How often are libraries' trunk synchronized?

[jll63]

For those libraries that give the option of selecting the trunk, in addition to pinned releases...how frequently is the trunk synchronized with the canonical repository?

It depends on which library exactly (and language and compiler), there are situations where the general rule doesn't apply, but: trunk versions of libraries are synchronized nightly (between 3 and 5 am UTC)

Thanks. The library in question is my yomm2. C++.

yomm2's headers are updated every night as explained.

The library binary libyomm2.a that you can link against is built every night from 5 am UTC (and it will take a little while for the cache to refresh) for popular compilers like GCC 13.2 and every compiler here https://conan.compiler-explorer.com/compiler_usage.html that has 1000 or more compilers per month.
For less popular compilers it only gets built every sunday night.

Thanks. Actually yomm2 is header-only, although it can also be built as a shared library. But I installed it as header-only.

Ah right, we did build something back in July 2023, possibly because of a missconfiguration
