentation; fixes
were applied for international wikis - notably global variables in
xlpage-utf-8.php and a new variable $EnableNotifySubjectEncode, which allows
e-mail clients to correctly display the Subject header; and a number of other
small bugs were fixed.

Version 2.2.1 (2009-03-28)

This release comes with an updated local documentation; wiki trails now work cross-group; guiedit.php now produces valid HTML, and other small bugs were fixed. We also added $EnableRedirectQuiet, which allows redirects to take place without any mention of "redirected from page ....".

Version 2.2.0 (2009-01-18)

This is a summary of changes from 2.1.x to 2.2.0.

• Several pages that were formerly in the Site.* group are now in a separate SiteAdmin.* group, which is read-restricted by default. The affected pages include Site.Auth User, Site.Auth List?, Site.Notify List, Site.Blocklist, and Site.Approved Urls? . If upgrading from an earlier version of Pm Wiki, Pm Wiki will prompt to automatically copy these pages to their new location if needed. If a site wishes to continue using the old Site.* group for these pages, simply set

• Important Change in Passwords in Pm Wiki 2.2 indicating that the group can be edited even if a site password is set will be done by "@nopass" prior it was done by "nopass"

• Pm Wiki now ships with Wiki Words entirely disabled by default. To re-enable them, set either $LinkWikiWords or $EnableWikiWords to 1. To get the 2.1 behavior where Wiki Words are spaced and parsed but don't form links, use the following:

• It's now easy to disable the rule that causes lines with leading spaces to be treated as preformatted text -- simply set $EnableWSPre=0; to disable this rule.
  Important: There is ongoing discussion that the leading whitespace rule may be disabled by default in a future versions of Pm Wiki. If you want to make sure that the rule will continue to work in future upgrades, set $EnableWSPre=1; in local/config.php.
• The $ROSPatterns variable has changed somewhat -- replacement strings are no longer automatically passed through Fmt Page Name() prior to substitution (i.e., it must now be done explicitly).
• Page variables and page links inside of (:include:) pages are now treated as relative to the included page, instead of the currently browsed page. In short, the idea is that links and page variables should be evaluated with respect to the page in which they are written, as opposed to the page in which they appear. This seems to be more in line with what authors expect. There are a number of important ramifications of this change:

• We now have a new {*$var} form of page variable, which always refers to "the currently displayed page". Pages such as Site.Page Actions and Site.Edit Form that are designed to work on "the currently browsed page" should generally switch to using {*$FullName} instead of {$FullName}.
• The $EnableRelativePageLinks and $EnableRelativePageVars settings control the treatment of links and page variables in included pages. However, to minimize disruption to existing sites, $EnableRelativePageVars defaults to disabled. This will give existing sites an opportunity to convert any absolute {$var} references to be {*$var} instead.
• Eventually $EnableRelativePageVars will be enabled by default, so we highly recommend setting $EnableRelativePageVars = 1; in local/config.php to see how a site will react to the new interpretation. Administrators should especially check any customized versions of the following:
  Site.PageActions
  Site.EditForm
  Site.PageNotFound
  Side Bar? pages with ?action= links for the current page
  $GroupHeaderFmt, $GroupFooterFmt
  Page lists that refer to the current group or page, etc in sidebars, headers, and footers
• The (:include:) directive now has a basepage= option whereby an author can explicitly specify the page upon which relative links and page variables should be based. If no basepage= option is specified, the included page is assumed to be the base.

• Sites that want to retain the pre-2.2 behavior of (:include:) and other items can set $Transition['version'] = 2001900; to automatically retain the 2.1.x defaults.
• Text inserted via (:include:) can contain "immediate substitutions" of the form {$$option} -- these are substituted with the value of any options provided to the include directive.
• Pm Wiki now recognizes when it is being accessed via "https:" and switches its internal links appropriately. This can be overridden by explicitly setting $ScriptUrl and $PubDirUrl.
• A new $EnableLinkPageRelative option allows Pm Wiki to generate relative urls for page links instead of absolute urls.
• Draft handling capabilities have been greatly improved. When $EnableDrafts is set, then the "Save" button is relabeled to "Publish" and a "Save draft" button appears. In addition, an $EnablePublishAttr configuration variable adds a new "publish" authorization level to distinguish editing from publishing. See PmWiki:Drafts for more details.

• There is a new {$:var} "page text variable" available that is able to grab text excerpts out of markup content. For example, {SomePage$:Xyz} will be replaced by a definition of "Xyz" in Some Page?. Page text variables can be defined using definition markup, a line beginning with the variable name and a colon, or a special directive form (that doesn't display anything on output):

  :Xyz: some value            # definition list form
  Xyz: some value             # colon form
  (:Xyz: some value:)         # directive form
  

• The (:pagelist:) command can now filter pages based on the contents of page variables and/or page text variables. For example, the following directive displays only those pages that have an "Xyz" page text variable with "some value":
  (:pagelist $:Xyz="some value":)
  
  Wildcards also work here, thus the following pagelist command lists pages where the page's title starts with the letter "a":
  (:pagelist $Title=A* :)
• The if= option to (:pagelist) can be used to filter pages based on conditional markup:
  (:pagelist if="auth upload {=$FullName}":) pages with upload permission
  (:pagelist if="date today.. {=$Name}":) pages with names that are dates later than today
• Spaces no longer separate wildcard patterns -- use commas. (Most people have been doing this already.)
• Because page variables are now "relative", the {$PageCount}, {$GroupCount}, {$GroupPageCount} variables used in pagelist templates are now {$$PageCount}, {$$GroupCount}, {$$GroupPageCount}.
• One can now use {$$option} in a pagelist template to obtain the value of any 'option=' provided to the (:pagelist:) command.
• The (:pagelist:) directive no longer accepts parameters from urls or forms by default. In order to have it accept such parameters (which was the default in 2.1 and earlier), add a request=1 option to the (:pagelist:) directive.
• The count= option to pagelists now accepts negative values to count from the end of the list. Thus count=5 returns the the first five pages in the list, and count=-5 returns the last five pages in the list. In addition, ranges of pages may be specified, as in count=10..19 or count=-10..-5.
• Pagelist templates may have special (:template first ...:) and (:template last ...:) sections to specify output for the first or last page in the list or a group. There's also a (:template defaults ...:) to allow a template to specify default options.
• Pm Wiki comes with an ability to cache the results of certain (:pagelist:) directives, to speed up processing on subsequent visits to the page. To enable this feature, set $PageListCacheDir to the name of a writable directory (e.g., work.d/).
• The (:if ...:) conditional markup now also understands (:elseif ...:) and (:else:). In addition, markup can nest conditionals by placing digits after if/elseif/else, as in (:if1 ...), (:elseif1 ...:), (:else1:), etc.
• The (:if date ...:) conditional markup can now perform date comparisons for dates other than the current date and time.
• WikiTrails can now specify #anchor identifiers to use only sections of pages as a trail.
• A new (:if ontrail ...:) condition allows testing if a page is listed on a trail.
• The extensions .odt, .ods, and .odp (from Open Office?.org) are now recognized as valid attachment types by default.
• A new blocklist capability has been added to the core distribution. It allows blocking of posts based on IP address, phrase, or regular expression, and can also make use of publicly available standard blocklists. See PmWiki.Blocklist for details.
• There is a new SiteAdmin.AuthList page that can display a summary of all password and permissions settings for pages on a site. This page is restricted to administrators by default.
• There are new {$PasswdRead}, {$PasswdEdit}, etc. variables that display the current password settings for a page (assuming the browser has attr permissions or whatever permissions are set in $PasswdVarAuth).
• Forms creation via the (:input:) markup has been internally refactored somewhat (and may still undergo some changes prior to 2.2.0 release). The new (:input select ...:) markup can be used to create select boxes, and (:input default ...:) can be used to set default control values, including for radio buttons and checkboxes.
• The (:input textarea:) markup now can take values from other sources, including page text variables from other pages.
• Specifying focus=1 on an (:input:) control causes that control to receive the input focus when a page is loaded. If a page has multiple controls requesting the focus, then the first control with the lowest value of focus= "wins".
• Pm Wiki now provides a scripts/creole.php module to enable Creole standard markup. To enable this, add include_once('scripts/creole.php') to a local customization file.
• Pm Wiki adds a new {(...)} markup expression capability, which allows various simple string and data processing (e.g., formatting of dates and times). This is extensible so that recipe authors and system administrators can easily add custom expression operators.
• It's now possible to configure Pm Wiki to automatically create Category pages whenever a page is saved with category links and the corresponding category doesn't already exist. Pages are created only if the author has appropriate write permissions into the group. To enable this behavior, add the following to local/config.php:
  $AutoCreate['/^Category\\./'] = array('ctime' => $Now);
• Sites with wikiwords enabled can now set $WikiWordCount['Wiki Word'] to -1 to indicate that 'Wiki Word' should not be spaced according to $SpaceWikiWords.
• Wiki Words that follow # or & are no longer treated as Wiki Words.
• Links to non-existent group home pages (e.g., [[Group.]] and [[Group/]]) will now go to the first valid entry of $PagePathFmt, instead of being hardcoded to "Group.Group". For example, to set Pm Wiki to default group home pages to $DefaultName, use
  $PagePathFmt = array('{$Group}.$1', '$1.{$DefaultName}', '$1.$1');
• Pm Wiki now provides a $CurrentTimeISO and $TimeISOFmt variables, for specifying dates in ISO format.
• Cookbook authors can use the internal Pm Wiki function Update Page? (temporarily documented at DebuggingForCookbookAuthors) to change page text while preserving history/diff information, updating page revision numbers, updating Recent Changes pages, sending email notifications, etc.
• Skin templates are now required to have <!--HTML Header?--> and <!--HTML Footer?--> directives. Setting $EnableSkinDiag causes Pm Wiki to return an error if this isn't the case for a loaded skin. Skins that explicitly do not want HTML Header? or HTML Footer? sections can use <!--No HTML Header?--> and <!--No HTML Footer?--> to suppress the warning.
• Added a new "pre" wikistyle for preformatted text blocks.
• The xlpage-utf-8.php script now understands how to space UTF-8 wikiwords.
• Searches on utf-8 site are now case-insensitive for utf-8 characters.
• Many Abort() calls now provide a link to pages on pmwiki.org that can explain the problem in more detail and provide troubleshooting assistance.
• Pm Wiki no longer reports "?cannot acquire lockfile" if the visitor is simply browsing pages or performing other read-only actions.
• The $EnableReadOnly configuration variable can be set to signal Pm Wiki that it is to run in "read-only" mode (e.g., for distribution on read-only media). Attempts to perform actions that write to the disk are either ignored or raise an error via Abort().
• Including authuser.php no longer automatically calls Resolve Page Name?().
• Authentication using Active Directory is now simplified. In Site.Auth User or the $AuthUser variable, set "ldap://name.of.ad.server/" with no additional path information (see Pm Wiki.Auth User for more details).
• Pages are now saved with a "charset=" attribute to identify the character set in effect when the page was saved.
• The phpdiff.php algorithm has been optimized to be smarter about finding smaller diffs.
• Removed the (deprecated) "#wikileft h1" and "#wikileft h5" styles from the pmwiki default skin.
• The mailposts.php and compat1x.php scripts have been removed from the distribution.

Version 2.1.27 (2006-12-11)

This version backports from 2.2.0-beta a bugfix for $TableRowIndexMax and also support for the {*$Variable} markup.

Version 2.1.26 (2006-09-11)

This version fixes a bug in feeds.php that would cause feed entries to be mixed up.

Version 2.1.25 (2006-09-08)

This release fixes a bug in authuser.php introduced by the 2.1.24 release.

The skin template code has also been extended to allow <!--XMLHeader--> and <!--XMLFooter--> as aliases for <!--HTMLHeader--> and <!--HTMLFooter-->.

Version 2.1.24 (2006-09-06)

This release makes some improvements and fixes to the AuthUser
capability.

A bug in authuser.php that had trouble dealing with non-array values in $AuthUser has been fixed.

It is now possible to specify group memberships from local/config.php (remember that such entries must come before including the authuser.php script):

    # alice and bob's passwords
    $AuthUser['alice'] = crypt('alicepassword');
    $AuthUser['bob'] = crypt('bobpassword');

    # members of the @writers and @admins groups
    $AuthUser['@writers'] = array('alice',  'bob');
    $AuthUser['@admins'] = array('alice', 'dave');

    # carol is a member of @editors and @writers
    $AuthUser['carol'] = array('@editors', '@writers');

Auth User can now read from Apache-formatted .htgroup files. The location of the .htgroup file can be done either in local/config.php or Site.AuthUser

    # local/config.php:
    $AuthUser['htgroup'] = '/path/to/.htgroup';

    # Site.Auth User
    htgroup: /path/to/.htgroup

Versions 2.1.21, 2.1.22, 2.1.23 (2006-09-05, 2006-09-06)

This release closes a potential security vulnerability for sites
that are running with 'register_globals' set to on. Details of
the vulnerability will be forthcoming on the mailing list
and site.

Sites that are running with PHP 'register_globals' and 'allow_url_fopen'
set to 'On' should upgrade to this release at the earliest
opportunity. If upgrading isn't an option, contact Pm for
a patch to older versions.

There is now a tool available to analyze Pm Wiki sites for security
and other configuration settings, see PmWiki:SiteAnalyzer.

Version 2.1.23 also corrects a bug that prevented Pm Wiki from being
able to read pagefiles created by versions of Pm Wiki before 0.5.6.

Version 2.1.20 (2006-09-04)

More minor bugfixes:

• Corrected a bug with Wiki Word references appearing in the (:attachlist:) markup.
• Restore ability to remove/override Pm Wiki's default CSS settings.

Version 2.1.19 (2006-08-30)

This release provides a number of very minor bugfixes and
enhancements:

• Fixed a bug in the pageindex code that was causing it to not regenerate as quickly as it should.
• Fixed image/object/embed handling in wikistyles to better support the Cookbook:Flash recipe.
• Fixed a bug with wikistyles and input form tags.

The next release(s) may have a number of substantial code
enhancements and changes, so this release simply closes out
a few items before introducing those changes.

Version 2.1.18 (2006-08-28)

This release closes a potential cross-site scripting vulnerability
that could allow authors to inject Javascript code through the
various table markups.

The release also adds a new (:input image:) markup to generate
image input tags in forms.

Finally, this release corrects a problem with ?action=print
failing to properly set the {$Action} page variable.

Version 2.1.17 (2006-08-26)

This release fixes a long-standing bug with $EnableIMSCaching
(PITS:00573), whereby login/logout operations wouldn't invalidate
browser caches, causing some people to see versions of a page prior
to the login/logout taking place.

The new IMS caching code maintains a "imstime" cookie in the
visitor's browser that keeps track of the time of last login,
logout, author name change, or site modification. This cookie
is then used to determine the proper response to browser requests
containing If-Modified-Since headers. (Previously only the
time of the last site modification was available.)

Browsers which do not accept cookies will effectively act as
though IMS caching is disabled.

Version 2.1.16 (2006-08-26)

This release makes some improvements to skin handling -- primarily
this improves the capability of relocating skin files to other
locations, and to provide the ability for recipes to insert items
at the end of HTML output.

This release introduces a <!--HTMLFooter--> directive into
skin templates, which allows recipes and local
customizations to insert output near the end of a document
using a $HTMLFooterFmt array from PHP.

Also, the <!--HeaderText--> directive, which inserts the
contents of $HTMLHeaderFmt into the output, has now been
renamed to <!--HTMLHeader-->. Pm Wiki will continue to
recognize <!--HeaderText--> to preserve compatibility with
existing skins, but <!--HTMLHeader--> is preferred.

A new $SkinLibDirs array has been introduced which allows
the source locations and urls for skins to be specified from
a customization file. By default $SkinLibDirs is set as

  $SkinLibDirs = array("./pub/skins/\$Skin"      => "$PubDirUrl/skins/\$Skin",
                  "$FarmD/pub/skins/\$Skin" => "$FarmPubDirUrl/skins/\$Skin");

The keys (on the left) indicate the places to look for a "skin .tmpl
file" in the filesystem, while the values (on the right) indicate the
url location of the "skin css file". Modifying the value of
$SkinLibDirs allows a skin .tmpl file to be located anywhere on the
filesystem.

As far as I can see, none of the changes introduced by this
release should have any sort of negative impact on existing
sites, so it should be safe to upgrade. (If I'm wrong, please
let me know.)

Version 2.1.15 (2006-08-25)

This release includes a number of feature enhancements and code cleanups
as reported or requested by administrators.

First, Auth User's LDAP authentication system now allows the use of
a ?filter parameter, consistent with urls used for mod_auth_ldap
authorization in Apache. See the newly updated LDAP section of the
AuthUser documentation for more details.

A chicken-and-egg problem with the @_site_* authorization groups
has been resolved. It's now possible to have a page's read authorization
refer to things such as _site_edit.

Also, the Retrieve Auth Page?() function -- used for retrieving pages only
if the visitor is authorized to do so -- now recognizes a special
level parameter of 'ALWAYS', which means to always authorize access
regardless of the browser or visitors current permissions. This
may be useful for allowing certain operations to take place from
within trusted scripts without having to grant full authorization
to the browser.

Hardcoded instances of the local/ directory now use a
customizable $LocalDir variable. This variable controls where
Pm Wiki looks for local/config.php and per-group customization
files. It may be useful for some Wiki Farm contexts. Note that
this does not change or affect the location of
$FarmD/local/farmconfig.php.

Some minor internal changes have been made to
scripts/wikistyles.php to better accommodate the
wikipublisher recipe. It's probably better if we don't try
to explain them. :-)

Version 2.1.13, 2.1.14 (2006-08-15, 2006-08-16)

This release fixes a bug in handling numeric passwords, and also
allows ldaps:// authentication sources.

Version 2.1.12 (2006-08-07)

This version introduces the ability to nest divs and tables.
The standard (:table:) and (:div:) markups are still
available, except that a (:div:) may contain a (:table:)
and vice-versa.

As in previous versions of Pm Wiki, the (:div:) markup
automatically closes any previous (:div:). However, there
are now (:div1:), (:div2:), etc. markups (and the
corresponding (:div1end:), (:div2end:), ...) which can be
used to uniquely distinguish divs for nesting purposes.

To restore Pm Wiki's previous "non-nested" div behavior, set
$Transition['nodivnest'] = 1; in a local customization file.

Other changes in this release:

• Add a (:noaction:) directive to suppress display of page actions.
• Allow anchor tags to contain colons, hyphens, and dots.
• Add "white-space" as an allowed wikistyle.
• Other minor bug fixes and typographical corrections.

Version 2.1.11 (2006-06-09)

This is a minor update that prevents %define=% wikistyles
from generating empty paragraphs in the HTML output. Prior to
this release, markup lines containing only wikistyle definitions
would often generate empty paragraphs (

Version 2.1.10 (2006-06-03)

Version 2.1.4 introduced an {$Action} page variable that would
contain the current ?action= value. Unfortunately, this page
variable conflicted with a pre-existing $Action global variable
that was being used by skins to display a human-friendly form of
the current action. Since there's not really a clean way to resolve
this, I've decided to keep {$Action} as a page variable
with the current action value (as introduced in 2.1.4), and change
the global for skins to be $ActionTitle. This will require updating
skins to use $ActionTitle instead of $Action. I apologize for the
conflict.

This release adds a Site.Local Templates? page for the fmt=#xyz
option in pagelist and search results. The list of pages to be
searched can be customized via the $FPLTemplatePageFmt variable.
The fmt=#xyz option will now also search the current page for
a matching template before searching Site.Local Templates?
and Site.Page List Templates.

The 'pmwiki' skin now places a around the "Recent Changes"
link in the header to make it somewhat easier to style.

Version 2.1.9 (2006-06-02)

This release fixes a long-standing and difficult-to-find bug with
the handling of [[~Author]] links.

Version 2.1.8 (2006-06-01)

This release simply changes the $NotifyListFmt variable to be
$NotifyListPageFmt (more descriptive), and adds a $NotifyList
array that can be used to specify notification entries from
a configuration file.

Version 2.1.7 (2006-05-31)

This release introduces a variety of improvements and bugfixes.

Vspace paragraphs are now divs:
Version 2.1.7 changes the way that Pm Wiki handles vertical
space in output (the infamous <p class='vspace></p> sequence).
Instead of using paragraphs, Pm Wiki now generates
<div class='vspace'></div> for vertical space sequences.
In addition, Pm Wiki is able to collapse the vspace

    
is automatically converted to

    
...paragraph text...
This allows for better control over paragraph spacing.  It is

expected that this change in vspace handling will not have

any detrimental effects on existing sites.  Sites that have

set custom values for $HTMLVSpace will continue to use the

custom value.  A site that wants to restore Pm Wiki's earlier

handling of vspace can do so by adding the following to

local/config.php:

    $HTMLVSpace = "
";
Improved email notifications of changes:  Version 2.1.7

incorporates a notify.php script that provides improved

capabilities for sending email notifications in response to

page changes.  This script is intended to replace the previous

MailPosts capability, which is now deprecated (but will

continue to be supported in Pm Wiki 2.1.x).  Details and 

instructions for using notify.php are in the PmWiki.Notify page.

Added 'group home page' syntax: A group name followed

by only a dot or slash is automatically treated as a reference

to the group's home page, whatever it happens to be.  This simplifies

some pagelist templates as well as a number of other items. 

In particular, group links in pagelist output now points to the

correct locations (instead of being a page in the current group).

Several bugs and vulnerabilities have been fixed:
The default width of edit forms is now more appropriate for Internet Explorer.
Authentication failure messages from LDAP are now suppressed.
Some cross-site scripting vulnerabilities in uploads and page links have been corrected (courtesy Moritz Naumann, http://moritz-naumann.com).
A problem with invalid pagenames resulting in redirect loops has been corrected.
Version 2.1.6 (2006-05-22)
The primary improvement in this release is the addition of 

a pagename argument to the (:if auth:) conditional markup.

Thus one can display markup based on a visitor's authorization

to a page other than the current one.  For example, to test

for edit privileges to Main.WikiSandbox, one would use

(:if auth edit Main.WikiSandbox:).  As before, if the

pagename is omitted the directive tests authorization to

the current page.

This release also restores the ability to have hyphens in

Inter Map link names.

Lastly, the release closes a potential cross-site scripting

vulnerability in the Wiki Trail? markup, and provides some small

performance improvements.

Version 2.1.4, 2.1.5 (2006-03-29)
This release fixes a few more bugs:
Pagelist-based feeds using ?action=rss work again.
Multi-term searches with special characters is fixed.
The release also adds a couple of items:
There is now an {$Action} page variable.
Usernames and passwords submitted to authuser.php can contain quotes.
The (:attachlist:) command now uses a natural case sort.
Version 2.1.3 (2006-03-17)
This release fixes a bug that prevents the lines= option from

working on sites running PHP 5.1.1 or later.  It also re-fixes

a bug involving empty passwords and LDAP authentication.

Version 2.1.2 (2006-03-16)
This release fixes a bug with handling "nopass" passwords.  It also

makes some speed improvements to large web feeds, and fixes a couple

of minor HTML tag mismatches.

Version 2.1.1 (2006-03-13)
This release primarily fixes a bug with passwords containing

multiple authorization groups, and in the process slightly liberalized

the formatting of "@group" and "id:name" handling.  This release also 

adds a new mechanism for managing and displaying FAQ pages.

Version 2.1.0 (2006-03-12)
This set of release notes is fairly lengthy, as it chronicles all of the changes since 2.0.13 (four months of development).  A lot remains the same, but some changes warrant extra care when upgrading from a 2.0.x version to 2.1.0 (thus the major revision number change).  As always, questions and issues can be mailed to the pmwiki-users mailing list.

Here's the list:

Wiki Words are now disabled by default.  To enable them, set "$LinkWikiWords = 1;" in a local customization file.  As of 2.1.beta2, you can now leave Wiki Words enabled but have links to non-existent pages display without decoration -- to do this, place the following lines in pub/css/local.css:
    span.wikiword a.createlink { display:none; }
    span.wikiword a.createlinktext 
      { border-bottom:none; text-decoration:none; color:inherit; }
The (:pagelist:) code has been substantially revised.  Pagelist formatting can now be specified using markup, and several defaults are available from Site.PageListTemplates.  Also, several built-in pagelist formatting functions (FPL Simple?, FPL By Group?, FPL Group?) are now removed in favor of the template code.  The FPL By Group? function can be restored by setting $Transition['fplbygroup']=1; . Remark: Check to see if your page Site.PageListTemplates is not passwordprotected for viewing, otherwise the resulting pagelist will not be shown. 
(:pagelist:) now also understands wildcards in group= and name= arguments, as well as excluding specific names and groups.
(:pagelist:) now has an "order=random" option.
(:searchbox:) now accepts "group=", "link=", "list=", etc. options to be passed along to the search results.  It also accepts a "target=" option that identifies the page on which to send the search query.
?action=search will display the contents of the current page if it contains a (:searchresults:) directive, otherwise it uses the content of the page identified by $PageSearchForm (default is the search page for the current language translation).  
Pm Wiki no longer maintains a ".linkindex" file -- it now has a ".pageindex" file that contains not only a table of links, but also words used in each page (to speed up term searches).  The maintenance of the .pageindex file can be disabled by setting $PageIndexFile=''; 
The $EnablePageListProtect variable now defaults to true, so that read-only pages appear in pagelists only if the visitor has read authorization.  Note that this can also slow down some (:pagelist:) and search commands, so if the site doesn't have any read-only pages or if you aren't worried with cloaking read-only pages from searchlists, it might be worth setting $EnablePageListProtect=0; .
Whitespace indentation rules now exist and are enabled by default.  Any line that begins with whitespace and aligns with a previous list item is considered to be "within" that list item.  Text folds and wraps as normal, and the (:linebreaks:) directive is honored.  To turn off whitespace indentation, use DisableMarkup('^ws');.
A single blank line after a !!Heading is silently ignored.
The (:redirect:) directive is now a true markup, and can be embedded inside conditional markups or includes.  It also allows redirecting to an anchor in a page, such as (:redirect PageName#anchor:).  A new from= option allows the redirect to take place only from pages that match the given wildcard specification.  The status= option allows a 301, 302, 303, or 307 HTTP status code to be returned.
The built-in authorization function has gone through some substantial internal changes, however these changes should be fully backward compatible so that it doesn't impact any existing sites.  (If it does cause a problem, please let me know so I can investigate why!)  The password prompts are now specified by an admin-customizable Site.Auth Form page.  In addition, the authorization function no longer creates PHP sessions for visitors that aren't being authenticated.
The authuser.php has likewise been substantially updated.  The new version should have complete backwards compatibility with previous authuser.php settings, but this version also offers the ability to configure authentication resources and authorization groups through the Site.AuthUser page.  Note that by default the Site.Auth User page can only be edited using the admin password.
The $EnableSessionPasswords variable can be used to control whether passwords are held in PHP sessions.  (This does not affect user authentication via AuthUser, however.)
The $Author variable now defaults to $AuthId if not otherwise set by a script or cookie.
The Site.SideBar page now defaults its edit password to the sitewide edit password (in $DefaultPasswords['edit']).
Pm Wiki now supports a "draft edit" mode, enabled by $EnableDrafts = 1.  This creates a "Save as draft" button that will save a page under a "-Draft" suffix, for intermediate edits.
There is now an ?action=login action available.
A potential security vulnerability for sites running PHP 5 with register_globals enabled has been fixed.
The [[PageName |+]] markup is now available by default; this creates a link to PageName and uses that page's title as the link text.
What used to be "markup variables" are now "page variables".  These are always specified using the {$variable} syntax, and can be used in markup and in $...Fmt strings.  In addition, one can request a value for a specific page by placing the pagename in front of the variable, as in {pagename$variable}.
The scripts/rss.php script is now scripts/feeds.php, and is a complete redesign for web feed generation.  The new version supports UTF-8 and other encodings, can generate Atom 1.0 (?action=atom), Dublin Core Metadata (?action=dc) output, and enclosures for podcasting.  It also allows feeds to be generated from trails, groups, categories, and backlinks, and provides options (same as pagelists) for sorting and filtering the contents of the feed.  Most sites can simply switch to using include_once("scripts/feeds.php"); instead of the previous rss.php include.  The rss.php file has been removed from the distribution (but still works with Pm Wiki 2.1 for those sites that wish to continue using it).
InterMap entries can now come from a Site.InterMap page as well as the local/localmap.txt and local/farmmap.txt files.  The format of these files has changed slightly, in that the Inter Map name should now have a colon after it (previously the colon was omitted).
We can now provide better control of robot (webcrawler) interactions with a site to reduce server load and bandwidth.  The $RobotPattern variable is used to detect robots based on the user-agent string, and any actions not listed in the $RobotActions array will return a 403 Forbidden response to robots.  In addition, setting $EnableRobotCloakActions will eliminate any forbidden ?action= values from page links returned to robots, which will reduce bandwidth loads from robots even further (PITS:00563).
Non-existent page handling has been improved; whenever a browser hits a non-existent page, Pm Wiki returns the contents of Site.Page Not Found and a 404 ("Not Found") status code.
Page links that have "?action=" in their query arguments are now treated as "existing page" links even if the page does not exist.
The Pm Wiki default skin now adds rel='nofollow' to various action links.
Some of the CSS styles in the Pm Wiki default skin have been changed for better presentation.
The gui edit buttons have transparent (instead of white) borders so they integrate better into skins.
The $EnableIMSCaching variable is now much smarter, it can detect changes in local customization files as well as pages.
WikiStyles can now make percentage specifications by using "pct" to mean "%".
Class attributes in WikiStyle shortcuts are now cumulative, so that %class1 class2% results in class='class1 class2' instead of just class='class2' in the output.
A problem with the (:include PageName#from#:) markup not working has been fixed (PITS:00560).
Viewing a Group Header or Group Footer page no longer displays the contents twice.
It's now easier to share pages among multiple sites (e.g., WikiFarms), see Cookbook:SharedPages (PITS:00459).
A problem with nested apostrophe markups has been fixed (PITS:00590).
Pm Wiki is now smarter about not surrounding block HTML tags with 
...
 tags.
If an [[#anchor]] is used more than once in a page, only the first generates an actual anchor (to preserve XHTML validity).
There are now (:if equal ...:) and (:if exists pagename:) conditional markups.
Compound conditional markup expressions are now possible -- e.g. (:if [ group PmWiki && ! name PmWiki ] :) .
Added an $InputValues array that can supply default values for certain form controls (PITS:00566).
The default setting of $UploadUrlFmt is now based on $PubDirUrl instead of $ScriptUrl.
The $text global variable has been removed (use $_GET['text'], $_POST['text'], or $_REQUEST['text']).
A possible problem with url-encoding of attachments with non-ASCII characters has been addressed (PITS:00588).
Page actions in non-existent pages no longer display with non-existent link decorations.
A README.txt file has been added, and several documentation files are now available through the docs/ directory.
Pm Wiki is no longer available through CVS on sourceforge.net.  It is now available via SVN on pmwiki.org, at svn://pmwiki.org/pmwiki/tags/latest .  For more details, see PmWiki:Subversion.
The $NewlineXXX variable (deprecated in 2.0.0) has been removed.
There is experimental support for server-side caching of pages that take a long time to render; this is currently an unsupported feature and may be removed in future releases.
Wiki administrators should note that from this release on Pm Wiki defaults to having Wiki Words disabled.

To make sure Wiki Words are enabled, use $LinkWikiWords = 1; in

the local/config.php file.
