Source that says that IB2.5 will require MUI 5?
They've been discussing about it on IBrowse mailing list recently. Thore of course is talking for MUI5, but some others have expressed their worries. Oliver still considers if they still should have 3.8 support or not, and has been asking comments how MUI4/5 performs on real systems. I don't remember now if they did make their final decision, but at least it starts to sound that they'll likely be going for MUI5 route...
From fear of getting too far off-topic, when should we expect the new IB? I have been waiting for... well, a really damn long time.
Comment from Oliver:
"Although IB2.5 is largely ready for
release there are some things that need doing first, like updating the
versions of jpeglib, libpng and zlib currently in use. Not a massive job,
but it makes no sense doing things like this until a definite release date
is made. It is largely the AmiSSL progress that prompted me to get the
source code repo sorted out as this will be the first step required towards
making a release possible. Also, I need to figure out if we still need to
support MUI 3.8, now that 4 and 5 have been released for 68k."
