  11 This is a testing preview release, being put out mainly to aid testers in

  13 NOT to run a live production web site on this alpha release.

  21 === Big changes ===
  22
  23 Schema:
  24   The core table schema has changed significantly. This should make better
  25   use of the database's cache and disk I/O, and make significantly speed up
  26   rename and delete operations on pages with very long edit histories.
  27
  28   Unfortunately this does mean upgrading a wiki of size from 1.4 will require
  29   some downtime for the schema restructuring, but future storage backend
  30   changes should be able to integrate into the new system more easily.
  31
  32 Permalinks:
  33   The current revision of a page now has a permanent 'oldid' number assigned
  34   immediately, and the id numbers are now preserved across deletion/undeletion.
  35   A permanent reference to the current revision of a page is now just a matter
  36   of going to the 'history' tab and copying the first link in the list.
  37
  38 Page move log:
  39   Renames of pages are now recorded in Special:Log and the page history.
  40   A handy revert link is available from the log for sysops.
  41
  42 Editing diff:
  43   Ever lost track of what you'd done so far during an edit? A 'Show diff'
  44   button on the edit page now makes it easy to remember.
  45
  46 Uploads:
  47   It's now possible to specify the final filename of an upload distinct
  48   from the original filename on your disk.
  49
  50   An image link for a missing file will now take you straight to the upload page.
  51
  52   More metadata is pre-extracted from uploaded images, which will ease pressure
  53   on disk or NFS volumes used to store images. EXIF metadata is displayed on
  54   the image description page if PHP is configured with the necessary module.
  55
  56 User accounts:
  57   There are some changes to the user permissions system, with assignable
  58   groups. This is still somewhat in flux; do not rely on the present system
  59   that you see in this alpha to still be there.
  60
  61 E-mail:
  62   User-to-user e-mail can now be restricted to require a mail-back confirmation
  63   first to reduce potential for abuse with false addresses.
  64
  65   Updates to user talk pages and watchlist entries can optionally send e-mail
  66   notifications.
  67
  68 External hooks:
  69   A somewhat experimental interface for hooking in an external editor
  70   application is included. This may not be on by default in final release,
  71   depending on support.
  72
  73 And...
  74   A bunch of stuff we forgot to mention.
  75
  76
  77 === What's gone? ===
  78
  79 Latin-1:
  80   Wikis must now be encoded in Unicode UTF-8; this has been the default for
  81   some time, but some languages could optionally be installed in Latin-1 mode.
  82   This is no longer supported.
  83
  84 MySQL 3.x:
  85   Some optimization hacks for MySQL 3.x have been removed as part of the schema
  86   clean-up (specifically, the inverse_timestamp fields). MediaWiki 1.5 should
  87   still run, but wikis of significant size should very seriously consider
  88   upgrading to a more modern release. MySQL 3.x support will probably be
  89   entirely dropped in the next major release later this year.
  90
  91 Special:Maintenance
  92   These tools were, ironically enough, not really maintained. This special
  93   page has been removed; insofar as some of its pieces were useful and haven't
  94   already been supplanted by other special pages they should be rewritten in
  95   an efficient and safe manner in the future.
  96
  97
  98 === What's still waiting? ===
  99
 100 These things should be fixed by the time 1.5.0 final is released:
 101
 102 Upgrade:
 103   Wikis in Latin-1 encoding are no longer supported; only Unicode UTF-8.
 104   A new option $wgLegacyEncoding is provided to allow on-the-fly recoding of
 105   old page text entries, but other metadata fields (titles, comments etc) need
 106   to be pre-converted. The upgrade process does not yet fully automate this.
 107
 108   In general the upgrade from 1.4 to 1.5 schema has not been tested for all
 109   cases, and there may be problems.
 110
 111 Backups:
 112   The text entries of deleted pages are no longer removed from the main
 113   text table on deletion. If you provide public backup dumps of your databases,
 114   you will probably want to use the new XML-format dump generator... but
 115   this hasn't been finished yet.
 116
 117 PostgreSQL:
 118   The table definitions for PostgreSQL install are out of date, and patches
 119   to support PostgreSQL from the main installer are still pending.
 120
 121 MySQL 4.1+:
 122   Proper charset encoding / collation configuration for installs on MySQL 4.1
 123   and higher still needs to be fiddled with. Some bits may fail on the UTF-8
 124   setting due to some long field keys.
 125
 126 Authentication plugin fixes:
 127   The AuthPlugin interface needs some improvements to work better with LDAP,
 128   HTTP basic auth, and other such environments. Some patches are pending.
 129

 167 === Caveats ===
 168
 169 Some output, particularly involving user-supplied inline HTML, may not
 170 produce 100% valid or well-formed XHTML output. Testers are welcome to
 171 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 172 cases, but this is not recommended on live sites. (This must be set for
 173 MathML to display properly in Mozilla.)

 187
 188 === Mailing list ===
 189
 190 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 191 wikitech-l list:
 192
 193   http://mail.wikipedia.org/mailman/listinfo/mediawiki-l
 194
 195 A low-traffic announcements-only list is also available:

 197
 198 It's highly recommended that you sign up for one of these lists if you're
 199 going to run a public MediaWiki, so you can be notified of security fixes.
