What's New in LastBrowser?

All updates, performance improvements, new features, and the upcoming development roadmap at a glance.

v0.1.59

Published October 22, 2026. The installer is now significantly smaller (~300 MB instead of ~610 MB) as model files are no longer bundled. Setup and Portable are signed with a Certum certificate; checksums see download page (SHA-256).

GitHub · v0.1.59
v0.1.58

Published October 17, 2026. Beta update subscription with a notice about unsigned daily builds; release pipeline for the daily beta and stable channels; desktop build fix with pinned Python runtime dependencies for Sidekick. Setup and Portable are Authenticode-signed (Certum); checksums see SHA256SUMS.

GitHub · v0.1.58
v0.1.55

Published October 12, 2026. Standardchat supports Stop during startup; Quickchat shows Stop during model discovery. Model catalogs are reused per profile and configuration. Known limitations: first startup may show a black area until Ctrl+R; signed-package VM acceptance remains open. Improved chat latency is not confirmed.

GitHub · v0.1.55
v0.1.53 · publishedOctober 11, 2026

Version 0.1.53 was published on October 11, 2026. It fixes blocked navigation during first-run setup. Setup and Portable are signed; their SHA-256 checksums on the download page match the published GitHub assets.

v0.1.52 · published
October 10, 2026

Release 0.1.52 consolidates hotfixes for tab pinning, profile menu interactions, session identity preservation during OAuth, and Windows long-path hardware scans.

  • Tab Pinning & Profile Menu: Reliable drag-and-drop for pinned tabs and responsive pointer interaction across compact and split viewports.
  • Session identity & OAuth: Full preservation of browser user identity during Google and third-party OAuth flows without session resets.
  • Smart Track Spaces: Resilient Space setup and error-free hardware scanning across deep Windows directory trees and long paths.
  • Model Resolution & Stability: Guaranteed safe default model resolution for new profiles, hardened worker lifecycle, and Authenticode + Widevine VMP signing.
v0.1.47 · TEST prereleaseOctober 7, 2026

These items describe focused source corrections in this separate test version. The signed test package is available; practical runtime and provider acceptance remain open. Test release on GitHub.

  • Providers and model catalog: Requests are bound to the saved Space/profile context and payloads receive strict validation. Additional bridge diagnostics help locate early chat-start failures; they do not confirm the cause of the earlier guest timeout.
  • Quick Chat: Transcript and status remain associated with their original context after a Space switch. Reset is complete only after a positive acknowledgment; stale or unavailable model selections are blocked.
  • MiMo settings: Provider-specific labeling and confirmation-based key status prevent an unverified state from appearing as a saved connection. Successful inference has not been demonstrated.
  • Other UI changes: Update notice and “Update now”, post-update notice, log alias, and hiding the ineffective Trust switch are included in the test package; visible runtime behavior has not been accepted.

This is a test prerelease, not a stable version. The v0.1.52 stable-download and update targets remain unchanged. VM, provider, and two-profile acceptance remain open; not Store-certified.

v0.1.45 · publishedOctober 5, 2026

Version 0.1.45 was released on October 5, 2026. It brings the compact composer with AUTO and “More”, compact goal controls, a closer link between Space Assistant and Quick Chat, and a simpler local setup flow.

  • AUTO: An eligible configured orchestrator is preferred. Otherwise, AUTO uses fresh observed limit headroom only when known for every candidate, then compares active/recent local requests and uses configured order to break ties. It does not optimize semantic quality or cost. The 350M router failed its independent quality holdout; Teamwork remains a separate explicit choice.
  • Local AI: PC checks and setup guidance exist in source; production inference, runtime/license evidence, and package acceptance remain open. The RAM guard has not been qualified across supported hardware.
  • Teamwork: The three-step loopback test passed on a controlled local path. It does not establish paid-model or external-provider quality.
  • Signed setup and portable downloads, with their checksums, are available on the download page.
v0.1.44 · publishedOctober 3, 2026

v0.1.44 was published on October 3, 2026 from an earlier source revision. This website does not list newly verified filenames or checksums for that release.

v0.1.43 Previous release
October 2, 2026

Alibaba Cloud restores the saved workspace and discovers text models. Model selection keeps the chosen provider explicit; setup and portable are signed.

v0.1.42 Previous release
October 1, 2026

Persistent goals retain earlier steps. Ollama Cloud, Teamwork, and streaming were checked in the packaged app.

v0.1.41 Previous release
October 1, 2026

Stability and reliability update with corrected Teamwork model selection and clearer authentication status.

  • Windows setup and portable downloads are available on the download page.
  • Release notes and files on GitHub. GitHub.
v0.1.38 Previous release
September 29, 2026

Stability and provider fixes since v0.1.34. This previous Windows release remains available on GitHub.

  • Windows setup and portable builds are available on the download page.
  • Release notes and assets are listed on GitHub.
v0.1.33
September 25, 2026

Feature & Stability Update: Teamwork and Smart Track configuration, Zen Hover Reveal, Space Setup Assistant, and Dock Fisheye Animation.

  • Teamwork & Smart Track Orchestrator: Multi-model collaborative agent team (Lead, Researcher, Analyst, Critic) and single-lane token-efficient Smart Track mode with adaptive effort tiers (Low, Medium, High).
  • Focus Mode Hover Reveal: 8px left edge hover zone smoothly slides the sidebar into view as a floating overlay without displacing web page layout.
  • Dock Fisheye & Hover Titles: Fluid macOS-inspired dock fisheye effect with dynamic scaling and progressive dimming of adjacent icons in slim dock mode.
  • Space Setup Assistant: 3-step creation wizard for new spaces with presets (Coding, Research, Media, Blank), accent colors, and custom AI model routing.
  • Downloads Overlay & Floating Dock: Detachable downloads panel with persistent screen positioning, pill minimization, and multiple docking slots.
  • Instant Live Auto-Save: Theme, font size, page zoom, and notification preferences now persist instantly with zero delay without a separate save button.
v0.1.32 September 25, 2026

Major Milestone: Space Session Isolation, Space Hub Start Page, and Castlabs Widevine integration.

  • Space Session Isolation: Spaces use separate persistent partitions (persist:profile:space) for browser session data.
  • Space Hub Dashboard: New Space section on the start page displaying active Spaces, live tab counters, quick switching, and an inline "+ New Space" creation modal.
  • Castlabs Widevine DRM: Integration of the Castlabs Electron build for Widevine-protected media. Playback still depends on the requirements of each streaming service.
  • Split-View Rendering Fixes: Smooth tab switching between dual-tab split-view and standard tabs without stuck rendering states.
v0.1.31 September 24, 2026
  • Unified Extension & Skill Hub: Chrome MV3 WebExtensions and external MCP servers united under a single hotkey (Ctrl+Shift+X).
  • Modern Popart Icons: High-resolution 32px & 64px vector icons across the sidebar navigation.
  • Grounding Anchors: In-page text highlights when Sidekick performs cross-tab synthesis.
v0.1.30 September 22, 2026
  • AI provider integrations: Connect configurable providers for Sidekick.
  • ConPTY PowerShell Terminal: Full Windows PowerShell terminal inside the browser sidebar with interactive agent TUI and doctor self-repair command.
  • Smart Tab Discarding: Automated tab hibernation to dramatically reduce RAM and power usage.
