• @tarikguney (Tarik Guney) contributed five PRs fixing paste freeze regressions, pane-died/pane-exited hooks with remain-on-exit, the bounded frame channel that preserves fast typing, the list-panes -s multi-window iteration bug, and the switch-client routing fix. An extraordinary volume of high-quality work.
• @pbolduc (Phil Bolduc) contributed the new-session -e environment variable support and case-insensitive username/path comparison improvements, in addition to filing six detailed bug reports that drove major fixes.
• @ohboyftw (Aravind) fixed the bounded frame push that was causing a copy-mode scroll memory leak.
• @jun2077681 (hasu) contributed the scroll_pane_scrollback approach that landed as a core scrollback improvement and co-authored the pwsh-mouse-selection feature.
• @wosuxiongmao (House) fixed run-shell executables not resolving to absolute paths on Windows.
• @sepiabrown (Suwon Park) fixed bind-key new-window -c silently dropping the -c start directory flag.
• @ToxMox (Dave) fixed mouse coordinate alignment for multi-client sessions.
• @leotorrez (Leandro Torrez) updated documentation links.
• @XingLingQAQ contributed focus preservation when killing targeted panes and configurable detach and empty-exit policies.
