- Optimized/Customized/Catregorize -> Optimised/Customised/Categorise
- Github -> GitHub (80% were spelt with capital H, this is the way GitHub spells itself)
- GitPod -> Gitpod (most were without the capital P, Gitpod's site does not use capital P)
- Remove duplicate words (to to, the the)
- De-coupled -> decoupled
- implementors -> implementers (all other references used 'site implementers' so just aligning with the common case)
- Fix a/an usage in one case
- Fix one comment usage of ok, replace with OK
Reorganise the 4.2 release notes and changelog to include new sections for documentation and maintenance. This helps to highlight the most relevant changes from the perspective of a developer wanting to know what they can expect from an upgrade, while still recognising less visible contributions. Also update the "committing code" docs to explain the new classification scheme.
