[Debian-science-sagemath] Library transition freeze coming up on November 5

[Tobias Hansen]

Hi there,

I wanted to remind you all that the library transition freeze for Debian
stretch is on November 5. That means if we want to have a chance of
packaging Sage for the next Debian release, all libraries that already
have reverse dependencies in Debian must be up-to-date in
unstable/testing as soon as possible.

Further freeze dates:
2017-01-05: "Soft" freeze (no new packages, no re-entry, normal migrations)
2017-02-05: Full freeze

Of the packages on the Wiki page, the following look like library
transitions might be necessary:

brial/polybori (rdepends: singular)
libfplll (rdepends: gap-float, sollya)

linbox has no rdepends, but should be ready to be uploaded soon I think.

I will take care of brial, what about libfplll? Sage uses version
4.0.5+git20160331-1 and we have 4.0.4-2 in unstable and 5.0.2-1 in
experimental. We have the version used by Sage in the devel apt repo. Do
we really need that version? If yes, can that be uploaded to unstable?
Julien?

ipython is only up-to-date in experimental, does it need a transition?

Can you think of any other packages that might need a transition? We
shouldn't forget anything here.

Best,
Tobias
