IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT
During development that followed the 2.1.4 release, some
unfortunate changes to the source code did break *binary*
compatibility of the library with previous releases. This had the
potential to severely break any system where a version of FreeType
was installed from recent CVS sources.
We did undo the changes, and everything should be completely
compatible now. However, due to other subtleties too long to be
explained here, there may still be a tiny risk that the current
sources break some rare applications.
This package is thus FreeType 2.1.5 release candidate 1 and has
been released for testing. If you install it on your system, please
be certain to be able to install a previous version in the case
where something would go wrong.
We will make the official 2.1.5 release as soon as we're convinced
that it will not break anything.
