This is a bugfix release for the 0.4.x series that contains backported fixes for important bugs that affected code generation. It also contains a fix that makes the emscripten target compatible with newer browser versions.
- Code Generator: Fix initialization routine of uninitialized internal function pointers in constructor context.
- Type System: Use correct type name for contracts in event parameters when used in libraries. This affected code generation.
- ABIEncoderV2: Refuse to generate code that is known to be potentially buggy.
A big thank you to all contributors who helped make this release possible!
