v0.5.49

v0.5.49 - 2026-10-17

• pi-subagents 0.79.0.
  • Forked research subagents reuse the parent's prompt cache, and /subagent-cost reports no longer ride along in every later request, so parallel runs cost fewer tokens.
  • When a provider stops a subagent with an error such as a content-filter refusal, the error now includes the provider's reply, so a refusal can be told apart from an outage.
  • subagent stays available after an update or /reload mid-session.
• pi-web-access 0.42.0. DeepSeek's Search API is available as a search provider: feynman search set deepseek <key>. It bills each search, so auto never picks it.
• .env.example lists OPENALEX_API_KEY, which raises the OpenAlex rate limit for long literature runs (thanks fanfyh).
