      In particular to properly handle "dummy" targets like gmp/mpir,
      `sagelib` should depend upon `$(inst_$(MP_LIBRARY))`.
      Also, `sagelib` in `deps` should only depend on one Python:

      Add [https://github.com/fplll/fpylll/commit/28e5fcaeabe26d46167e75815e0d
      9a4fdfa1a973 this patch] to fpylll to make it compatible with Cython
      master. The default value for `language_level` has changed, so the
      `language_level` is best specified explicitly.
      This makes absolutely no difference with Cython 0.29.x, so it doesn't
      affect distributions.
      The patch just makes it possible to compile Sage with Cython master
      (something that I regularly do when contributing to Cython).

      Trac #27176: py3: fix doctest in generic_graph (part 1) · 6c3a7a7a
      Release Manager authored
      We fix doctests in
      - `incidence_matrix`: we change the example from `CubeGraph` to
      `PetersenGraph` as it is stable for `py2` and `py3`. It is possible to
      fix the order of the rows of the matrix with parameter `vertices`, but
      the order of the columns depends on `.edge_iterator()` which itself
      depends on `.vertex_iterator()` which is not always the same in py3 than
      in py2. An alternative would be to add parameter `edges` to the method
      to specify the ordering of the columns...
      - `eulerian_circuit`: we fix the issue by changing the way the graph. It
      changes the internal order of vertices and edges and this is sufficient
      for getting same result in py2 and py3. With original construction, the
      internal order of vertices was depending on the order of the keys of the
      input dict (might be different in py2 and py3)
      - `min_spanning_tree`: we sort the edges of the solution.

      Trac #27263: Upgrade to giac 1.5 fails to build with older libstdc++ · 6772ac9c
      Release Manager authored
      #26315 broke building giac on some systems that have a old-ish
      libstdc++.  It is completely mysterious to me ''why'' this broke when it
      worked before, and without a repository it's very difficult to determine
      what change between the versions is responsible, as there is little
      difference between the two versions in the relevant code.
      Nevertheless, it can be fixed by explicitly using `std::isnan` and
      `std::isinf` so that there is no risk of them conflicting with the libc
      math.h equivalents thereof.

      Currently, when comparing two matrices of type `Matrix_gfpn_dense`, the
      data of both is translated into a python string and then the two python
      strings are compared. That's very inefficient (because of copying data).
      Original suggestion: Use the upstream matrix comparison function.
      However, it turned out that the upstream function isn't faster than
      comparison of Python bytes. So, what this ticket does is to fix a
      potential owerflow.

      Both release announcements indicate:
      > The wheels on PyPI are linked with OpenBLAS v0.3.4+, which should

      > Downstream developers building this release should use Cython >=

      So this depends on the upgrade to OpenBLAS 0.3.5 (from 0.3.3) in #27020,
      and on the upgrade to Cython 0.29.2 in #27058.
      Debian developers warn us that !NumPy 1.16 in Debian leads to
      some deprecation warnings:
      DeprecationWarning: np.asscalar(a) is deprecated since NumPy v1.16, use
