🚀 Kick-off ⚽

⚙️ Update stable and default branch to new version numbers

Completion Date:

  • Merge default onto stable to become the current stable release (see instructions "Merging the default branch to stable before a release" in etc/HACKING.md).
  • Bump version numbers in configure.ac on stable branch (see etc/HACKING.md).
  • Bump version numbers in configure.ac on default branch (see etc/HACKING.md).
  • Create new etc/NEWS.VERSION+1.md file on default branch by copying etc/NEWS.VERSION.md and then removing text so that it is a template file with headings only.

⚙️ Update gnulib to latest version

Completion Date:

Must occur first as it could resolve existing, or create new, bug reports. Run ./bootstrap in the source tree after updating to the new gnulib version.

⚙️ Update Autoconf macros to latest version

Completion Date:

The following Autoconf macros are under version control in the m4 directory. The contents should be verified against the repository at https://github.com/autoconf-archive/autoconf-archive/tree/master/m4. 

   ax_blas.m4
   ax_compare_version.m4
   ax_cxx_compile_stdcxx.m4
   ax_lapack.m4
   ax_openmp.m4
   ax_pthread.m4

The pkg.m4 macro should be verified against the repository at https://github.com/pkgconf/pkgconf/blob/master/pkg.m4.

📢 Call for bug reports

Completion Date:

  • Put out a general call for reports on Octave Discourse for all outstanding, but unreported, known bugs.
  • Create Savannah Release tag VERSION.0.90 on bug tracker for 1st release candidate.
  • Mark items that should be fixed for the release with this tag.
  • Update Savannah Planned Release and Fixed Release fields by adding VERSION.1.0 (current stable) and VERSION+1.1.0 (current default) tags to both.
  • Review bug overview at https://octave.space/savannah/.

📢 Update GUI translation files

Completion Date:

  • Call for updates (Octave Discourse) that might change GUI strings.
  • String freeze date:
  • Update language translation files (*.ts). See instructions in libgui/languages/build_ts/README.md.
  • Create bug report on Savannah as a centralized location for uploading files and tracking status of translations.
  • Call for translations of GUI strings on Octave Discourse Maintainers, CC-ing the translators (see list of translators).
  • Collect translation files on Savannah bug report and push to Mercurial.

⚖️ GPL License activities

Completion Date:

  • Update copyright statements for all source controlled files.
Command to update copyright notifications
hg locate | xargs sed -i 's/Copyright (C) \([0-9][0-9][0-9][0-9]\)-2023 The Octave Project Developers/Copyright (C) \1-2024 The Octave Project Developers/; s/Copyright (C) 2023 The Octave Project Developers/Copyright (C) 2023-2024 The Octave Project Developers/'
Command to check results before checking in
hg diff | grep ^[-+][^-+] | sed 's/[0-9][0-9][0-9][0-9]-/YYYY-/' | sort -u
  • Update dates in any other locations
    • MXE README.html file
    • octave.texi, liboctave.texi, refcard.tex
  • Add any new contributors to doc/interpreter/contributors.in who wish to be mentioned (don’t add them without permission).

✅ Style-check code base

Completion Date:

This will produce lots of whitespace changes, but no behavior changes. Must occur after patches have been added, since whitespace changes can prevent patches from applying.

📖 Review documentation

Completion Date:

  • Grammar check documentation (see doc/interpreter/doccheck/README).
  • Spell check documentation (make spellcheck).
  • Verify no functions missing from manual (make doc/interpreter/undocumented_list).
  • Verify deprecated functions removed from manual (*.txi) and from @seealso links.
  • Verify all formats (Info, HTML, PDF) build correctly.
  • Review etc/NEWS.VERSION.md for any features which should be announced.
  • Review __unimplemented__.m for the latest changes to Octave Forge packages and new Matlab functions.
  • Update installer-files/README.html in MXE Octave with version highlights.

🔃 Repeat until all bugs are resolved

Completion Date of first iteration:

⚠️ Current state at Savannah

Bug overview at https://octave.space/savannah/.

✅ make check

  • Verify make check is passing on all buildbot combinations of OS and compilers and GitHub CI runners. Also check test suite runs on “freshly brewed Octave for Windows” (Kai’s buildbots on octave.space).
  • Use software tools to check quality of Octave code.
    • Check for memory leaks by configuring with --enable-address-sanitizer-flags --disable-visibility-flags --disable-docs --disable-java and compiling with -g -O0 in CFLAGS, CXXFLAGS.
    • Check for bad memory accesses by configuring with --disable-visibility-flags --disable-docs --disable-java and compiling with -g -O0 -fsanitize=undefined -fno-omit-frame-pointer in CFLAGS, CXXFLAGS, and linking with -fsanitize=undefined -fno-omit-frame-pointer in LDFLAGS.
    • Update static code analysis results.
    • Use other tools such as cppcheck, etc.
  • Start discussion on Octave Discourse Maintainers about which failing tests that must be fixed and which can be declared WON’T FIX.

🛠️ Create new release candidate

  • Ensure correct version information (see "Creating first release candidate for new MAJOR version" and "Release Numbering" in /etc/HACKING.md).
  • Verify make dist works.
  • Verify make distcheck passes.
  • Make Windows binaries (see instructions "Make Windows binaries" in etc/HACKING.md).
  • Verify building from a tarball on Linux. Verify that Windows binaries install and run.
  • Create a tag in the Mercurial repository on the changeset where the version number was updated (hg tag rc-MAJOR-MINOR-PATCH).
  • Sign tarballs and binaries with GPG key.
    • Use script build-aux/make-gnu-fist-files to simplify the procedure.
  • Upload release candidates to https://alpha.gnu.org/gnu/octave/.
  • Announce release candidate on Octave Discourse in both Maintainers and Help categories.
