Although the TYPO3 developers clearly write down all changes, it is not very easy to understand and comfortable 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 is new or has changed in the new TYPO3 release version 3.8.
Cache-Control Headers
One of the most important features in TYPO3 3.8 is the possibility to make use of so-called cache-control headers on frontend output. This allows a site to be cached by client browsers and proxies. See http://typo3.org/development/articles/using-cache-control-headers-in-typo3/ for more information.
Thanks to such cache-control headers, browser clients and proxy servers become aware of how long a sent page can be cached (or in other words: how long it is not needed to re-fetch it again).
The result of that is a big speed gain for servers who might have been permanently under high load because proxy server never cached their contents.
Indexed Search
TYPO3s powerful search engine has got some high improvements.
It now can offer statistics of entered search words, supports a lot of new file types for indexing (Excel tables, Powerpoint presentations, StarOffice/OpenOffice.org documents and even some more...). Furthermore, indexed search now contains support for "crawler" extensions which makes it possible to index all pages automatically by simply starting one of these crawlers from the backend of TYPO3.
