Changelog & Roadmap – Lastbrowser

v0.1.32 Current Beta Release

September 25, 2026

Major Milestone: 100% Space Session Isolation, Space Hub Start Page, Castlabs Widevine VMP Signing & EV Authenticode.

100% Space Session Isolation: Each Space now maintains an independent partition key (persist:profile:space). Logins for Google, Disney+, or GitHub are strictly isolated between Spaces with zero session spillover.
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: Complete integration with Castlabs Electron and Video Multi-Part Protection (VMP) code signing. Netflix, Disney+, Spotify, and Prime Video stream reliably with full hardware acceleration.
Split-View Rendering Fixes: Smooth tab switching between dual-tab split-view and standard tabs without stuck rendering states.
Extended Validation (EV) Code Signing: All release binaries (NSIS Setup & Portable) are officially signed and timestamped under Dominik Rainer (Certum CA).
Complete Test Verification: 71 Vitest suites with 625 tests passing; 27/27 Microsoft Store preflight checks green.

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 Nova AI performs cross-tab synthesis.

v0.1.30 September 22, 2026

Multi-Account Gemini CLI: Cyclic load balancing and automatic failover on quota limits (HTTP 429) with real-time status badges.
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.
