mapblocks format and minetest version

by efa » Post

Looking in the changelog:
https://dev.minetest.net/Changelog
I cannot find the mapblocks version related to minetest version list.

If I understand well minetest 5.6.1 write mapblock version 29 while 5.3.0 use version 28, but where is the transition?

Though the new number is not mentioned explicity on the changelog, the relevant line in the changelog is
5.4.0 -> 5.5.0 changelogs, Minetest Wiki wrote: New maps are now zstd compressed to reach faster and/or more efficient compression
So 5.5.0 is the version that saw the introduction of mapblock version 29 which continues to today.

Hope that helps :)

yes. THANKYOU. So till 5.4.0 I can save a world and use it with native Debian 11 Minetest that is 5.3.0.
While using next Minetest AppImages 5.5 and 5.6 just entering a world, it is converted to the new format and then is no more compatible with 5.3.0, right?

Correct, so if you ever open a world on a version of 5.5.x or higher, the world has undergone a one-way conversion. Keep a backup if it's important to you to be able to use an old version, e.g. if there is a mod compatibility problem.

should be warned in release notes for 5.5 version so users are aware of the one way conversion

IIRC I actually brought that up, but it was dismissed.
