Release highlights: https://junegunn.github.io/fzf/releases/0.71.0/

• Added --popup as a new name for --tmux with Zellij support
  • --popup starts fzf in a tmux popup or a Zellij floating pane
  • --tmux is now an alias for --popup
  • Requires tmux 3.3+ or Zellij 0.44+
• Cross-reload item identity with --id-nth
  • Added --id-nth=NTH to define item identity fields for cross-reload operations
  • When a reload is triggered with tracking enabled, fzf searches for the tracked item by its identity fields in the new list.
    • --track --id-nth .. tracks by the entire line
    • --track --id-nth 1 tracks by the first field
    • --track without --id-nth retains the existing index-based tracking behavior
    • The UI is temporarily blocked (prompt dimmed, input disabled) until the item is found or loading completes.
      • Press Escape or Ctrl-C to cancel the blocked state without quitting
      • Info line shows +T* / +t* while searching
  • With --multi, selected items are preserved across reload-sync by matching their identity fields
• Performance improvements
  • The search performance now scales linearly with the number of CPU cores, as we dropped static partitioning to allow better load balancing across threads. === query: 'linux' === [all] baseline: 21.95ms current: 17.47ms (1.26x) matches: 179966 (12.79%) [1T] baseline: 179.63ms current: 180.53ms (1.00x) matches: 179966 (12.79%) [2T] baseline: 97.38ms current: 90.05ms (1.08x) matches: 179966 (12.79%) [4T] baseline: 53.83ms current: 44.77ms (1.20x) matches: 179966 (12.79%) [8T] baseline: 41.66ms current: 22.58ms (1.84x) matches: 179966 (12.79%)
  • Improved the cache structure, reducing memory footprint per entry by 86x.
