Versioning scheme for WebP library

[Shubham Chandra Gupta]

Hi All,

What is the versioning scheme followed by webp library to indicate api/binary incompatibility.

Can we assume that all 0.4.x versions are going to be api/binary backward compatible with each other, but 0.5.x versions may not be compatible with 0.4.x versions.

Thanks,

Shubham

Hi,

Yes that's the idea. 0.4.x is compatible as far as the public api is concerned, technically on Linux you might run into an issue when using a shared object that wasn't built with visibility=hidden, this is now the default for 0.5.x and always was for Windows DLLs. The NEWS file makes some mention of incompatibility, in general the changes have been additive with a few configuration behavior changes along the way.
