Although the TYPO3 developers clearly write down all changes, it is not very easy to understand and convenient for people who just want to know the interesting changes. This document aims to give you a short sum-up.
Intended Audience
This document is made for all TYPO3 users who would like to have a short overview of what has changed in the new TYPO3 release version 4.0.3. This is a maintenance release, it does not contain any feature enhancements.
For latest information on this release please see [1].
For general information about the release workflow of TYPO3 please see [2]
Installation and upgrade
Upgrading from previous versions of the 4.0 branch (4.0, 4.0.1 or 4.0.2) does not require any database changes, so you can simply exchange the sources and you're done. However, in order to benefit from the new and updated tsconfig_help tables which were shipped with 4.0.2, you need to go to the Install Tool -> Database Analyser -> Import.
Upgrading from releases previous to 4.0 should be straight forward as well, just follow the instructions of the Upgrade Wiki page [3].
Fixes
Internet Explorer 7 compatibility:
TYPO3 works with almost every recent browser, but it failed to show the right-click menu when working with the new IE 7. Some small changes bring back this functionality to IE users.The ADODB system extension updated to upstream 4.93
ADODB is an extension which is used by the database abstraction layer (DBAL) of TYPO3. This allows to run TYPO3 databases on non-MySQL systems. It provides support for a variety of database management systems, e.g. Oracle and PostgreSQL. For more information about DBAL, see http://typo3.org/development/projects/database-abstraction/.A small bugfix for Indexed Search in combination with DBAL has been applied
Some minor fixes to the Extension Manager
It has been recognized that the Extension Manager requires a lot of memory. A solution for this problem is under way and will be shipped together with TYPO3 4.1.A fix which was introduced in TYPO3 4.0.2 was not working in combination with DBAL (see above). A new solution for the initial problem was required to fix this.
Some small tweaks for PHP5 were made
Fixed a JavaScript error on the right-click menu in the filelist module
It may have happened that the right-click menu did not show up on folders containing special characters.TYPO3 4.0 introduced a new feature to allow extensions write to syslog (t3lib_div::syslog). Optionally it offers logging into a separate file. However, before that version, the time format was wrong.
Some fixes for the Tools>User Admin Module “SU” mode
In past versions it was possible to SU to oneself and/or to disabled users. Pretty useless, therefore these options have been removed.The TSConfig property “options.hideRecords.pages” was ignored for mounted pages.
This problem was especially noticed by users of the DAM extension who were trying to hide the storage folder to their users.A feature allowing custom 404 (page not found) error pages (pageNotFound_handling) broke on websites with some character sets.
