* Octave 7.2 has been released
* VM activities:
** Configure switches to enable/disable compiling the VM have been added.
** No actual VM code has been pushed so far. It needs to be rebased on a (more) current head.
* Transition to Fosshost:
** The buildbot server has been moved from the Digital Ocean server to Fosshost. The Digital Ocean server will be retired.
** The new buildbot server URL is [https://buildbot.octave.org https://buildbot.octave.org] (without explicitly specifying a port). Documentation still referring to the URL with the port number might need to be updated.
** The Fosshost server is periodically mirrored to the Dreamhost server. This is likely to stay that way unless someone complains.
* shadowing of core functions from statistics package
** Packages should try to avoid shadowing core functions as far as possible.
** As a "compromise" to make newer features available to older Octave versions, packages could conditionally shadow core functions depending on version numbers. See, e.g., [https://octave.discourse.group/t/new-maintainer-for-the-statistics-package/2791/83?u=mmuetzel] for a possible approach.

Today's topics[edit]

  • Octave 7.2 has been released
  • VM activities:
    • Configure switches to enable/disable compiling the VM have been added.
    • No actual VM code has been pushed so far. It needs to be rebased on a (more) current head.
  • Transition to Fosshost:
    • The buildbot server has been moved from the Digital Ocean server to Fosshost. The Digital Ocean server will be retired.

  • shadowing of core functions from statistics package
    • Packages should try to avoid shadowing core functions as far as possible.
    • As a "compromise" to make newer features available to older Octave versions, packages could conditionally shadow core functions depending on version numbers. See, e.g., [1] for a possible approach.
  • GSoC activities
    • Haven't been discussed.
