Background

Since Helm do not support non-semantic version after their v3.5.1 release , If we need to follow with the Helm version , we must also deprecate the non-semantic version support . We have introduced the enforce-semver2 since ChartMuseum v0.13.0 release , with this option set , we also force semver2 chart .

Decision

With Helm's officially banned non-semver2 Chart , we decide to deprecate the enforce-semver2 option , the option arg will keep , but it does nothing except the DEPRECATION WARNING . And , since chartmuseum v0.14.0 , the semver2 validation will depend on Helm's , and can not disable any more .

The notice for different kind users

• For users which need to store non-semver2 charts : Stay at v0.13.1 , but please do the migration ASAP , we'd not make any release based on the non-semver2 charts.

• For users without setting enforce-semver2: Check your customer charts version , and make sure they are all valid semver2 charts. If not , go to usercase#1 , otherwise, go to usercase#3 .

• For users already set enforce-semver2: Just go ahead to v0.14.0 , and remove the enforce-semver2 option in your bootstrap command.
