• High-performance generation of word-processing documents, spreadsheets, and presentations.
• Document modification, such as adding, updating, and removing content and metadata.
• Search and replace content using regular expressions.
• Splitting up (shredding) a file into multiple files, and combining multiple files into a single file.
• Updating cached data and embedded spreadsheets for charts in Word/PowerPoint. 

• Fixes issue when entering wrong credentials while trying to connect to a remote Mac build host.
• Fixed an inability to open some types of files.
• Fixed an issue resulting in a failure to add an Apple Developer account with two-step authentication.
• Fixed a crash in watchOS applications when creating GC thread.
• Fixed regression that disallowed exponential floats of the form 1e5f.
• Fixed an issue preventing opening files that are opened in external applications such as Word or Excel.
