Security reminder: MediaWiki does not require PHP's register_globals
setting since version 1.2.0. If you have it on, turn it *off* if you can.
-== MediaWiki 1.8 ==
+== MediaWiki 1.9 ==
THIS IS NOT A RELEASE YET.
== Configuration changes ==
-* $wgUseETag, to enable/disable sending of HTTP ETag headers
- (default: disabled)
-
== Major new features ==
-* (bug 7098) Add an option to disable/enable sending of HTTP ETag headers,

- (disabled by default).
-* (bug 550) Allow blocks on anonymous users only.
-* (bug 6420) Render thumbnails for DJVU images, support multipage DJVU display
- on image pages. Added new 'page=' thumbnail option to select a page from a

-
-== Changes since 1.7 ==
-

- indexed pager.
-* (bug 6448) Allow filtering of Special:Newpages according to username

== Compatibility ==
-MediaWiki 1.8 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
+MediaWiki 1.9 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
== Upgrading ==
-Several changes to the database have been made from 1.6:
-
-* A new "langlinks" table tracks interlanguage links
-* A new "filearchive" table stores information on deleted files
-* A new "querycache_info" table stores information on query page updates
+Some minor database changes have been made since 1.7:
+* new fields and indexes on ipblocks
+* index change on recentchanges
+Several changes from 1.5 and 1.6 do require updates to be run on upgrade.
To ensure that these tables are filled with data, run refreshLinks.php after
the upgrade.
