Also: - Drop LANGUAGES variable setting, now ignored by the sagemath build system. - Drop unused SAGE_CBLAS variable from /usr/bin/sage. - Do not force the C locale when launching sagemath. - Allow the user to override SAGE_DEBUG in /usr/bin/sage. - Add -ecm, -giac, and -latte patches to fix interactions with external tools. - Add -sigfpe patch from upstream. - Fix flask_autoindex and flask_openid imports in sagenb. - Add Education category to the desktop file (bz 1624545). - Fix SINGULAR_SO variable in /usr/bin/sage (bz 1636759 and 1655248). - Invoke twistd-2 instead of twistd (bz 1640890). - Improve jupyter integration (bz 1663165). - Move existing jupyter integration into the notebook subpackage. - Require python-jupyter-filesystem instead of owning its directories. - Drop one more remnant of the F24 to F25 upgrade fixup.
