Four years after the project's initiation, I have been honored last Tuesday in Prague (Czech Republic), in PostSharp's home country, to announce the availability of the first stable release. This release can be download from our download section.
Although everyone knows that a software of this complexity is never completely bug-free, the last release candidate has been very stable and all fixes required only minor, local and safe modifications.
The 1.0 branch now becomes a legacy branch. It will further maintained as long as another branch does not reach a higher level of stability.
This version is therefore one you can rely on.
