h2. Upgrading and compatibility
Please note that this version is released as an very early alpha release. It shows a snapshot of our development so far on the road to 4.7.0, which will be released in April/2012. Take a look at the Roadmap for more information about the schedule.
The first Alpha release concentrates on Deprecation CleanUP and Frontend-Accessibility.
To upgrade an existing installation of 4.5 to 4.6.0alpha1, please consider the following steps:
* Visit the Install Tool:
** Use the "Database COMPARE" section and apply all database schema changes.
** Use the "Update Wizard" to upgrade the compatibility to 4.7.
h2. New installations
Try out the *introduction package* which provides a very easy way of installing TYPO3 and having some example setup already in place.
If you are interested in the new accessibility features shipped for the TYPO3 frontend, switch your *introduction package* to html5 mode or try out the new invented *government packages* which aims to be the *introduction packages* preconfigured for accessibility and usage in governmental agencies.
h2. What happened so far
* *Many unused and deprecated files have been removed in*
* *indexed_search has now an extensions available which uses MySQL fulltext feature*
If you want to use and try this feature, install the additional indexed_search_mysql extensions
* *ADOdb library has been raised to version 5.14*
* *Icons for file-links in frontend are configurable*
currently there is no documentation available, which will be improved soon
* *The caching framework now uses compressed DB backend by default for pages and page_sections*
If you have less CPU power but more database space, you might want to change this manually again
* *the system extension "linkvalidator" has been integrated as submodule*
take care to run _git submodule --init_ wenn working on GIT branch
* *A new set of interfaces called "collection interfaces" has been introduced*
These interfaces define an generic and common api how to deal with sets of data in TYPO3 Core.
A new Clipboard will be based upon this, as well as the possiblity to "group" tca records or files within a collection.
Furthermore the FAL layer will use them as an interface for the represantion of an "folder".
* Frontend-Accessibility features has been integrated
