This can be done either by:
* Using explicit full paths, using the $IP global for the installation directory full path, and then working down the tree from there.
* Using explicit full paths, using the "dirname(__FILE__)" directive to get a full directory path for the includer file.
* Occasionally removing the line altogether, and then for some files the inclusion is handled by the autoloader.
For example, if the "extensions/wikihiero/wh_main.php" file does an include or require on "wh_list.php", then PHP does the following:
* tries to open "wiki/wh_list.php", and fails.
* tries to open "wiki/includes/wh_list.php", and fails.
* tries to open "wiki/languages/wh_list.php", and fails.
* tries to open "wiki/extensions/wikihiero/wh_list.php", and succeeds.
So in this example, the first 3 calls can be prevented if PHP is told where the file is.
Testing Method: On a Linux box, run these commands to attach strace to all the apache2 processes, and log their system calls to a temporary file, then generate some activity, and then stop the strace:
-----------------------------------
rm /tmp/strace-log.txt
strace -tt -o /tmp/strace-log.txt -p `pidof apache2 | sed 's/ / -p /g'` &
php maintenance/fuzz-tester.php --keep-passed-tests --include-binary --max-runtime=3 > /tmp/strace-tests.txt
killall -9 strace
grep "No such file or directory" /tmp/strace-log.txt | sort -u
-----------------------------------
Any failed file stats will be marked with: "-1 ENOENT (No such file or directory)".

... There are certain to be other things too, so this is not intended to be comprehensive, rather the above just stops most of the notifications I observed.
Caches for wikis with table prefixes will be lost on upgrade, caches for wikis without table prefixes will be preserved. Custom cache keys in extensions can be migrated at leisure. Extensions which write to core cache keys should be migrated ASAP, as I have done with Special:Makesysop.
* Because we define the messages 'january-gen', 'february-gen', etc. as the genitive forms of months in Langauge::mMonthGenMsgs, I created them in the English file. This should fix the test of {{CURRENTMONTHNAMEGEN}} in the parser tests (currently seems to output "<january-gen>"), and should fix the wrong output of checkLanguage.php and transstat.php, which think that these messages are obsolete.
* Using the genitive forms of the months in Hebrew
* (bug 6939) Update to Indonesian localisation (id) #31
* Made lines from initialiseMessages() appear as list items during installation
* Moved the bulk of the localisation data from the Language*.php files to the Messages*.php files. Deleted most of the Languages*.php files.
* Introduced "stub global" framework to provide deferred initialisation of core modules.
* Removed placeholder values for $wgTitle and $wgArticle, these variables will now be null during the initialisation process, until they are set by index.php or another entry point.
* Added DBA cache type, for BDB-style caches.
* Removed custom date format functions, replacing them with a format string in the style of PHP's date(). Used string identifiers instead of integer identifiers, in both the language files and user preferences. Migration should be transparent in most cases.
* Simplified the initialisation API for LoadBalancer objects.
* Removed the broken altencoding feature.
* Moved default user options and toggles from Language to User. Language objects are still able to define default preference overrides and extra user toggles, via a slightly different interface.
* Don't include the date option in the parser cache rendering hash unless $wgUseDynamicDates is enabled.
* Merged LanguageUtf8 with Language. Removed LanguageUtf8.php.
* Removed inclusion of language files from the bottom of Language.php. This is now consistently done from Language::factory().
* Add the name of the executing maintenance script to the debug log. Start the profiler during maintenance scripts.
* Added "serialized" directory, for storing precompiled data in serialized form.
