It's been a few weeks since the last release, and much has changed in the main branch. This issue is to track what still needs to be done before 0.4.17 0.5.0 release:

• [x] Documentation examples need to be updated and recomputed (#168 )
• [ ] #154 needs to be documented
• [ ] #150 needs to be documented
• [ ] #148 needs to be documented (debug toolkit)
• [ ] #157 needs to be documented
• [ ] #141 needs to be documented
• [ ] #158 needs to be documented (breaking change)
• [ ] #109
• [ ] #156
• [ ] #161 needs to be documented
• [x] #160
• [ ] #110
• [ ] #166

Considering we are including breaking changes, we should release this as 0.5.0.
