v0.17.0

Added

• Added Gemini API PDF-to-Markdown conversion before local unpdf fallback, with inline PDF upload, page-marker validation, configurable pdf.maxSizeMB, and streamed size enforcement. Thanks José Antonio Galiano Sandoval (@jagaliano) for PR #180.
• Added Searchinfinity (Byteplus Searchinfinity / 豆包搜索 Global edition) as a search provider with searchinfinityApiKey / SEARCHINFINITY_API_KEY credentials, native domain and recency filters, model-generated result summaries, HTTP-semantics mapping for business error codes, provider-array/all-provider routing, and curator selection. Thanks @cyzlmh for PR #186.
• Added Querit as a search and hosted content provider with queritApiKey / QUERIT_API_KEY credentials, native domain and recency filters, optional inline Contents retrieval, provider-array/all-provider routing, curator selection, and a fetch_content fallback. Thanks @MCapricorns for PR #185.

Changed

• The 5MB fetch_content response size limit is now enforced while streaming the decoded body, not just via the Content-Length header. Chunked or compressed pages whose decoded content exceeds 5MB now fail with Response too large (5MB) instead of being buffered unbounded and parsed. Shared config parsing for SSRF and fetch-content domain policy loaders also removes duplicate reads on the fetch hot path.

Fixed

• Fixed filtered zero-config Exa search silently losing its request options: the default keyless MCP tool (web_search_exa) only accepts query and numResults, so type, livecrawl, and contextMaxCharacters were dropped server-side and includeContent never returned page text. Filtered or content-carrying keyless searches now use web_search_advanced_exa — served by the same keyless free tier — which applies includeDomains/excludeDomains, startPublishedDate, highlights, and text limits as real parameters instead of site: / "past week" strings appended to the semantic query. Plain searches stay on web_search_exa, and the advanced path falls back to it if it is unavailable.
• Stopped requesting citation text on keyed Exa /answer calls, which was fetched and then discarded, and stopped requesting page text on keyed /search calls that do not ask for content.
• Exa MCP rate-limit responses (429) now explain that adding exaApiKey to ~/.pi/web-search.json removes the free-tier limit, instead of surfacing a bare status code. Thanks @kesku for PR #187.
