libmutton v0.5.0 Release date TBD

This release adds password age-tracking support and features large refactors that improve the robustness of core functionality. Many breaking changes are present. Highlights are listed below.

Breaking (for users+developers)

• USERS: These changes require updating your copy of libmuttonserver; additionally, you must re-generate your config file however your client allows (e.g. mutn init)
• (50d51f9d96) Password age tracking support
  • libmutton now tracks when passwords were last updated
  • Clients can use this information to warn users when passwords should be changed
  • Random (within the last year) age data can be added to existing password entries
    • This allows easing into this feature, rather than having all your passwords expire on the same day
  • Developers: see the new age package
• (e355c810da) (f16078fe01) (4e6c18db8a) (2ab777fd57) (941a2dc8b8) (35db3bf20b) (5e5a7c57e9) (07571a698d) (d0e8640ce6) (3b4e75b592) Massive sync refactor
  • Sync info is now passed from the server to the client using rigidly defined JSON types
    • This greatly improves code maintainability and reduces potential for bugs
  • Sync now supports password age tracking data
• (b591e2ef5a) (571bc0a3bd) New config file format
  • libmutton.ini is now libmuttoncfg.json
    • This format change was made since the JSON package was being adopted for the sync refactor (the gopkg.in/ini.v1 dependency can now be dropped)
  • Developers: see the new config package, replacing the old cfg package

Breaking (for developers)

• (bf1399ce8d) (9703790336) (a0f21b31f7) (80cf65775a) (8d1dd48035) (c63dff4092) (336dc5c158) (04e1b0dd37) (d2a6ed5eaa) (fdce036be6) (6004a94b77) Massive clipboard refactor
  • Added new clip package
  • Non-continuous TOTP copy must use core.GenTOTP directly
    • The typical copy workflow now only supports continuous copy
  • Dropped mobile clipboard support
    • This can/should be handled by the GUI toolkit
• (28286788a0) (a18c3ea1d6) (5e5a7c57e9) (4467a8c742) core.LibmuttonInit overhaul
  • Now supports non-destructive append
  • Now supports custom device ID prefixes
