0.62.0

Test cases:

1. 'jump' should show alternating background colors even when 'alt-bg' is
not defined as before.

  go run main.go --bind load:jump

Two differences:
  * The alternating lines will not be in bold (was a bug)
  * The marker column will not be rendered with alternating background color

2. Use alternating background color when 'alt-bg' is set

  go run main.go --color bg:238,alt-bg:237
  go run main.go --color bg:238,alt-bg:237 --highlight-line

3. 'selected-bg' should take precedence

  go run main.go --color bg:238,alt-bg:237,selected-bg:232 \
                 --highlight-line --multi --bind 'load:select+up+select+up'

4. Should work with text with ANSI colors

  declare -f | perl -0777 -pe 's/^}\n/}\0/gm' |
    bat --plain --language bash --color always |
    go run main.go --read0 --ansi --reverse --multi \
                   --color bg:237,alt-bg:238,current-bg:236 --highlight-line

 CHANGELOG
 =========
 
+0.62.0
+------
+- Relaxed the `--color` option syntax to allow whitespace-separated entries (in addition to commas), making multi-line definitions easier to write and read
+  ```sh
+  # seoul256-light
+  fzf --style full --color='
+    fg:#616161 fg+:#616161
+    bg:#ffffff bg+:#e9e9e9 alt-bg:#f1f1f1
+    hl:#719872 hl+:#719899
+    pointer:#e12672 marker:#e17899
+    header:#719872
+    spinner:#719899 info:#727100
+    prompt:#0099bd query:#616161
+    border:#e1e1e1
+  '
+  ```
+- Added `alt-bg` color to create striped lines to visually separate rows
+  ```sh
+  fzf --color bg:237,alt-bg:238,current-bg:236 --highlight-line
+
+  declare -f | perl -0777 -pe 's/^}\n/}\0/gm' |
+    bat --plain --language bash --color always |
+    fzf --read0 --ansi --reverse --multi \
+        --color bg:237,alt-bg:238,current-bg:236 --highlight-line
+  ```
+- [fish] Improvements in CTRL-R binding (@bitraid)
+    - You can trigger CTRL-R in the middle of a command to insert the selected item
+    - You can delete history items with SHIFT-DEL
+- Bug fixes and improvements
+    - Fixed unnecessary 100ms delay after `reload` (#4364)
+    - Fixed `selected-bg` not applied to colored items (#4372)
+
+0.61.3
+------
+- Reverted #4351 as it caused `tmux run-shell 'fzf --tmux'` to fail (#4559 #4560)
+- More environment variables for child processes (#4356)
+
+0.61.2
+------
+- Fixed panic when using header border without pointer/marker (@phanen)
+- Fixed `--tmux` option when already inside a tmux popup (@peikk0)
+- Bug fixes and improvements in CTRL-T binding of fish (#4334) (@bitraid)
+- Added `--no-tty-default` option to make fzf search for the current TTY device instead of defaulting to `/dev/tty` (#4242)
+
 0.61.1
 ------
 - Disable bracketed-paste mode on exit. This fixes issue where pasting breaks after running fzf on old bash versions that don't support the mode.
