New Features:

  • Show Dual/Triple Serial Teensy builds as multiple boards

Other changes:

  • Add TyCommander upload --delegate to cooperate with Teensy Loader
  • Fix support for composite devices on Windows 7 (e.g. Serial + MIDI)
  • Remove all Windows XP compatibility code

Previous release builds did not actually work on Windows XP, but the code for it was still there. Now it is official, and it is not possible to build TyTools or libhs with XP support anymore.

New Features:

  • Detect running Teensy model with bcdDevice descriptor value (introduced in Teensyduino 1.42)
  • Add @-prefixed commands 'send_file' and 'send' to TyCommander serial input
  • Support loading firmwares from stdin in tycmd upload and tycmd identity

Main Fixes:

  • Fix errors with Teensy 3.5 firmwares (caused by 'RAM = 256K' change introduced Teensyduino 1.42)
  • Fix rare Intel HEX parse errors

Note: This is the mostly the same as 0.8.9 except this time the macOS version works. For Windows and Linux users, nothing has changed (except the version number).
