v0.3.3

Highlights

• Fix navigation and history races across WebView2 and WebKit, stale frame references, hidden/covered element handling, and MCP logging-order races.
• Improve startup, graphics, and JSON transport overhead; keep hidden macOS automation timers active.
• Add a shared browser Test Lab with 305 fixtures, native JSONL/MCP coverage, cross-platform CI, and a published interactive catalog.
• Add tested Linux AMD64/ARM64 Docker images and Docker Hub publishing.
• Add reproducible launch assets, native MCP packaging, and expanded website documentation.

Downloads

Native archives cover macOS ARM64/x86_64, Linux ARM64/x86_64, and Windows x86_64. Verify them with SHA256SUMS.

The cross-platform native MCP bundle, bruster-0.3.3.mcpb, includes all five verified executables. Its checksum and package metadata are in MCP-SHA256SUMS and server.json.

The bundle launcher was exercised through MCP in CI; bruster-mcp-demo.mp4 was captured from this release.

Linux native builds require WebKitGTK 4.1 and a display or Xvfb; Windows requires WebView2. The Docker image includes its Linux browser runtime.

v0.3.2

Highlights

• Fix hidden and MCP startup on Linux when desktop portals are unavailable or stalled.
• Make page-request deadlines reliable across navigation, cancellation, and redispatch; improve MCP shutdown and profile persistence.
• Fix macOS navigation races, native load-failure recovery, and cancellation of superseded requests.
• Fix screenshot viewport restoration and Windows history synchronization, with required native Windows smoke, edge, and public-site tests.
• Improve Wikipedia search and history coverage, including responsive controls and bounded recovery from Wikimedia rate limits.
• Add reproducible browser benchmarks and published performance reports.

Downloads

Prebuilt archives are provided for macOS (Apple Silicon and Intel), Linux (ARM64 and x86_64), and Windows (x86_64). SHA256SUMS contains checksums for all five archives.

Linux requires WebKitGTK 4.1 and Xvfb when running without a desktop display. Windows requires the WebView2 runtime.
