 CHANGELOG
 =========

+0.51.0
+------
+- Added a new environment variable `$FZF_POS` exported to the child processes. It's the vertical position of the cursor in the list starting from 1.
+  ```sh
+  # Toggle selection to the top or to the bottom
+  seq 30 | fzf --multi --bind 'load:pos(10)' \
+    --bind 'shift-up:transform:for _ in $(seq $FZF_POS $FZF_MATCH_COUNT); do echo -n +toggle+up; done' \
+    --bind 'shift-down:transform:for _ in $(seq 1 $FZF_POS); do echo -n +toggle+down; done'
+  ```
+- Added `--with-shell` option to start child processes with a custom shell command and flags
+  ```sh
+  gem list | fzf --with-shell 'ruby -e' \
+    --preview 'pp Gem::Specification.find_by_name({1})' \
+    --bind 'ctrl-o:execute-silent:
+        spec = Gem::Specification.find_by_name({1})
+        [spec.homepage, *spec.metadata.filter { _1.end_with?("uri") }.values].uniq.each do
+          system "open", _1
+        end
+    '
+  ```
+- Added `change-multi` action for dynamically changing `--multi` option
+    - `change-multi` - enable multi-select mode with no limit
+    - `change-multi(NUM)` - enable multi-select mode with a limit
+    - `change-multi(0)` - disable multi-select mode
+- Windows improvements
+    - `become` action is now supported on Windows
+        - Unlike in *nix, this does not use `execve(2)`. Instead it spawns a new process and waits for it to finish, so the exact behavior may differ.
+    - Fixed argument escaping for Windows cmd.exe. No redundant escaping of backslashes.
+- Bug fixes and improvements
+
+0.50.0
+------
+- Search performance optimization. You can observe 50%+ improvement in some scenarios.
+  ```
+  $ rg --line-number --no-heading --smart-case . > $DATA
+
+  $ wc < $DATA
+   5520118 26862362 897487793
+
+  $ hyperfine -w 1 -L bin fzf-0.49.0,fzf-7ce6452,fzf-a5447b8,fzf '{bin} --filter "///" < $DATA | head -30'
+  Summary
+    fzf --filter "///" < $DATA | head -30 ran
+      1.16 ± 0.03 times faster than fzf-a5447b8 --filter "///" < $DATA | head -30
+      1.23 ± 0.03 times faster than fzf-7ce6452 --filter "///" < $DATA | head -30
+      1.52 ± 0.03 times faster than fzf-0.49.0 --filter "///" < $DATA | head -30
+  ```
+- Added `jump` and `jump-cancel` events that are triggered when leaving `jump` mode
+  ```sh
+  # Default behavior
+  fzf --bind space:jump
+
+  # Same as jump-accept action
+  fzf --bind space:jump,jump:accept
+
+  # Accept on jump, abort on cancel
+  fzf --bind space:jump,jump:accept,jump-cancel:abort
+
+  # Change header on jump-cancel
+  fzf --bind 'space:change-header(Type jump label)+jump,jump-cancel:change-header:Jump cancelled'
+  ```
+- Added a new environment variable `$FZF_KEY` exported to the child processes. It's the name of the last key pressed.
+  ```sh
+  fzf --bind 'space:jump,jump:accept,jump-cancel:transform:[[ $FZF_KEY =~ ctrl-c ]] && echo abort'
+  ```
+- fzf can be built with profiling options. See [BUILD.md](BUILD.md) for more information.
+- Bug fixes
+
+0.49.0
+------
+- Ingestion performance improved by around 40% (more or less depending on options)
+- `--info=hidden` and `--info=inline-right` will no longer hide the horizontal separator by default. This gives you more flexibility in customizing the layout.
+    ```sh
+    fzf --border --info=inline-right
+    fzf --border --info=inline-right --separator ═
+    fzf --border --info=inline-right --no-separator
+    fzf --border --info=hidden
+    fzf --border --info=hidden --separator ━
+    fzf --border --info=hidden --no-separator
+    ```
+- Added two environment variables exported to the child processes
+    - `FZF_PREVIEW_LABEL`
+    - `FZF_BORDER_LABEL`
+    ```sh
+    # Use the current value of $FZF_PREVIEW_LABEL to determine which actions to perform
+    git ls-files |
+      fzf --header 'Press CTRL-P to change preview mode' \
+          --bind='ctrl-p:transform:[[ $FZF_PREVIEW_LABEL =~ cat ]] \
+          && echo "change-preview(git log --color=always \{})+change-preview-label([[ log ]])" \
+          || echo "change-preview(bat --color=always \{})+change-preview-label([[ cat ]])"'
+    ```
+- Renamed `track` action to `track-current` to highlight the difference between the global tracking state set by `--track` and a one-off tracking action
+    - `track` is still available as an alias
+- Added `untrack-current` and `toggle-track-current` actions
+    - `*-current` actions are no-op when the global tracking state is set
+- Bug fixes and minor improvements
+
+0.48.1
+------
+- CTRL-T and ALT-C bindings can be disabled by setting `FZF_CTRL_T_COMMAND` and `FZF_ALT_C_COMMAND` to empty strings respectively when sourcing the script
+    ```sh
+    # bash
+    FZF_CTRL_T_COMMAND= FZF_ALT_C_COMMAND= eval "$(fzf --bash)"
+
+    # zsh
+    FZF_CTRL_T_COMMAND= FZF_ALT_C_COMMAND= eval "$(fzf --zsh)"
+
+    # fish
+    fzf --fish | FZF_CTRL_T_COMMAND= FZF_ALT_C_COMMAND= source
+    ```
+    - Setting the variables after sourcing the script will have no effect
+- Bug fixes
+
 0.48.0
 ------
 - Shell integration scripts are now embedded in the fzf binary. This simplifies the distribution, and the users are less likely to have problems caused by using incompatible scripts and binaries.
