+## [0.5.0] — 2026-09-18
+
+Point-in-time integrity across every dated path, decisions that are recorded as
+they were made, backtesting over a grid of tickers and dates, the caller's
+portfolio as run input, and SEC EDGAR fundamentals served as filed.
+
+### Highlights
+
+- **Fundamentals as filed.** SEC EDGAR serves US company statements as they stood on the run's date: a period that has ended but has not been filed is not served, and a figure restated later still reads as first reported. Keyless, opt-in via the vendor chain.
+- **Backtesting.** `run_backtest` runs the pipeline over a ticker and date grid into its own decision log, and `summarize` scores the settled cells; `tradingagents backtest` does the same from the CLI.
+- **Portfolio context.** `propagate(..., portfolio=...)` and `--portfolio` let the trader, risk and portfolio agents size against real holdings. A run without one is never treated as a flat book.
+- **Decisions are recorded as made.** An unreadable decision is flagged for review everywhere instead of becoming a tradeable Hold, and a rating argued against is no longer read as the call.
+
+### Point-in-time and honest attribution
+
+- Dated tools take the run's date from graph state, so an omitted or later date cannot reach a vendor. (#1331, #1319, #1118)
+- Insider filings and prediction-market odds are bounded by the run date; insider rows state that a trade becomes public when its Form 4 is filed.
+- A feed that never observed a window reports it as unavailable rather than as an absence, across news, Reddit and StockTwits.
+- The resolved company identity says when it describes today rather than the run date.
+- The verification snapshot quotes the prices the vendor reported, never a gap-filled value.
+- A vendor failure is a vendor failure: yfinance raises instead of returning its errors as text, an outage is not reported as a company with no data, and a chain where every vendor is unavailable says so instead of ending the run.
+- The macro vintage pin is clamped to the vendor's own clock, so a run dated today cannot ask for a vintage it does not have.
+- A historical run is not served a present-day company profile by either fundamentals vendor. (#1300)
+
+### Decisions and evaluation
+
+- The labelled rating decides, whatever separates it, and prose naming several ratings is reviewed rather than guessed.
+- Decision prompts state the shape of their answer, so a provider without structured output still returns a readable decision.
+- A report that was not produced says so, instead of appearing as an empty section.
+- Backtest scoring reads the direction each rating claimed: a Sell that fell is a hit, and Hold reports no hit rate.
+- The outcome window is configurable (`holding_period_days`), and reflection states the window it judges.
+- A settled decision is not logged twice, and a failed reflection no longer stops the next run. (#645)
+- The trader states entry and stop levels as prices, so a percentage no longer fails the whole proposal. (#1288)
+
+### CLI
+
+- `tradingagents backtest`, with `--run-id` to continue an interrupted sweep. (#1234)
+- The previous run's selections come back as prompt defaults. (#1236, #920)
+- A run with no readable rating says so; the live view no longer scrolls; messages that read like Python values are shown. (#649, #784)
+- The state log keeps non-ASCII readable. (#1081)
+
+### Data sources
+
+- SEC EDGAR fundamentals vendor (US filers, keyless).
+- Hong Kong and Shanghai tickers resolve to the symbols Yahoo serves. (#1342, #957, #1260)
+- Reddit is fetched as one combined request per run. (#1286)
+- One OHLCV cache file per symbol. (#1330)
+
+### Models
+
+- Current lineups for every provider: GPT-6 Astra and the GPT-5.6 family, Gemini 3.8 Flash, Claude Opus 5 and Fable 5.1, Grok 4.6, DeepSeek Flash, Qwen 3.8, GLM-5.3, MiniMax M3, Kimi K3 and the current Mistral snapshots.
+- Every provider accepts a model ID the picker does not list.
+- GLM traffic goes to the platform its key belongs to, and Ollama structured output no longer sends a tool_choice it rejects. (#1062)
+
+### Changed
+
+- The memory log records `REVIEW` for a decision with no readable rating, where it previously recorded `Hold`.
+- Optional fields the model did not provide are named as such rather than omitted.
+- Removed dependencies nothing imports: backtrader, redis, setuptools, langchain-experimental, parsel, tqdm. (#1353, #1070)
