Changelog for the Windows Installer

0.6.3 (unreleased)

• Nothing changed yet.

0.6.2 (2021-01-05)

• Reverted use of Cygwin's system package for libntl, which is not built to be portable enough for enough users' CPUs. Likewise reverted use of system libflint package which depends on NTL.

NOTE: If you haven't experienced problems with build 0.6.1 of Sage 9.2 there is no need to upgrade to this build, as the issue this fixes only impacts some users depending on their CPU.

0.6.1 (2020-11-28)

• Updated to Python 3.7.

• Updated to Cygwin 3.1.x.

0.6.0 (2020-02-13)

• The following optional packages, and their associated Sage extensions are now come pre-installed by default:

  • bliss
  • coxeter3
  • mcqd
  • primecount
  • tdlib

• Improved support for installing additional optional packages.

• Downgraded Cygwin version in order to fix an issue with running external Windows programs from Sage (in particular, this caused problems when running external LaTeX distributions (#42).

• Build system can now use a local Cygwin mirror; this can make for more consistent builds.

0.5.2 (2020-01-08)

• Added patch from SageMath 9.0 to builds of SageMath 8.9 to fix support for threejs plots in Firefox on Windows.

• Removed unneeded static libraries from the installer, reducing install size.

0.5.1 (2019-07-12)

• Fixed installation path of the HTML documentation.

• Include a copy of the nano editor, for use with git.

• Fixed initialization of the .sage directory on new installs, ensuring that the default config files are copied to the correct locations. This fixes a bug with the default IPython terminal color scheme not being set correctly.

0.5.0 (2019-07-11)

• Debug symbols, which are not needed at runtime, are stripped from most binaries, resulting in a noticeably smaller install footprint. Now the installer and the installation itself are smaller despite packing in more features!

• Includes a copy of git in the SageMath Shell, so no need to install a separate Git or integrate an existing Git for Windows installation.

• Installing the HTML documentation is now optional. Although some help features won't work without it, it saves about 600 MB of installation size, and if you have an internet connection you can still read the docs at doc.sagemath.org.

• Updates to use a few more Cygwin system packages rather than including Sage-specific copies, including:

  • bzip2
  • libffi
  • libpng
  • patch
  • pcre
  • xz
  • yasm
  • zlib

  We still build our own copies of MPIR and anything that depends on it, as there are still too many bugs with the system GMP on Cygwin.

0.4.3 (2019-05-06)

• Not a change to the installer itself but to the build toolchain, allowing version-specific patches to be applied after a Sage release. From time-to-time critical bugs are found and fixed in Sage only after an official release. And Sage's development process is not quick enough about making new releases. So we add the ability to include post-release patches as needed.

  • Added patch for giac to prevent possible hang in the Sage-Giac interface (https://trac.sagemath.org/ticket/27385).

  • Added several patches for stability in OpenBLAS. Note, however, that the current release does not use OpenBLAS, but rather just uses Cygwin's default BLAS. A future release will switch to OpenBLAS for likely performance gains (https://trac.sagemath.org/ticket/27493 https://trac.sagemath.org/ticket/27509 https://trac.sagemath.org/ticket/27565).

  • Added patch needed for psutil to work with Cygwin 3.0 on which this build is based (https://trac.sagemath.org/ticket/27702).

0.4.2 (2019-02-11)

• Added the m4 and perl packages (and by extension their dependencies) to the runtime environment, since they appear to be needed when installing optional packages.

0.4.1 (2018-09-24)

• Added some dependencies to the runtime environment that were necessary for compiling Cython code at runtime to work (e.g. cython()).

• Improved support for sage -i, at least in principle (not all optional packages work yet, but one can at least install some of the ones that do work).

• Fixed bug preventing sage-sethome from working properly.

0.4 (2018-08-10)

• Added single-user installation mode as the default installation mode--now Sage can be installed without Administrator privileges on the system. Installing Sage with this mode means users can modify files in their Sage installation without Administrator privileges (ideal for tinkering and installing additional packages!)

• Reworked how home directories are handled:

  • Now Sage runs under a single "home directory" that is named /home/sage. For each user, /home/sage actually points by default to their Windows profile directory (i.e. C:\Users\<Username>). This is consistent with previous versions of Sage for Windows, except that /home/sage/ is used instead of /home/<Username>/ where <Username> was your Windows username. This choice is motivated by compatibility with some UNIX software that does not handle spaces or special characters in home directories.

  • It is now possible to change the default home directory used for Sage: For single-user installs you are asked at install time where you would like to set your home directory. However, it can be changed at any time from within the Sage Shell by running sage-sethome [DIRECTORY] where [DIRECTORY] is the Windows path you'd like to set as the home directory for Sage.

• Included ImageMagick in the distribution. This is a dependency of some functionality in Sage, such as for converting LaTeX to PNG images for displaying in the Sage Notebook.

0.3 (2017-12-15)

• Added a license agreement page to the install wizard.

0.2 (2017-08-07)

• Initial version tagged for the SageMath 8.0 release.
