- [ ] **ND**: Look at DIALS failures and work out what needs to be migrated
- [x] Has been movement as DGW started investigating: https://github.com/dials/dials/pull/2465
- [ ] **AB**: Check test case on Multidimensional Images [dxtbx#612](https://github.com/cctbx/dxtbx/pull/612) is reasonable
- [ ] **DP**: Add msgpack "hot" path to include environment in cctbx ([prev](https://dials.github.io/kb/core/2023-05-04#msgpack-httpsgithubcomdialsdialspull2409))
- [ ] Work in https://github.com/cctbx/cctbx_project/commit/03a9a6797044126984a69ff30d00be6df408e43a, pending approval/merge
- [ ] [not until august at least] **JBE:** Solve "multiplex: Duplicate Batch offsets detected" [xia2#430](https://github.com/xia2/xia2/issues/430) ([prev](https://dials.github.io/kb/core/2023-06-15#xia2multiplex-fails-because-duplicate-batch-offsets-detected))
- [ ] **AB**: Check if RG test cases on [dxtbx#612 "Multidimensional Images"](https://github.com/cctbx/dxtbx/pull/612) are appropriate
- [ ] A dependency of [dxtbx#615 NX Writer](https://github.com/cctbx/dxtbx/pull/615) ([prev](https://dials.github.io/kb/core/2023-06-15#nx-writer-prev-prev)) so promote this to agenda again when done
- **AB**: Moving forward serialtbx changes ([prev](https://dials.github.io/kb/core/2023-06-15#removing-circular-xfel-dependencies-with-serialtbx)). [cctbx#872](https://github.com/cctbx/cctbx_project/pull/872) seems immediate blocker.
