11 This is a testing preview release, being put out mainly to aid testers in
12 finding installation bugs and other major problems. It is strongly recommended
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
130

160 === Caveats ===
161
162 Some output, particularly involving user-supplied inline HTML, may not
163 produce 100% valid or well-formed XHTML output. Testers are welcome to
164 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
165 cases, but this is not recommended on live sites. (This must be set for
166 MathML to display properly in Mozilla.)

181 === Mailing list ===
182
183 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
184 wikitech-l list:
185
186 http://mail.wikipedia.org/mailman/listinfo/mediawiki-l
187
188 A low-traffic announcements-only list is also available:

190
191 It's highly recommended that you sign up for one of these lists if you're
192 going to run a public MediaWiki, so you can be notified of security fixes.
