Versioning & Migration#

Breaking changes and deprecations to be aware of when upgrading.

SDK — v0.2.0 API simplification#

The SDK API was simplified in 0.2.0:

• getDocs() was replaced by getContext(query, libraryId, options), which takes a query for relevance-based retrieval
• searchLibrary(query, libraryName) now takes both a query and a library name
• Response types were renamed (Library and Documentation instead of SearchResult, CodeDocsResponse, etc.)
• Pagination, mode, topic, and limit options were removed from context retrieval

CLI — research mode removed (v0.4.1)#

Research mode was removed entirely. The query-docs MCP tool no longer accepts or forwards a researchMode parameter, and the CLI no longer exposes a --research flag on ctx7 docs.

CLI — skill commands deprecated#

The ctx7 skills ... commands are deprecated and will stop working in the next major release. The context7-mcp and find-docs skills installed by ctx7 setup are unaffected.
