python3.13

[miettal]

pycapng has a problem of build in python 3.13, so this is a blocker for adding python 3.13 support to jageocoder.

pycapng already merged bugfix change, but the release is not yet.
capnproto/pycapnp#372

pycapng is not (well) active project. migration other capn proto library is one option, I think.

Yes, I am aware of that issue. In version 2.2, I plan to use SQLite for data management, and I am currently developing that feature.

Starting with jageocoder v2.2.0, we have redesigned the data files to no longer use pycapnp.
We have confirmed that this allows the software to run on Python 3.13 and later.
