This version of ZDoom must be compiled with any version between 4.22 and 4.28 inclusive.
Use of the latest 4.26 is recommended though due to technical issues with 4.28.
- Pretty sure the minimum FMOD version is 4.22. SVN r2174 (trunk) 2010-02-23 23:40:39 +00:00			`This version of ZDoom must be compiled with any version between 4.22 and 4.28 inclusive.`
- The Wiki seems to imply that FMod 4.28 is not the best choice for ZDoom so mention this in fmod_version.txt. SVN r2553 (trunk) 2010-08-19 07:59:32 +00:00			`Use of the latest 4.26 is recommended though due to technical issues with 4.28.`
