+## Publications
+
+- MDRange optimization paper consideration for SC workshops
+- Possible papers we could focus on
+  - New Kokkos ecosystem paper mentioning new efforts and the transition to HPSF
+    - waiting for Comm blog post, and maybe Fortran Interop
+  - Maybe a paper to describe how Kokkos is evolving in response to the unified memory advent (APUs, HMM, etc.)
+- Technical blog posts
+
+## Bigger discussions
+- backend-specific properties:
+  - [6496](https://github.com/kokkos/kokkos/pull/6496): SYCL: Allow setting subgroup size
+- memory space design:
+  - [6835](https://github.com/kokkos/kokkos/pull/6835): Remove MemorySpace::[de]allocate overloads without labels
+  - [6918](https://github.com/kokkos/kokkos/issues/6918): kokkos_malloc should accept an execution space instance
+- Rethink the containers: They were designed in another age and it would be good to revise/rethink them. This might be a discussion for the time of v5-v6.
