+
+![](https://github.com/user-attachments/assets/9640ae11-b5f7-43fb-95f1-c29307fc17c2)

 This version introduces a new "raw" mode (named so because it shows the list
 "unfiltered"). In raw mode, non-matching items stay in their original positions,
-but appear dimmed. This allows you see surrounding items of a match and better
-understand the context of it. You can enable raw mode by default with `--raw`,
-but it's often more useful when toggled dynamically with the `toggle-raw`
-action.

-### Added key support for `--bind`
+#### `$FZF_SOCK`

-Pull request #3996 added support for many additional keys for `--bind` option,
-such as `ctrl-backspace`.
+When fzf is listening on a Unix domain socket using `--listen`, the path to the
+socket is exported as `$FZF_SOCK`, analogous to `$FZF_PORT` for TCP sockets.

-### Breaking changes
+#### `$FZF_RAW`
+
+As described above, `$FZF_RAW` is now exported to child processes in raw mode,
+indicating whether the current item is a match (`1`) or not (`0`). It is not
+defined when not in raw mode.
+
+#### `$FZF_CTRL_R_COMMAND`
+
+You can opt-out `CTRL-R` binding from the shell integration by setting
+`FZF_CTRL_R_COMMAND` to an empty string. Setting it to any other value is not
+supported and will result in a warning.
+
+```sh
+# Disable the CTRL-R binding from the shell integration
+FZF_CTRL_R_COMMAND= eval "$(fzf --bash)"
+```

Koichi Murase	5cb695744f	[bash,zsh] Fix the version check for mawk (#4574 ) We have been checking the mawk version by extracting <x>, <y>, <z>, and <d> part from "mawk <x>.<y>.<z> <d>" in the output of the "mawk -W version" and testing <x>, <y>, <z>, and <d> using an arithmetic evalaution. However, <d> is ensured to be an integer only in "x.y.z >= 1.3.4". Otherwise, it may cause a syntax error in the arithmetic evaluation. The mawk started to include the date as an integer in the <d> position only from mawk-1.3.3-20090721. We should first check that "x.y.z >= 1.3.4" and then check the value of "d". In case, "mawk -W version" produces a completely different text, we should also redirect stderr of the arithmetic commands to /dev/null.	2025-10-31 21:14:41 +09:00
