• Improvements to various documentation pages (#3587, #3526)
• Fixed CMake configuration errors that prevented successfully building on Windows when the project path contains spaces (#3525).
• Fixed PSinGrain growing in amplitude after it was supposed to finish (#3494).
• sclang now creates a configuration directory on startup, rather than waiting for it to be created by another action. This step is skipped if sclang is run as a standalone (-a) or if a language config file is specified with the -l option (#3577).
• SequenceableCollection:unixCmd now allows respects PATH instead of strictly requiring the executable path (#3501).
• A new method, Platform:killProcessByID, was added (#3499).
• LanguageConfig:store throws an error if it fails to write (#3577).
• Fixed an off-by-one error in a warning message for Server:clientID_ (#3487).
• Event:isRest now returns true if the event’s \isRest entry is true. This usage was backported from 3.8 and is deprecated (#3521).
• Server now tries to recover in the case of a lost connection between client and server (#3486).
• Fixed an error when producing a Score containing an Event with a multichannel timingOffset (#3544).
• The help browser table of contents popout no longer has redundant “table of contents” text (#3576).
