What's New
FalkorDB fixes replication crashes; Scrapling introduces MCP server authentication and persistent browser tabs.
Breaking Changes
- MCP server tools are split into modes (one-shot vs. session-based)
- MCP server HTTP transport now requires authentication by default
- The `get` tool is renamed to `make_request`
New Features
- Persistent browser tabs reuse across requests
- New `Response.markdown()` method for LLM-ready Markdown
- New `SiteToMarkdownSpider` template for crawling entire websites
- MCP server session tools for persistent browser sessions
- MCP server authentication requirements
Improvements
- Performance improvement for graph loading by removing full sync from the decoder
- Replica synchronization stability by fixing SIGSEGV on divergence
- Improved Cloudflare solver (mentioned in summary)
Bug Fixes
- Fix SIGSEGV on replica divergence by triggering full resync instead of crashing
Upgrade Notes
Scrapling users must update MCP server configurations to enable authentication and rename the `get` tool to `make_request`; FalkorDB users can upgrade without configuration changes.
