PopulationSim

• open PRs and issues:
  • #219 deps and cross platform diffs one unresolved comment
  • #221 max hh weight cap more problems?

Other

• Joint MoMo submission?
• There has been a (re)request to make a release from main ASAP to support consortium members moving forward with models that depend on unreleased features. Definitely #1001 PnR should get merged before we do so. Any other open PRs that the team feels a need to wait for? (We can do a release very soon and another at the end of Phase 11, so we should not wait just for completeness)
