+
+## Last Week's Agenda
+
+* Mutex Trait Naming
+    * Consensus on naming: `mutex-trait`
+* https://github.com/rust-embedded/embedded-hal/issues/156
+    * Suggestion to base this on musca-b1 because it's shiny and new and Cortex-M33
+* https://github.com/rust-embedded/embedded-hal/pull/171
+    * Discussion about whether it's a good idea to use the heavily async-await based contract `core::task::Poll` instead of `nb`
+        * Pro: Use of core components instead of custom crates
+        * Con: Maybe not ideal for non-async use cases
+        * Needs a RFC for experimentation and comments
+*  CONTROL::FPCA register - add reset method to cortex-m? (See https://static.docs.arm.com/ddi0403/eb/DDI0403E_B_armv7m_arm.pdf page 575)
+    * Shouldn't require much discussion, can be added with a PR to cortex-m
+* Meeting agenda for next week, back to using agenda tracking issues:
+    * https://github.com/rust-embedded/wg/issues/398
+* https://github.com/rust-embedded/cortex-m-rt/issues/212
+    * Requires a new release to fix soundness issue
+        * Consensus on releasing as a ~minor~ patch release (v0.6.x) potentially causing breakage upon abuse of the unsoundness
+        * No consensus on yanking older versions of 0.6
+        * As a bonus: New release will yield reproducible builds
+
+## Last Week's Action Items
+
+* [ ] @jamesmunns to write a proposal about a monorepo for books (still todo)
+* [ ] Someone to add "update your cortex-m-rt" with instructions to the blog posts
