New indicators:

Minor breaking change:

- Moved extra SMA analysis to new variant: `GetSmaExtended`. If you were using the `extended=true` parameter value in `GetSma`, you'll have to update the reference to the new separate extended method. See [more info](https://github.com/DaveSkender/Stock.Indicators/discussions/320#discussioncomment-324365) on this new convention to separate concerns.

Chores:

- Added GitHub lockbot to lock old closed issues and pull requests. Apologies for the spam notifications while that process caught up, for those of you who were watching the repo. It is caught up now.
- Update documentation

New minor feature:

- add IDE inline tooltip information with links to online documentation (e.g. in Visual Studio), example:


Chores:

- increase the history threshold for SuperTrend to match the underlying ATR threshold
- update code analysis and misc code cleanup
- update documentation
- remove internal use of GitVersion in build

New minor feature:

- add [KDJ Index](https://daveskender.github.io/Stock.Indicators/indicators/Stoch/#content) as an extension of Stochastic Oscillator
