7.21.0

Minor changes

• 888a725 Add posthog.mcp, a Python SDK for PostHog MCP analytics (just pip install posthog; the MCP SDK is a peer dependency of instrument(), not bundled). instrument(server, posthog_client) wraps a FastMCP or low-level mcp.server.Server so every tool call, agent intent, tools/list, initialize, and failure is captured to PostHog as a $mcp_* event. Also adds PostHogMCP, a Client subclass for custom dispatchers (needs nothing beyond posthog), plus opt-in context intent capture, identify, report_missing (get_more_tools), and conversation_id. Beta. — Thanks @lucasheriques for your first contribution 🎉!

7.20.5

Patch changes

• cdd878c Clear feature flag called cache on shutdown — Thanks @marandaneto!

7.20.4

Patch changes

• 89adb2f Fix internal imports for posthoganalytics mirror — Thanks @hpouillot!

7.20.3

Patch changes

• 42ff4ca Detect and redact high-entropy secrets (API keys, tokens, passwords) in exception code variables. Adds the code_variables_detect_secrets option (default True). — Thanks @ablaszkiewicz!

7.20.2

Patch changes

• c359f93 Mask sensitive data held inside objects and in URL/DSN credentials when capturing exception code variables. Custom objects are now traversed so fields like password are redacted by attribute name instead of leaking via repr(), and credentials embedded in connection strings are scrubbed. Adds the code_variables_mask_url_credentials option (default True). — Thanks @ablaszkiewicz!
• c359f93 Improve strict Pyright coverage for public PostHog APIs. — Thanks @ablaszkiewicz!

7.20.1

Patch changes

• 09c8fba Warn on duplicate async PostHog clients and document client lifecycle guidance — Thanks @marandaneto!

7.20.0

Minor changes

• bc8e531 Add a default timeout for flushing queued events. — Thanks @marandaneto!

7.19.2

Patch changes

• 98a305a Increase the default background flush interval to 5 seconds — Thanks @marandaneto!

7.19.1

Patch changes

• 8d416ae Add missing return type annotations to improve typing coverage without changing runtime behavior. — Thanks @miachillgood for your first contribution 🎉!

7.19.0

Minor changes

• b9f3208 Add opt-in client-side rate limiting for exception autocapture, using the same token bucket algorithm as the posthog-js and posthog-node SDKs: a bucket per exception type allows a burst of captures, then refills over time. Rate-limited exceptions are skipped before they reach the ingestion queue. Disabled by default; enable with the new enable_exception_autocapture_rate_limiting client option and tune via exception_autocapture_bucket_size (default 50), exception_autocapture_refill_rate (default 10), and exception_autocapture_refill_interval_seconds (default 10). — Thanks @hpouillot!
