The PHP development team just released 5.3.8. It’s an important bug fix release that solves two new bugs that were introduced in 5.3.7:
- Fixed bug #55439 (crypt() returns only the salt for MD5)
- Reverted a change in timeout handling restoring PHP 5.3.6 behavior, which caused mysqlnd SSL connections to hang (Bug #55283).
My advise is to upgrade as soon as possible. I haven’t found any problem with this version and I installed it on most of my test and production servers.
To see the buglist solved in this release, read them in the ChangeLog.
