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.
