The previous release contained a regression that made the nRF DeviceTree extension's autocompletion take several seconds. Parsing and linting was also affected by this regression, causing severe performance issues in both startup time, autocompletion, and syntax validation.
The underlying regression has been addressed, along with some related performance bottlenecks. Startup, parsing, and autocompletion should now take less than 50 ms, even for large devicetrees.
