6:21 Core

Overall: Things are looking good. Will be digging into the 7.0.0 milestone to decide which issues we want to fix for 7.0.0 and which we’ll wait on. We hope to drive down the bug count so we can release 7.0.0 stable relatively soon.

8:05 Libraries

Library updates in the last seven days:

Updated Libraries

Overall: We’re trying to get through all the open PRs - Jose David has his eye on everything currently open but require discussion to determine what to do based on suggestions from Jose David. Thanks to everyone who has been contributing to the libraries!

17:43 Status Updates

18:15 @jepler

  • Last week:
    • Substantially completed the OV2640 library
    • Merged micropython 1.16 (PR is ready for review)
    • Implemented Dan’s (or maybe Scott’s) idea of reduced size of core property objects, but net savings was rather small, and it probably decreases performance, so we’ll probably leave it out for now. (PR is on github)
    • Implemented Dan’s idea of “split up” type structures for core types. Saves 1.5kB but requires more discussion (including with micropython and ulab) even if we decide we want to take it. Need to benchmark whether it affects speed. (PR is on github)
  • This week:
    • Finishing up the OV2640 library & adding to bundle
    • Writing a guide covering the OV2640 and OV7670 cameras in CircuitPython
    • Start working on a project for an upcoming guide. I’m excited to do a project guide again, it’s been awhile!
