      Trac #29674: fedora-32:  If gcc 10 is found, install gcc spkg; fix building gcc (9.2.0) spkg with gcc 10
      To work around build failures of some SPKGs with gcc 10, in particular
      on fedora-32 (#29456),
      we reject system gcc 10 and build the gcc spkg instead.
      That itself requires patches, which we get from
      https://bugs.gentoo.org/708346, for the following error:

      Trac #29625: support for weighted term orders in normal_basis · ec4fd4a5
      Release Manager authored
      As a follow-up to #29543, this ticket changes the `normal_basis` method
      of ideals to handle the case of weighted term orders.
      With this change, the degree of the monomials in the normal basis is
      taken with respect to the weighted degree (which agrees with Sage's
      notion of degree).
      sage: R.<x,y,z> = PolynomialRing(QQ, order=TermOrder('wdegrevlex', (1,
      2, 3)))
      sage: I = R.ideal(x*y^2 + x^5, z*y + x^3*y)
      sage: I.normal_basis(degree=9)
      [x^2*y^2*z, x^3*z^2, x*y*z^2, z^3]
      sage: all(f.degree() == 9 for f in _)
      This also came up in an [https://ask.sagemath.org/question/47623 Ask
      SageMath question].
      The implementation uses the Singular function [https://www.singular.uni-
      kl.de/Manual/4-1-2/sing_377.htm#SEC417 weightKB].

      Trac #29348: Remove dependency on 'twisted' for some unpickling in cartan_type · 6e2957b5
      Release Manager authored
      A function in `combinat/root_systems/cartan_type.py` uses Python's
      `twisted` package to do some unpickling. In #29320, we are making
      `twisted` optional, so we should remove its use from this file.

      Implement a method which returns the ramification type of a rational
      function. The ramification type is a list of lists of integers >1

      Trac #24601: 3D plot missing axis labels and tick numbers with... · fa25d32e
      Release Manager authored
      Trac #24601: 3D plot missing axis labels and tick numbers with viewer='threejs' and displayed in chrome.
      This one liner:
      does not display correctly in Chrome Version 63.0.3239.132 (Official
      Build) Built on Ubuntu , running on Ubuntu 17.10 (64-bit) or the same
      version in Windows. Sage 8.0 and 8.2beta3 produce the same HTML, other
      than the location of the threejs code. Both don't display in Chrome.
      It displays fine in firefox 58 under Ubuntu 17.10.
      My javascript skills are pretty limited. I did step through the code in
      both browsers. I didn't see any obvious differences
      I'll attach screen shots.
