take a look to,
and then take a look to the ReleaseVersion 0.9.4, last line
Release 0.9.4 ¶
This release only contains some bugfixes and code cleanups. This release is still the old codebase. It doesn't contain any new code yet.
* Some fixed were made to the encoder. The format changed a bit so I bumped up the encoder version. Because the encoder still isn't functional for PHP version other than PHP 4 you should only use this encoder if you want to have line numbers encoded.
* In the next versions we will try to fix the encoder for PHP 5 and 5.1.
* eA should be PHP 5-compatible except for some very unusual cases.
* This version *DOESN'T* support PHP 5.1. For that, see Release-0.9.5-beta1
i hope that helps..
