Fody Version 4 has been released.

Milestone containing all issues and PRs: https://github.com/Fody/Fody/issues?q=is%3Aclosed+milestone%3A4.0.0

This is mostly a bug fix release. There two breaking changes which justified the major version bump

• InSolutionWeavers are no longer detected by convention but must be declared explicitly: https://github.com/Fody/Fody/issues/644
• Legacy weavers that do not provide a .props file with a <WeaverFiles> entry are no longer supported: https://github.com/Fody/Fody/issues/643

The majority of users should not be affected by the above as they do not affect the consumers of weavers. The majority of weavers have been updated and smoke tested as part of updating https://github.com/Fody/FodyAddinSamples to Fody version 4. If you are producing a weaver that is publicly available on NuGet, and actively maintained, you should submit a PR with a sample for that weaver to FodyAddinSamples. This way your weaver will got smoke tested with every Fody release.

If you hit any issues with version 4, revert back to your previous version, and raise an issue https://github.com/Fody/Fody/issues
