First view: Ubuntu 14.04 LTS brings PHP 5.5 and Apache 2.4
Short first view on Ubuntu 14.04 LTS (= long term service): I just tried out the alpha1 version of the upcoming Ubuntu 14.04 LTS, which will definitly become the main mainstream server os in the next few years and replace Ubuntu 12.04 LTS. Most important news so far: 14.04 LTS will install PHP 5.5 (currently 5.5.6) and Apache 2.4 (currently 2.4.7) by default. Prepare to get rid of PHP 5.3 in the next few months! MySQL ships in the 5.5 version (same like in 12.04 afaik) and Nginx comes in the 1.4.4 version, which is the latest stable one.
Ubuntu 12.04 LTS can also be updated to 14.04 with one command on the bash (after the release, not 100% sure, never tried this out):
