  V1.10 release
  To do/decide:
  * [x] #2557 - **merged**
  * [x] #2745 - needs some tweaks, but we need to decide if it's a good idea before V2
  * [x] #2190 - **deferred**
  * [x] cherry pick stuff from v1.9 branch, maybe just history #4350
  * [x] #3346
  * [x] #3593 -  **deferred**
  * [x] #3946
  * [x] #4028 - **API will change in v2**
  * [x] #4354
  * [x] #4216
  * [x] #4191
  * [x] #3941 - revert or fix
  * [x] #4339
  * [x] #4356
