v3.4

It's been the better part of a year since v3.3, and v3.4 is a big one: new features across the board, a thorough pass on markup rendering, and dozens of bugfixes.

Highlights:

• Search highlighting (hlsearch): every match for / and g/ is now highlighted in place; toggle with options.highlight_search. (#2861)
• Human-readable keys everywhere: the "prettykeys" overhaul means all bindings display with readable names (Ctrl+Up, Alt+d, …) in help, menus, and status. (#2594)
• Smarter -f: filetype now separated between input and output, with -f for the input filetype, and -of for the output filetype, which supports compound format+compression types like json+gz; an explicit -f also overrides URL-scheme dispatch.
• Define your own commands in-session: define-command <longname> <execstr>, with currow.<ColName> available to read the cursor row's values. (#655)
• Save edited options straight to your config with z Ctrl+S. (#2206)
• Split-pane file preview on the DirSheet. (#3024)
• Customizable cell-editing keys via vd.editCellBindings. (#2986)
• Jump to any sheet by name with jump-sheet (with tab-completion).
• Change displayed float precision with setcol-precision (Alt+-/Alt++/g%).
• Drop into an interactive $SHELL with exec-shell.
• Aggregation bar showing aggregate totals. (#2209 #2995)
• Fuzzy input-history palette. (#2684)
• Macros now support keystroke bindings and input parameters. (#2784 #2785)
• Smarter SQLite exec-sql: named queries, types, and edit-sql. (#2136 #3020)
• GeoParquet support: decode WKB geometry and plot it.
• vdsql improvements: multi-schema browsing (#2027) and SQL shown in the sidebar (#2200).
• S3 recursive directory listing and anonymous-mode access.
• Better HTML tables: handle interspersed th/td and rowspan. (#1346 #1308)
• CSV now skips blank lines. (#3085)
• New adwaita light and dark themes. (#3006)
• An embedded ptipython REPL. (#2736)
• A command server for scripting VisiData.
• Experimental: vdaw, a transcript-based audio editor.
• Experimental: an llm plugin to analyze columns with Anthropic Claude. (#2947)
• Experimental: search_geo, bbox-overlap helpers for STAC catalogs.
