Hi

Debian will enter freeze in January to prepare next Debian release. Currently, Debian ships libtommath 1.2.0.

If you think libtommath should be updated for next Debian release, you should cut a new libtommath release no later than December.

All the best

Dod (for Debian)

Hi,

Do you have plans or ETA of when the next stable version will be released?

Thanks, Jithin

[dod38fr]

Hi The next Debian stable version (2) will be released in Summer 2023.

To prepare this release, freeze will begin in January.

All the best

Hi

Debian will begin freeze process in January to prepare Debian 12 release. Currently, Debian still ships libtommath 1.2.0 which is 3 years old.

If you think libtommath should be updated for Debian 12, you should cut a new libtommath release as soon as possible.

All the best

Dod (for Debian)

Oh crap! Too late again, hu? Otherwise: it would be ready as it it is. @sjaeckel I haven't done a proper publishing before and am too afraid to eff up, sooooo...if you don't mind :-) Or is there a hindrance I am unaware of?

[dod38fr]

Oh crap! Too late again, hu?

Not too late. Barring backward compatibility issue, I should be able to update libtommath for Debian 12 if it's released in the next 3 weeks. But the sooner a new release is done, the better.

Happy new year !

[sjaeckel]

Cool, could you please take develop and check whether a release would be fine?

[dod38fr]

Unfortunately, at least a symbol is gone (mp_iseven is replaced by a #define). This breaks the ABI compatibility of libtommath.

Which means libtommath must be released with a new major version (e.g. something like libtommath.so.2.x.y). Which will requires a rebuild (and may be code modifications) of all reverse dependencies in Debian.

I'm afraid it's too late for Debian 12.

That said, I would welcome a new release, this way we'll have enough time for Debian 13.

[sjaeckel]

Could you please list all ABI breaks so we can check whether it'd make sense to take the effort to backport and release another version of libtommath.so.1? ... and at the same time also release a libtommath.so.2 ...

Hi

For what it's worth, here's a diff comparing the old and new list of symbols:

OK, we won't backport.

I'm afraid it's too late for Debian 12.

Then it is as it is.

@minad I guess you closed all those 2.0 tickets to have the release sooner?

@czurnieden @minad: Now that it doesn't matter anymore should we re-open them again and tackle them before a 2.0 or should we keep them closed and simply "slap a tag on develop"?

[czurnieden]

Now that it doesn't matter anymore should we re-open them again and tackle them before a 2.0 or should we keep them closed and simply "slap a tag on develop"?

There is nothing in the closed issues that are actually an issue in the sense of "bug or bug like" (including documentation), these were more or less discussions that were left open or--more likely--forgotten.

We have to start somewhere: why not actually just call it 2.0.0 and let the first bugfix(es) be 2.0.1 and the first change(es) 2.1.0? As the old saying goes: "Release early, release often!" (McCarthy 1995). (Assuming no conflicts with e.g.: distributions!)

And admitted: it would save me from the headaches with #523 if the version in "master" has cmake ;-)

[sjaeckel]

If I'm not mistaken this is all solved by 1.3.0.

Please re-open if that's not the case.
