+## [0.3.0] — 2026-06-22
+
+Stabilization and extensibility release: a CI gate, a unified verified
+data-access contract, a provider and data-vendor registry, and a maintenance
+sweep that hardened config precedence, the model catalog, data resilience, and
+structured output.
+
+### Added
+
+- **CI gate.** GitHub Actions runs the pytest suite across Python 3.10-3.13,
+  strict `ruff`, and a clean-install smoke that imports the package and CLI to
+  catch undeclared dependencies. (#994, #197)
+- **Provider registry.** OpenAI-compatible providers register as a single spec,
+  and a generic `openai_compatible` endpoint covers vLLM, LM Studio, and relays.
+  Adds NVIDIA NIM, Kimi, Groq, Mistral, and a native Amazon Bedrock client.
+- **Macro and prediction-market vendors.** FRED macro indicators and Polymarket
+  event probabilities, surfaced to the news and macro analysts.
+- **Programmatic report output.** `TradingAgentsGraph.save_reports()` writes the
+  same report tree the CLI produces, for headless and API runs. (#1037)
+- **Env-configurable reasoning depth** via `TRADINGAGENTS_OPENAI_REASONING_EFFORT`,
+  `TRADINGAGENTS_GOOGLE_THINKING_LEVEL`, and `TRADINGAGENTS_ANTHROPIC_EFFORT`,
+  each gated to the models that accept it.
+
+### Changed
+
+- **Verified data-access contract.** Symbol normalization on every vendor path
+  (identity, returns, CLI, news); the configured vendor list is the exact
+  resolution chain with no silent fallback to unselected vendors; a typed
+  `VendorError` taxonomy; look-ahead-safe news windows; stale-OHLCV rejection;
+  inclusive yfinance date ranges.
+- **Config precedence.** An explicit `TRADINGAGENTS_*` value or CLI flag now wins
+  over interactive defaults for debate and risk round counts,
+  `--checkpoint / --no-checkpoint`, and the Docker provider profile; invalid
+  boolean env values fail loudly. (#975, #976, #977)
+- **Current-generation model catalog.** Refreshed provider lineups; retired
+  `gpt-4.1`, Claude Sonnet 4.5, and the Gemini 2.5 line.
+- **Optional vendors degrade** instead of aborting a run: a failed macro or
+  prediction-market lookup returns a no-data sentinel.
+- **Analyst prompts lead with the current date** so tool-call date ranges anchor
+  to the run date rather than the model's training cutoff. (#836)
+
+### Fixed
+
+- **Instrument identity.** Deterministic ticker-to-company resolution prevents
+  wrong-company hallucination, and a verified market-data snapshot grounds price
+  and indicator claims. (#814, #830)
+- **Social and market data sources.** Reddit RSS-first with 429 backoff,
+  StockTwits transport hardening, and Alpha Vantage timeout plus
+  key-versus-rate-limit handling.
+- **Structured output.** Local OpenAI-compatible servers no longer reject
+  object-form `tool_choice`; a thinking model that returns no parsed result falls
+  back to free text; null-ish strings in optional price fields coerce to `None`.
+  (#1038, #1051, #1057)
+
+### Removed
+
+- The no-op `analyst_concurrency_limit` config knob; parallel analyst execution
+  is planned for a later release. (#979)
+- The unused committed `uv.lock`. (#1030)
