It seems that anytime I'm using Almanac::latest (quickest and easiests) construction method, the cached Moon FK EPA is always discarded (CRC32 differs), download is then always needed and it regularly fails, so I re-run to pass.

Edit: well it fails on existing .lock file error, not network access error

[ChristopherRabotin]

Even with the latest code merged you get a dead lock? I need to update the CRC because I think I forgot to update it when I built the file.

Ah, my statement was based on the current stable, I should have been more accurate 😄

All my crates use the stable tags now, not branches. I may create a temporary branch for the zepto beta test, because it's huge and important, but it is also too much effort to reindex everything on different versions. I'm quite happy with the latest tags now, we can wait for newer ones

[ChristopherRabotin]

Yes, I recommend that you use explicit versions and not branches at the moment. I hope that by the end of September I'll be able to have a stable release of hifitime and ANISE, and then make whatever changes are needed as smaller increments of these stable versions. I really need to get back to hifitime so that version 4 can finally be released, there's just a lot of Python work I have not done yet :-/
