• generalized parameter passing of el.datastore.File and el.datastore.specialized_file
• added el.widgets.value_box.ValueBox
• added module el.datastore.savable
• renamed el.datastore.set_datastore_base_path to el.datastore.set_datastore_root to prevent confusion with specialized_file's base path
• added module el.nixos_ctk_font_fix
• added support for connecting el.terminal.TerminalController to non-ttys.
  • Interactivity (prompt, command handling) will now automatically be disabled when connecting stdin to a non-tty (e.g. when using .desktop files or cron jobs) instead of the application crashing.
• added module el.tkml: Tkinter wrappers to build UIs more easily using a declarative ish "markup language" using context managers
  • el.tkml.adapters contains adapter functions to integrate legacy tkinter widgets and variables
  • el.tkml.pack contains a pack wrapper
  • el.tkml.grid contains contextual or layout-based grid wrappers to simplify developer experience
• added el.timers.WDTimer.active property
• added el.observable.filters.throttle and a new StatefulFilter API to implement it and similar time-based filters
• added el.lifetime: A system to manage Callback and observable lifetimes using a LifetimeManager:
  • This system currently works for el.callback_manager.CallbackManager and el.observable.Observable
  • With this change, el.callback_manager.CallbackID has been removed and is to be replaced with el.lifetime.RegistrationID
  • The system is extensible, other registries can be managed as well by implementing el.lifetime.AbstractRegistry
• el.observable.filter.call_if_true() now supports a False case
• added MaybeObservable type and the accompanying functions maybe_observe and maybe_obs_value to el.observable
• el.observable.Observable.observe() now has a flag to disable initial updates
• added module el.widgets.ctkex: A collection of CTk Widgets with extended functionality such as touchscreen mode. (Unlike other el.widgets, these are not new, specialized widgets, but just regular CTk widgets with some additional functionality)
  • option to selectively disable corner rounding on CTkEntryEx and CTkButtonEx
  • patched support for background_corner_colors, round_height_to_even_numbers, round_width_to_even_numbers arguments (from CTkButton) into CTkEntryEx
• added spinbox.SpinBox to el.widgets
  • configurable increments and formatting
  • text input and button input possible
  • configurable text/icons on buttons
  • child-widgets exposed for further customization
  • observable

Some of the changes are breaking and some functions have been renamed. Before updating to this version, keep in mind that you may need to perform some migrations in the codebase.
