Issue#55 is striking again. It's now starting to cause real issues for us in Fedora Linux. Projects that depend on unicode-width can now be split into two categories:

• have not adapted to behaviour changes in 0.1.13 and only work correctly with <0.1.13 (usually depend on unicode-width^0.1.x wherex < 13)
• have adapted to behaviour changes in 0.1.13 and only work correctly with ^0.1.13 (and depend on unicode-width^0.1.13)

Even if wedid provide packages for both unicode-width <0.1.13 and >=0.1.13 (which would beunprecedented for two versions that are supposedly semver-compatible), we would need to patchall crates that currently pull in 0.1.* to have a dependency like>=0.1.0,<0.1.13 instead.

This would create situations where multiple crates in the same dependency tree pull in unicode-width at conflicting versions (either >=0.1.13 or <0.1.13), and cargo dependency resolution can't find a solution that satisfies both of these requirements. This isexactly the reason why behaviour changes are important when considering SemVer, not only API changes. So, please reconsider publishing 0.1.13+ as 0.2.x 😢
