## Summary:

                 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
                  CORFU.EL - COMPLETION IN REGION FUNCTION
                 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━


  Corfu enhances in-buffer completion with a small completion popup. The
  current candidates are shown in a popup below or above the point. The
  candidates can be selected by moving up and down. Corfu is the
  minimalistic in-buffer completion counterpart of the [Vertico]
  minibuffer UI.

                          CORFU.EL - CHANGELOG
                         ━━━━━━━━━━━━━━━━━━━━━━





1 Development
═════════════

  • Preserve currently selected candidate on further input. This matters
    if candidate preview is disabled (`corfu-preview-current=nil').
  • Add new command `corfu-expand' bound to `M-TAB' by default. The
    command expands the input via `completion-try-completion', for
    example the `basic' completion style expands the common prefix of
    all candidates.


2 Version 1.2 (2024-01-23)
══════════════════════════

  • Support the EXWM window manager.
  • Optimization: Reduce auto completion timer overhead.
  • Use `internal-border-width' instead of `child-frame-border-width'.
  • Internal refactoring: Do not use buffer-local variables.
  • Internal refactoring: Store `completion-extra-properties' as part of
    `completion-in-region--data'.


3 Version 1.1 (2023-12-27)
══════════════════════════

  • Deduplicate candidates with respect to `equal-including-properties',
    such that backends can provide equal candidate strings, which only
    differ in their text properties and annotations.
  • Ensure that the string passed to the `:exit-function' retains the
    candidate properties, when possible. The properties are guaranteed
    to exist when a candidate is selected explicitly, but may be missing
    when candidates are completed in a stepwise manner.
  • `corfu-on-exact-match': Add value `show' to the customization
    option. With this setting the Corfu popup will be shown even if
    there is only a single matching candidate.


4 Version 1.0 (2023-12-01)
══════════════════════════

  • Bug fixes.
  • `corfu-quick': Use a slightly different scheme to support more
    candidates.
  • `corfu-reset': Quit immediately if input did not change.
  • Support `completion-lazy-hilit'.


5 Version 0.38 (2023-08-14)
═══════════════════════════

  • `corfu-quick': Bugfix.
  • `corfu-mode-map': Add mode map.
  • Replace `corfu-excluded-modes' with `global-corfu-modes', the Emacs
    28 convention for globalized minor modes.


6 Version 0.37 (2023-07-02)
═══════════════════════════

  • Bugfixes.
  • Improve child frame display code, `corfu--popup-show' takes a `posn'
    argument.
  • Ensure that the popup font matches the font of the parent frame.
  • Close popup when window selection changes.
  • Remove `corfu-history-length'. Instead set the `history-length'
    property of `corfu-history' variable.
  • `corfu-info-documentation', `corfu-info-location': Make buffer and
    window persistent if called with prefix argument.


7 Version 0.36 (2023-03-27)
═══════════════════════════

  • Drop obsolete `corfu-preselect-first'.
  • `corfu-popupinfo-delay' and `corfu-echo-delay': Remove support for
    value `t'.  Instant updates are not recommended. It is still
    possible to use a small value for the delay.
  • Rename `corfu-excluded-modes' to `corfu-exclude-modes' (Naming
    convention).
  • Remove call to `undo-boundary', which caused issues with auto
    completion.


8 Version 0.35 (2023-02-17)
═══════════════════════════

  • `corfu-popupinfo': Take more text into account when computing popup
    width.
  • `corfu-popupinfo': Change keybindings, remap
    `corfu-info-documentation/location'.
  • `corfu-popupinfo': Add commands `corfu-popupinfo-beginning/end'.
  • `corfu-popupinfo': Improve popup placement.
  • Add `corfu-prompt-beginning' and `corfu-prompt-end' commands.
  • Add `corfu-preselect' option, deprecate `corfu-preselect-first'.
  • Use `cl-defgeneric' internally as mechanism to allow extensions to
    override functionality, e.g., the candidate formatting and display.


9 Version 0.34 (2022-12-03)
═══════════════════════════

  • Bugfixes
  • Popup frame code updated for Emacs 29. Please report any issues.
  • `corfu-popupinfo-direction': Variable must be a list of directions.
  • Support height adjustments of `corfu-default' face


10 Version 0.33 (2022-11-21)
════════════════════════════

11 Version 0.31 (2022-11-20)

13 Version 0.29 (2022-11-19)
════════════════════════════

  • BREAKING: Extract the `corfu-echo' extension from `corfu.el'. In
    order to see echo messages, enable `corfu-echo-mode'. You probably
    want to enable either `corfu-echo-mode' or `corfu-popupinfo-mode'.
  • BREAKING: Rename `corfu-echo-documentation' to `corfu-echo-delay'.
