Announcements

New format for weekly meetings?
- Try out a sort of "impl meeting" occasionally (every other week? every month?) where we
  plan to actively work on things in the meeting time instead of purely discussing
- Try out github discussions to have a per-week topic to collect things to discuss/talk about
  - For example https://github.com/esp-rs/rust/discussions
- Resume use of nominated label
- Potential topics for next week:
  - SPI trait documentation: how and when to share the SpiBus
  - Better Delay provider in cortex-m (can be cloned, using either asm::nop or SysTick?)
  - c-m-interrupt-number/c-m-pac-interface
  - update discovery and/or book tooling pages to mention probe-rs instead of openocd
  - deprecate and archive mutex-trait
  - perhaps swap cortex-m back to 0.7 by reverting the 0.8 breaking change and get a 0.7 release out
