v2.5.0-beta.1

Breaking changes

This is a beta pre-release of a minor bump. v2 still accepts planned API breaks. Apps that compiled against 2.4.17 may need source changes.

1. View.Text is no longer virtual (#5371 / #5366)

   • Use OnTextChanging(string proposedValue) / TextChanging to validate or cancel.
   • Use OnTextChanged() for post-change sync.
   • TextField uses View.Text directly (no new hider).

2. IAcceptTarget moved to Terminal.Gui.Input (#5395 / #5369)

   • Add using Terminal.Gui.Input;.

3. Legacy ConfigurationManager removed (#5416 / #4367)

   • Replacement: TuiConfigurationBuilder and Settings POCOs (ButtonSettings.Current, etc.).
   • config.json is nested only. Convert old flat-key files with Tools/MigrateConfig.
   • Types marked [Obsolete] in 2.4.17 (#5411) are gone.

See Breaking changes 2.5.0 and Migrating ConfigurationManager to TuiConfigurationBuilder.

Highlights

• Editable NumericUpDown
• TableView horizontal scrolling for wide content
• Native ANSI size detection; platform detection cleanup
• SynchronizationContext fix
• Kitty protocol: preserve repeated legacy input after detection
• DropDownList: hide active popover on DeRegister (stale cells, #5635)
• NativeAOT: RuneJsonConverter no longer trips IL2026
