+## Last Week's Minutes
+
+* Announcements
+    * None this week
+* embedded-hal
+    * Invert layout of traits? https://github.com/rust-embedded/embedded-hal/pull/298
+        * There was some worry that this would result in lots of copies of a module named `blocking` in scope due to e.g. `use e_h::spi::blocking`, but perhaps in practice users would either `use e_h::spi` and then bound `T: spi::blocking::Write`, or just use the trait directly.
+        * This also allows shared items such as Errors to go into the top-level modules.
+    * Associated Word types https://github.com/rust-embedded/embedded-hal/pull/295
+        * Lots of discussion happening on the PR thread, so no further discussion in meeting this week.
+    * Remove the various Default traits: https://github.com/rust-embedded/embedded-hal/pull/289
+        * Consensus seems to be for removal.
+    * Any other PRs?
+* cortex-m
+    * PR for 0.6.15 and 0.7.0: review from cortex-m team?
+* showcase
+    * Needs updating to use GHA, @adamgreig to do after meeting
+* blog
+    * Blocked on posting for help with cross maintainership, hopefully real soon now
