The last committed ports version 0.10.0 [2] was necessary, because it changed the storage format. Users got about 4 weeks to migrate their old data format.

I am not sure, if v1.3.1 should also get its way into the Quarterly Branch per MFH before end of year 2020?

Submitted by Gabriel Dutra <[e-mail]> (maintainer) in PR 251229.

Tested on Poudriere (amd64, i386). 'portlint -AC' is fine.

Thanks for the fast response.

One last question: Should I also add MFH: 2021Q1 in the commit? We MFH'd v0.10.0 into 2020Q4, because users should get the possibility to migrate their data before version >= 1.0.0 ...

Sounds OK.
