+ikiwiki.info has upgraded to the not yet released ikiwiki 2.30. This
+version of ikiwiki drops support for subscribing to commit mail
+notifications for pages. The idea is that you can subscribe to the new
+[[RecentChanges]] feed instead. (Or create your own custom feed of only the
+changes you're interested in, and subscribe to that.)
+
+So if you were subscribed to mail notifications on here, you'll need to
+change how you keep track of changes. Please let me know if there are any
+missing features in the [[RecentChanges]] feeds.
+
+Statically building the RecentChanges also has performance implications,
+I'll keep an eye on [[server_speed]]..

-ikiwiki 2.10 released with [[toggle text="these changes"]]
-[[toggleable text="""
-   * Tidy ctime debug output for git.
-   * French translation update. Closes: #[445923](http://bugs.debian.org/445923)
-   * Fix --get-ctime with git, needed to remove srcdir from filename.
-   * In the cgi edit path, reload the index file before rendering. A bug
-     showed up where a web edit that added a page caused a near-concurrent
-     web edit to fail in will\_render. While it would be hard to reproduce this,
-     my analysis is that the failing cgi started first, loaded the index file
-     (prior to locking) then the other cgi created the new page and rendered
-     it, and then the failing cgi choked on the new file when \_it\_ tried to
-     render it. Ensuring that the index file is loaded after taking the lock
-     will avoid this bug.
-   * Fix strange stderr-hiding code in the git module, allow error messages
-     to be passed on to stderr. Also fixes a potential bug, since git error
-     meesages were treated as if they came from git stdout.
-   * Add a "createlink" class attribute to the span for wikilinks pointing
-     to not-yet-existing pages. I don't have a useful style defined for that
-     though.
-   * Rewritten rst plugin by madduck is a python program that communicates with
-     ikiwiki via XML RPC. This should be much faster than the old plugin that
-     had to fork python for every rst page render. Note that if you use
-     the rst plugin, you now need to have the RPC::XML perl module installed.
-   * Danish translation from Jonas Smedegaard. Closes: #[446952](http://bugs.debian.org/446952)
-   * Support git authors of the form "joey <joey>", which is common when
-     importing from a svn repo."""]]

-News for ikiwiki 2.16:
-
-   Many of the pages in ikiwiki's basewiki have been moved and renamed in this
-   release, to avoid the basewiki including pages with names like "blog".
-   Redirection pages have been left behind for these moved pages temporarily,
-   and will be removed later.
-
-   The meta plugin no longer supports setting internal or external links
-   with "meta link". Instead, use "meta openid" for openid links, and use tags
-   for in-wiki invisible links between pages.
-
-   If you use the calendar plugin, ikiwiki is now smarter and your nightly
-   cron job to update the wiki doesn't need to rebuild everything. Just pass
-   --refresh to ikiwiki in the cron job and it will update only pages that
-   contain out of date calendars.
-
-ikiwiki 2.16 released with [[toggle text="these changes"]]
-[[toggleable text="""
-   * Major basewiki reorganisation. Most pages moved into ikiwiki/ subdirectory
-     to avoid polluting the main namespace, and some were further renamed.
-   * meta: Add redir support, based on a patch by Thomas Schwinge.
-   * Redirs added for moved basewiki pages. These will be removed in a future
-     release.
-   * Remove .otl file from sandbox to avoid build ugliness. Closes: #[454181](http://bugs.debian.org/454181)
-   * Finally implemented a simple per-page data storage mechanism for plugins,
-     via the %pagestate hash.
-   * Use pagestate in meta to detect potential redir loops.
-   * Added a version plugin that saves state about what's using it, to force
-     pages to rebuild when ikiwiki's version changes.
-   * The calendar plugin stores state about when it needs to be updated,
-     and forces rebuilds of the pages that contain calendars. So
-     running ikiwiki --refresh at midnight is now enough, no need for a full
-     wiki rebuild each midnight.
-   * calendar: Work around block html parsing bug in markdown 1.0.1 by
-     enclosing the calendar in an extra div.
-   * Fix file pruning code to work if ikiwiki is run with "." as the srcdir.
-   * Add an edittemplate plugin, allowing registering template pages, that
-     provide default content for new pages created using the web frontend.
-   * Change formbuilder hook to not be responsible for displaying a form,
-     so that more than one plugin can use this hook.
-     I believe this is a safe change, since only passwordauth uses this hook.
-     (If some other plugin already used it, it would have broken passwordauth!)
-   * Ensure that web edited pages always end in a newline.
-   * Avoid unnecessary stat calls to get mtime when rendering pages, use
-     cached value.
-   * Preserve input file modification times in output files.
-   * Allow dashes in preprocessor directive commands, and shortcuts.
-   * Htmlize parameters passed to the template preprocessor directive before
-     inserting them into the html template. This ensures that markdown
-     acts on them, even if the value is expanded inside a block-level html
-     element in the html template. Closes: #[454058](http://bugs.debian.org/454058)
-   * Use a div in the note template rather than a span.
-   * shortcut: Expand %S to the raw input text, not url-encoded.
-   * Don't increment feed numbers when an inline has no feeds. (Nis Martensen)
-   * Allow editing a page and deleting all content, while still disallowing
-     creating a new page that's entirely empty.
-   * meta: Drop support for "meta link", since supporting this for internal
-     links required meta to be run during scan, which complicated its data
-     storage, since it had to clear data stored during the scan pass to avoid
-     duplicating it during the normal preprocessing pass.
-   * If you used "meta link", you should switch to either "meta openid" (for
-     openid delegations), or tags (for internal, invisible links). I assume
-     that nobody really used "meta link" for external, non-openid links, since
-     the htmlscrubber ate those. (Tell me differently and I'll consider bringing
-     back that support.)
-   * meta: Improved data storage.
-   * meta: Drop the hackish filter hook that was used to clear
-     stored data before preprocessing, this hack was ugly, and broken (cf:
-     liw's disappearing openids).
-   * aggregate: Convert filter hook to a needsbuild hook.

+News for ikiwiki 2.30:
+
+   Ever feel that ikiwiki's handling of RecentChanges wasn't truely in the
+   spirit of a wiki compiler? Well, that's changed. The RecentChanges page is
+   now a static page, not a CGI. Users can subscribe to its rss/atom feeds.
+   Custom RecentChanges pages can be easily set up that display only changes
+   to a subset of pages, or only changes by a subset of users.
+   
+   All wikis need to be rebuilt on upgrade to this version. If you listed your
+   wiki in /etc/ikiwiki/wikilist this will be done automatically when the
+   Debian package is upgraded. Or use ikiwiki-mass-rebuild to force a rebuild.
+
+   With this excellent new RecentChanges support, the mail notification system
+   is showing its age (and known to be variously buggy and underimplemented for
+   various VCSes), and so ikiwiki's support for sending commit mails is REMOVED
+   from this version. If you were subscribed to commit mails, you should be
+   able to accomplish the same thing by subscribing to a RecentChanges feed.
+
+   The "svnrepo" and "notify" fields in setup files are no longer used, and
+   silently ignored. You may want to remove them from your setup file.

+   * Old versions of git-init don't support --git-dir or GIT\_DIR with

+   * aggregate: Fork a child process to handle the aggregation. This simplifies

+     it will automatically be cleaned up for the parent process, which proceeds
+     to render the changes.

-News for ikiwiki 2.9:
-
-   Since ikiwiki 2.0 was released, some limitiations have been added to what
-   ikiwiki considers a WikiLink. In short, if there are any spaces in between
-   the brackets, ikiwiki no longer considers it to be a WikiLink. If your wiki
-   contains things meant to be WikiLinks that contain spaces, you will need to
-   fix them, by replacing the spaces with underscores.
-   WikiLink have always been documented to not contain spaces, but bugs in
-   ikiwiki made it treat some text with spaces as WikiLinks. Most of these
-   bugs were fixed in version 2.2, and a final bug was fixed in this 2.9
-   release. These fixes are necessary to avoid ambiguity between
-   WikiLinks and PreProcessorDirectives. Apologies for any inconvenience
-   these bugs (and their fixes) may have caused.
-
-ikiwiki 2.9 released with [[toggle text="these changes"]]
-[[toggleable text="""
-   * Fix copyright and licence styling.
-   * tag: Add taglink preprocessor directive, supporting visible tag links.
-     Closes: #[443344](http://bugs.debian.org/443344)
-   * map: Fully specify paths to links to avoid issues when the bestlink
-     didn't point to the correct page.
-   * map: Render pages on the way to subpages whose parent pages
-     are not included in the map. Include special styling for such pages.
-   * map: Remove common prefixes and don't over-indent.
-   * Add class option to htmllink().
-   * img: Allow link=somepage to cause the image to link to a given page.
-     Slight overriding of link, as link=no is still used to disable the linking
-     entirely. Unless you have a page named "no"..
-   * Save index after previewing page edit, since even previewing can create
-     files in some situations, and this is appropriate in some cases, such as
-     the teximg plugin's error log file.
-     Such files will be automatically cleaned up at an appopriate later time.
-   * Don't allow whitespace in link text in a wikilink. This was still
-     allowed by the regexp in one case though not documented to work, and
-     was ambiguous with preprocessor directives.
-   * camelcase: Tighten regexp to avoid false positives. WikiWords are only
-     linkified now if they are preceeded by whitespace."""]]
