- Add `--prerelease` flag, which will be `False` by default. This is a behavioral change and that's basically why I'm doing a new major release. All other changes are minor here. - Better docs.
- Make Copier work fine with Git 2.28. - We have [docs](https://copier.readthedocs.io/)! - Polish docs a little bit. - We now run tests on macOS and Windows!
- Remove semver to avoid having 2 different versioning systems. We stick to PEP 440 now. - Remember where an answer comes from. - Do not re-ask to the user if already answer via `--data`. - Support pre-migration scripts that modify the answers file.
