natron: 2.3.15 -> 2.4.0

[vojta001]

I would also like to add myself as a maintainer of Natron, however my commit to become a maintainer currently waits for #115189. Either wait for it to be merged or I'll open another PR for it soon.

You can just cherry-pick the maintainer commit into this PR if you want.

[vojta001]

@SuperSandro2000 I changed the ffmpeg and cherry-picked the maintainers commit.

Reading @r-rmcgibbo's comment; do I understand this file correctly that I should update Natron's license to gpl2Plus?

[SuperSandro2000]

Not quite. That file is the same for both variants but the code contains a license header that mentions or later which means it is plus.

[vojta001]

Ah, I understand. Fortunately, that seems to be the case

• The last commit touching the license file
• LICENSE_SHORT.txt

[SuperSandro2000]

@vojta001 please fix the build failure on arm64

[vojta001]

@SuperSandro2000 I am afraid upstream doesn't support ARM yet NatronGitHub/Natron#277

[SuperSandro2000]

@vojta001 please resolve the merge conflict.

[vojta001]

Done, if you don't mind a merge commit. I can rebase instead

[vojta001]

Oh, but it does not build then, pythonPackages.certifi dropped support for Python 2

[SuperSandro2000]

Can we remove python2?

[stale]

I marked this as stale due to inactivity. → More info

[SuperSandro2000]

@vojta001 please rebase to fix the merge conflict

[vojta001]

Neither Natron 2.3.15, nor Natron 2.4.0 can be built without Python 2, therefore I can't fix this PR.

There is some hope though – Natron 2.5 should support Python 3 NatronGitHub/Natron#828
