What's new

Major features and improvements in each release.

v1.9.5LatestJuly 10, 2026

Long-run stability & smarter suggestions

  • Cleaner serial command suggestions — inline ghost-typing on serial sessions now renders as a non-destructive overlay, so suggestions never overwrite real output or leave gray residue behind
  • Magic Input stays out of your way — the "@" trigger no longer collides with full-screen apps like Claude Code, vim, or less, and you can now choose your own trigger character and when it activates
  • Fixed long-run text corruption — emoji and CJK text no longer garble after hours of use; the glyph-cache refresh was re-landed safely, without the split-pane regression it caused before
  • GPU re-enable now recovers every session — turning GPU acceleration back on after a rendering fault un-bans all sessions, not just the focused one
  • Lower CPU on busy sessions — terminal data now travels over a single streamlined path instead of being encoded and sent multiple times per byte
  • Steadier memory on marathon sessions — background sessions no longer stall the read loop, and per-session scrollback can shrink back down instead of only growing
v1.9.4June 23, 2026

UI polish & rendering stability

  • Right-click menu stays on screen — opening the terminal context menu near the bottom edge no longer pushes the Paste option off-screen, and the Paste row now shows its Ctrl+V / ⌘V shortcut
  • Saved Profiles list fits any window — on short windows the profile list no longer overflows and clips the lower entries; it now scrolls within the available sidebar space
  • Popped-out serial sessions no longer double your typing — detaching a serial session into its own window now mirrors your echo setting, so each keystroke appears once instead of twice
  • Rock-solid terminal rendering — rolled back an experimental glyph-cache change that could garble or blank text in split panes when switching tabs or sessions; rendering is back to the stable, known-good path
v1.9.2June 14, 2026

License fix & AI hardening

  • Fixed Pro license activation — valid license keys were being wrongly rejected as invalid due to a product-ID mismatch in the activation check. Enter your key again on this version and it activates immediately
  • Safer AI agent commands — the agent now blocks destructive command arguments (like deleting files or flushing routes) before they run, instead of relying on a name-only allowlist
  • Package-install hallucination warning — when an AI suggestion installs a package, NeuroTerm now flags it so you can double-check the name before running it
  • Encrypted credential storage — saved secrets are now encrypted at rest with a machine-derived key, with an atomic, corruption-resistant save path on Linux and Windows
  • Agent plan preview — see the agent’s intended steps before it acts, with a toggle to skip and a quick cancel
  • Clearer AI answer confidence — answers now show a confidence chip based on source count and quality, and low-confidence context is handled more gracefully
  • Reliability fixes — resolved cancel/timeout edge cases in LLM streaming and tightened auto-error handling so rapid re-submits and cancels behave correctly
v1.9.1June 7, 2026

Per-pane input & polish

  • Each split pane now has its own serial input bar — type and send to exactly the session in that pane, with its own connection state, line-ending, and filter, instead of one ambiguous global input that only reached the focused pane
  • Filtered panes stay filtered — a split tab that left and re-entered view no longer briefly dumps the full unfiltered scrollback; each visible pane re-applies its own filter on return
  • Scroll lock now has a StatusBar toggle button — lock the terminal from the status bar in addition to the Scroll Lock key, with a clear active state
  • Spec-audit bug fixes — closing a session no longer leaks its operation context, dev builds can’t poison the “last seen version” banner, ghost-typing now honors your ranking settings, and interrupted SFTP transfers resume from the right path
  • USB serial reconnect wired up — disconnect banner now tracks the device fingerprint so a re-plugged adapter can reconnect
  • Embedding model management — pick, activate, and download embedding models from a dedicated Settings section
v1.9.0May 30, 2026

Split-window panes

  • Split-window panes are now on by default — split any tab side-by-side with Ctrl+Shift+D or stacked with Ctrl+Shift+E, focus panes with Ctrl+Alt+Arrow, resize with Ctrl+Alt+Shift+Arrow, and close with Ctrl+Alt+W
  • Zoom a pane to fill the tab with Ctrl+Shift+Z, then restore it just as fast — great for focusing on one session without losing your layout
  • Broadcast input across panes — Ctrl+Alt+B fans your keystrokes out to every visible pane in a tab (tmux synchronize-panes style), with a first-time warning so you don’t fire a destructive command everywhere by accident
  • Drag a tab onto a pane to split or swap — drop on an edge to split in that direction, drop in the center to swap which session lives there; move sessions across tabs or pop one out into its own tab
  • Layout presets — jump straight to single, vertical split, horizontal split, three-pane, or four-pane grid layouts
  • Smarter SSH host-key handling — a Known Hosts manager with one-click re-trust when a key changes, strict verification with no silent auto-trust
  • Sharper terminal rendering — fixed CJK/multibyte garbling under multi-pane load, eliminated session-switch flicker on long-scroll terminals, and stopped scrollback from being truncated when switching panes
  • Dozens of multi-pane polish fixes — cleaner active-pane outlines, better resize handles, preserved scrollback in narrow panes, and reliable pane close without leaking sessions
v1.8.3May 19, 2026

Tab activity V3 & right-dock polish

  • Tab activity V3 — residual amber pips on Claude Code TUI tabs are gone. A three-layer defense (two-window baseline confirmation, per-row periodic-redraw classifier, layout-resize invalidation) absorbs status-line ticks, post-tab-switch baseline drift, and sidebar/panel reflow while still blinking for real activity
  • Spinner blink preserved — the new classifier explicitly bypasses suppression for fast-cadence single-row changes, so the in-place spinner indicator still works as intended
  • Right-dock resize handle self-heals — dragging the right-docked Panel to a width wider than the current viewport can render no longer leaves the handle floating inside the terminal area; the stored width is clamped to the renderable max on mount and on window resize
  • Viewport-aware drag — keyboard and mouse resize on the right-dock now cap at the actual rendered max instead of the unconditional 600 px ceiling, so drag-delta matches visual-delta from the first pixel
  • Right-docked feedback banner re-centers — the banner now centers over the main column instead of the full viewport when the sidebar or right-dock is expanded
  • Right-dock terminal fits cleanly — xterm characters no longer clip at the right edge during drag-resize; fit() now fires on every width tick (gated to the active session) and coalesces SIGWINCH so non-TUI shell scrollback is protected
  • Right-dock overlays cleared — idle toast, AI toast, update notification, and the @-trigger Magic Input palette now slide clear of a right-docked panel instead of being hidden underneath
v1.8.2May 17, 2026

Pop-out panel & tab activity fixes

  • Detached SessionWindow panel layout fix — in popped-out windows the bottom Panel no longer covers the entire terminal, and the resize-drag handle is reachable again with the separator restored between terminal and panel
  • Tab activity false-positive suppressed — synchronized-output TUIs like Claude Code and OpenCode no longer trip the inactive-tab amber dot on transient mid-parse buffer mutations; the dot now only fires after the parse stream settles
v1.8.1May 16, 2026

Drag-and-drop panel docking

  • Drag-and-drop panel docking — grab the Panel header grip and drop it on the right edge to dock vertically (or back to the bottom). Agent chat state, scroll positions, and in-flight LLM streams all survive the dock change without reload
  • Persistent dock layout — the chosen dock side and width are remembered across restarts, with a single StatusBar toggle that operates on whichever dock is active
  • Polished drop zones — dock-direction icons, single-line labels, wider hit areas, and clearer over-state feedback make the drop target obvious before you release
  • Terminal refit fix — the terminal no longer gets stuck treating a collapsed panel as expanded, eliminating one source of resize-loss when toggling the bottom panel
  • StatusBar Blocks icon cleanup — hides the numeric count next to the icon (still available in the hover tooltip; Alt+5 unchanged)
v1.8.0May 15, 2026

Command Blocks + tab activity v2

  • Command Blocks panel — capture, browse, and replay shell commands in a dedicated panel with one-click navigation back to where they ran in the terminal. Status bar button + Alt+5 hotkey for quick access
  • Boot-stage virtual blocks — pattern markers like "U-Boot Start" or "Systemd Ready" appear in the Blocks panel as virtual rows, even without OSC 133 shell integration
  • Newest-first ordering, inline expand, one-click bookmark — newest commands sit at the top; double-click a row to expand its output inline (height fits content, no fixed cap); single-click any row’s bookmark icon to toggle
  • Context menus everywhere on a block — right-click any colored gutter strip in the terminal or any row in the panel to open the same block actions menu (Copy command, Copy output as Markdown, Send to AI, Rerun, Bookmark, Delete)
  • Absolute timestamps + tighter rows — every block row shows the exact HH:MM:SS it finished (relative "5m ago" available as a hover tooltip), with tighter row height for higher information density
  • Tab activity dot v2 — tabs blink while content streams and use viewport content-hashing to distinguish real output from cursor blinks, so the dot only lights up when something actually changed
  • Memory leak mitigation — long-running sessions hold tighter on memory
v1.7.3April 13, 2026

What’s New polish & marker stability

  • Marker stability — pattern markers now survive terminal resize and TUI redraws instead of disappearing when xterm.js disposes IMarkers
  • What’s New history — re-opening the panel shows the last 5 releases instead of only the current version
  • Version button always clickable — the StatusBar version chip re-opens What’s New after dismiss, with a polished filled-background style
  • What’s New visual polish — improved version glow, section title hierarchy, and list marker styling for better readability
v1.7.2April 12, 2026

Panel resize & TUI stability

  • Panel toggle no longer shrinks terminal rows — fixed multiple resize race conditions that caused line loss when opening or closing the bottom panel
  • TUI app stability — sync-output apps like htop and vim now maintain correct dimensions during panel and sidebar transitions
  • What's New panel — post-update feature discovery via a StatusBar chip and slide-out panel so you never miss new features

  • Structured error annotations — inline error explanations with What/Cause/Fix sections and red line highlighting directly in the terminal
  • Error annotations in Neuro tab — auto-detected errors are saved and browsable in the AI panel with per-session toggle
  • Jinja template fallback — models with unrecognized chat templates now render correctly via Jinja/minja instead of failing
  • Speculative decoding fix — resolved ISWA decode crash affecting Gemma 4 and other interleaved sliding-window models
  • Agent panel polish — fixed hover states, button visibility, idle content wipe, and adaptive CPU timeout for slow prompt processing
  • Key input lag fix — deferred highlighting to RAF flush and optimized ghost typing retries under high throughput
