 - Exposes both the our classic API (e.g. `dss.v7.DSS_IR` for the immediate/direct results) and global result API (e.g. `dss.v7.DSS_GR` for the global result interface). See [DSS C-API's docs](https://github.com/PMeira/dss_capi/blob/master/docs/usage.md) for a detailed explanation. We default to the GR interface since it will generally be faster at the cost of a small memory overhead.
 - Although still experimental, the v8/PM module is more stable. If you try it, please give feedback.
 - Error checking is now done for most API writes. That is, if a an OpenDSS error occurs, it should cause a Python exception soon after. Previously, you need to call `CheckForError()` manually to trigger this. This change was introduced after user reports indicated that manually checking for errors is a common behavior.
-- Expose API extensions for the classes `LineGeometry`, `WireData`, `LineSpacing`, `CNData`, `TSData`, `Reactor`.
-- Make most DSS classes iterable (including buses), e.g. you can now use:
