** 32-bit MS Windows builds have precision problems failing the test suite (bug {{bug|58807}}). Solvable by requiring SSE2 instructions. Go ahead with it.
** possible background: interaction between graphics system and interpreter is different from interaction of rest of GUI with the interpreter. Possibly resolvable by a copy-on-write approach for graphics objects (postponed to Octave 7)

Todays topics

  • Meet and greet 5 minutes before meeting (audio testing).

Octave 6 release status

  • We should create a first release candidate (RC) Octave 6.0.90 soon. Base for discussing and working on further bug findings.
  • Still hard to fix blocking bugs
    • Bug with graphic handles while closing Octave (bug #58814) was reported. This happens when exit is called from a script or when directly calling exit after running the script in the CLI. How to properly handle graphics callbacks during exit?
    • ode15 with Sundials make problems on 32-bit MS Windows builds (bug #58795). Maybe already solved.
