## Releases

### v0.3.1 — TradingAgents v0.3.1

- Date: 2026-07-05
- Version: v0.3.1
- Original notes: https://github.com/TauricResearch/TradingAgents/releases/tag/v0.3.1
- Permalink: https://whatsnew.fyi/product/tradingagents/releases/v0.3.1

- **fixed** — Alpha Vantage look-ahead filter now runs because the fundamentals payload is JSON-serialized and the dict-only guard was skipped, allowing future-dated reports to leak into historical runs
- **fixed** — News analyst prompt now matches the tool by accepting a ticker instead of advertising a free-text query parameter
- **fixed** — Shared debate and risk routers no longer crash mid-run by providing every edge with the complete path map instead of returning more targets than mapped
- **fixed** — Checkpoint resume now respects graph shape by folding thread id with selected analysts, debate/risk depth, and asset mode
- **fixed** — Crypto sentiment sources now resolve by mapping crypto symbols correctly for StockTwits and Reddit using their respective formats
- **added** — Configurable LLM retry budget via llm_max_retries parameter and TRADINGAGENTS_LLM_MAX_RETRIES environment variable forwarded to every provider
- **added** — Bedrock API-key authentication via AWS_BEARER_TOKEN_BEDROCK that takes precedence over ambient AWS_PROFILE
- **added** — Latest Claude models including Claude Sonnet 5 (claude-sonnet-5) and Claude Fable 5 (claude-fable-5) with effort control coverage for the Claude 5 line

##### Summary

TradingAgents v0.3.1 is a correctness and stability patch on top of v0.3.0.

##### Fixed

- **Alpha Vantage look-ahead filter now runs.** The fundamentals payload is a JSON string, so the dict-only guard silently skipped filtering and future-dated reports leaked into historical runs. (#1115, @zachthebird)
- **News analyst prompt matches the tool.** It advertised `get_news(query, ...)` while the tool takes a ticker, so the model hallucinated free-text query calls. (#1116, @shcheuk)
- **Shared debate/risk routers can't crash mid-run.** Both routers returned more targets than any one edge mapped; every edge now shares the complete path map. (#1088, @Fr3ya, @sa7an7, @Sushanth012)
- **Checkpoint resume respects graph shape.** The thread id folds in selected analysts, debate/risk depth, and asset mode, so a resume under different choices no longer continues the wrong graph. (#1089, @bossjoker1, @Ghraven)
- **Crypto sentiment sources resolve.** StockTwits lists crypto as `<BASE>.X` (Yahoo's `BTC-USD` 404s) and Reddit needs the base symbol; the social path now maps crypto for both. (#1113, @suremadoreai)

##### Added

- **Configurable LLM retry budget.** `llm_max_retries` / `TRADINGAGENTS_LLM_MAX_RETRIES`, forwarded to every provider so a transient 429 burst doesn't abort a run. (#1091, @yanggaome)
- **Bedrock API-key auth.** `AWS_BEARER_TOKEN_BEDROCK` authenticates Amazon Bedrock without AWS access keys and takes precedence over an ambient `AWS_PROFILE`. (#1103, @praxstack)
- **Latest Claude models.** Added Claude Sonnet 5 (`claude-sonnet-5`) and Fable 5 (`claude-fable-5`); effort control now covers the Claude 5 line.

##### Summary

TradingAgents v0.3.0 is a stabilization and extensibility release: a verified data-access contract, an expanded provider and data-vendor registry, a current-generation model catalog, and a CI gate.

##### Verified Data-Access Contract

Symbol normalization now runs on every vendor path (identity, returns, CLI, news). The configured vendor list is the exact resolution chain (no silent fallback to unselected vendors), and failures surface through a typed `VendorError` taxonomy. News windows are look-ahead-safe, stale OHLCV is rejected instead of reported as current, and yfinance fetches include the requested end date. A verified market-data snapshot grounds price and indicator claims, and deterministic ticker-to-company resolution stops the wrong-company hallucination.

##### Provider Registry

OpenAI-compatible providers register behind a single spec, and a generic `openai_compatible` endpoint covers vLLM, LM Studio, and relays. Adds NVIDIA NIM, Kimi (Moonshot), Groq, and Mistral, plus a native Amazon Bedrock client.

##### Data Vendors

FRED macro indicators and Polymarket event probabilities are surfaced to the news and macro analysts. Optional vendors degrade to a no-data sentinel instead of aborting a run.

##### Model Catalog

Refreshed to current-generation lineups across providers; retired `gpt-4.1`, Claude Sonnet 4.5, and the Gemini 2.5 line. Reasoning depth is configurable via `TRADINGAGENTS_OPENAI_REASONING_EFFORT`, `TRADINGAGENTS_GOOGLE_THINKING_LEVEL`, and `TRADINGAGENTS_ANTHROPIC_EFFORT`, each gated to the models that accept it.

##### Configuration and CLI

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. Analyst prompts lead with the current date so tool-call date ranges anchor to the run date.

##### Tooling

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. `TradingAgentsGraph.save_reports()` writes the same report tree the CLI produces, for headless and API runs.

- Date: 2026-05-11
- Version: v0.2.5
- Original notes: https://github.com/TauricResearch/TradingAgents/releases/tag/v0.2.5
- Permalink: https://whatsnew.fyi/product/tradingagents/releases/v0.2.5

- **changed** — Sentiment Analyst now reads real Yahoo News, StockTwits, and Reddit data before generating its report instead of potentially fabricating social posts
- **added** — MiniMax provider support with full M2.x catalog (204K context) and dual-region configuration via MINIMAX_API_KEY and MINIMAX_CN_API_KEY
- **added** — Dual-region Qwen and GLM support with separate keys per region (DASHSCOPE_* and ZHIPU_*) selectable via secondary region prompt

- **added** — API key auto-detection and persistence to .env when a selected provider's key is missing, allowing CLI to continue without restart
- **added** — Remote Ollama support via OLLAMA_BASE_URL for both CLI and programmatic usage with resolved endpoint display and malformed input warnings
- **added** — Custom model ID option for Ollama to select any pulled model
- **changed** — Alpha computation now uses regional benchmarks for non-US tickers (.NS for ^NSEI, .T for ^N225, .HK for ^HSI, .L for ^FTSE, .TO for ^GSPTSE, .AX for ^AXJO, .BO for ^BSESN) to eliminate FX drift in alpha figures
- **added** — News-fetch parameters (per-ticker article limit, macro headline limit, lookback window, macro search queries) now exposed via DEFAULT_CONFIG for strategy-specific tuning
- **changed** — output_language setting now propagates to all user-facing agents including researchers, risk debators, research manager, and trader for complete localization
- **security** — Add ticker path-traversal validation at every filesystem-path site
- **fixed** — pip install . installations now pick up the project .env when running the CLI as a console script
- **fixed** — Reports save end-to-end with streamed chunks no longer dropped from complete_report.md
- **fixed** — Ticker prompt now preserves exchange suffixes (.SH, .SZ, .SS, .HK, .T, etc.)
- **fixed** — Docker permission errors no longer block first-run write to ~/.tradingagents/
- **fixed** — Config state no longer leaks between runs when sub-dicts are mutated
- **fixed** — max_recur_limit config now applies to the propagator
- **fixed** — Missing-API-key error now names the exact environment variable to set

##### Summary

TradingAgents v0.2.5 ships the grounded Sentiment Analyst, Qwen/GLM/MiniMax dual-region support, \`TRADINGAGENTS_*\` env-var configurability with API-key auto-detection, remote Ollama support, configurable alpha benchmarks for non-US tickers, and a ticker path-traversal fix.

##### Sentiment Analyst

The renamed Sentiment Analyst now reads real Yahoo News, StockTwits, and Reddit data before generating its report, replacing the prior flow that could fabricate social posts under prompt pressure. The new name flows through the CLI dropdown, status panel, and final reports; \`AnalystType.SOCIAL = \"social\"\` is kept for saved-config back-compat.

##### Provider Coverage

- **MiniMax** with the full M2.x catalog (204K context), plus dual-region Global (\`MINIMAX_API_KEY\`) and China (\`MINIMAX_CN_API_KEY\`).
- **Dual-region Qwen and GLM** with separate keys per region (\`DASHSCOPE_*\`, \`ZHIPU_*\`), chosen via a secondary region prompt so the main provider dropdown stays clean.
- **Catalog refresh** across every provider: GPT-5.5 frontier, Claude Opus 4.7, Gemini 3.1 Flash-Lite GA, Grok 4.20, Qwen 3.6 line. Versioned IDs only; auto-shifting aliases moved to a \"Custom model ID\" option.
- **Structured output now works on DeepSeek V4 / reasoner and MiniMax M2.x** — those providers reject \`tool_choice\`; the binding flow now skips it automatically.

##### Configuration via Environment

\`TRADINGAGENTS_*\` env vars override \`DEFAULT_CONFIG\` keys with type-aware coercion (string / int / bool) — \`llm_provider\`, deep/quick model IDs, \`backend_url\`, \`output_language\`, debate-round counts, the checkpoint flag, and the benchmark ticker. When a selected provider's API key is missing, the CLI prompts for it and persists the value to \`.env\` so the run continues without restart.

##### Ollama

\`OLLAMA_BASE_URL\` makes remote \`ollama-serve\` first-class for both the CLI and programmatic users. The CLI prints the resolved endpoint after selecting Ollama and warns on common malformed inputs. A new \"Custom model ID\" option lets users pick any model they have pulled via \`ollama pull\`.

##### Reflection

Alpha is now computed against a regional benchmark for non-US tickers — \`.NS\` (^NSEI), \`.T\` (^N225), \`.HK\` (^HSI), \`.L\` (^FTSE), \`.TO\` (^GSPTSE), \`.AX\` (^AXJO), \`.BO\` (^BSESN), SPY for US listings. Eliminates FX drift dominating the alpha figure for non-USD listings. \`benchmark_ticker\` overrides the suffix map when set explicitly.

News-fetch parameters (per-ticker article limit, macro headline limit, lookback window, macro search queries) are now exposed via \`DEFAULT_CONFIG\` for strategy-specific tuning.

##### Multi-language

\`output_language\` now propagates to every user-facing agent — researchers, risk debators, research manager, and trader — ending the previous partial-localization reports where only analysts and the portfolio manager respected the setting.

##### Fixes

- **Security**: ticker path-traversal validation at every filesystem-path site.
- **\`pip install .\` installations now pick up the project \`.env\`** when running the CLI as a console script.
- **Reports save end-to-end** — streamed chunks were previously dropped from \`complete_report.md\`.
- **Ticker prompt preserves exchange suffixes** (\`.SH\`, \`.SZ\`, \`.SS\`, \`.HK\`, \`.T\`, etc.).
- **Docker permission errors** no longer block first-run write to \`~/.tradingagents/\`.
- **Config state no longer leaks between runs** when sub-dicts are mutated.
- **\`max_recur_limit\` config actually applies** to the propagator.
- **Missing-API-key error** names the exact env var to set.
- **Quieter startup** — suppressed the noisy upstream langgraph-checkpoint deprecation warning.

### v0.2.4 — TradingAgents v0.2.4

- Date: 2026-04-25
- Version: v0.2.4
- Original notes: https://github.com/TauricResearch/TradingAgents/releases/tag/v0.2.4
- Permalink: https://whatsnew.fyi/product/tradingagents/releases/v0.2.4

- **added** — Structured-output decision agents using llm.with_structured_output(Schema) for Research Manager, Trader, and Portfolio Manager that return typed Pydantic instances
- **added** — Automatic selection of each provider's native structured-output mode (json_schema for OpenAI/xAI, response_schema for Gemini, tool-use for Anthropic, function-calling for OpenAI-compatible providers)
- **added** — Opt-in checkpoint resume via --checkpoint flag with per-ticker SQLite databases under ~/.tradingagents/cache/checkpoints/
- **added** — Persistent decision log that stores decisions automatically and resolves prior pending entries with realised return, alpha vs SPY, and reflection on next same-ticker run
- **added** — DeepSeek, Qwen (Alibaba DashScope), GLM (Zhipu), and Azure OpenAI providers
- **added** — Dynamic OpenRouter model selection
- **added** — Docker support with multi-stage build for cross-platform deployment
- **changed** — Five-tier rating scale (Buy / Overweight / Hold / Underweight / Sell) used consistently across Research Manager, Portfolio Manager, signal processor, and memory log
- **changed** — Default backend_url is now None so each provider client falls back to its native endpoint instead of using OpenAI URL
- **changed** — Cache and log directories moved to ~/.tradingagents/ to resolve Docker permission issues
- **changed** — SignalProcessor reads rating from rendered Portfolio Manager markdown via deterministic heuristic instead of extra LLM call per analysis
- **changed** — OpenAI structured-output calls default to method="function_calling" to avoid noisy Pydantic serialization warnings
- **fixed** — Empty memory no longer triggers fabricated past-lessons due to redesigned memory layer
- **fixed** — Windows users no longer hit UnicodeEncodeError by making all file I/O pass explicit encoding="utf-8"
- **fixed** — Tool-call logging processes every chunk message and memory score normalization handles empty arrays
- **removed** — Per-agent BM25 memory replaced by persistent decision log

##### Summary

TradingAgents v0.2.4 ships structured-output decision agents, opt-in checkpoint resume, a persistent decision log with outcome-grounded reflections, four new LLM providers, and a Docker image.

##### Structured-Output Decision Agents

- Research Manager, Trader, and Portfolio Manager use `llm.with_structured_output(Schema)` on their primary call and return typed Pydantic instances.
- Each provider's native structured-output mode is selected automatically (json_schema for OpenAI / xAI, response_schema for Gemini, tool-use for Anthropic, function-calling for OpenAI-compatible providers).
- Render helpers preserve the existing markdown shape, so memory log, CLI display, and saved reports keep working unchanged.
- Five-tier rating scale (Buy / Overweight / Hold / Underweight / Sell) used consistently across Research Manager, Portfolio Manager, signal processor, and the memory log.

##### Persistence & Recovery

- LangGraph checkpoint resume via `--checkpoint`. State is saved after each node so crashed or interrupted runs resume from the last successful step. Per-ticker SQLite databases under `~/.tradingagents/cache/checkpoints/`.
- Persistent decision log replaces the per-agent BM25 memory. Decisions are stored automatically at the end of every analysis; the next same-ticker run resolves prior pending entries with realised return, alpha vs SPY, and a one-paragraph reflection.
- Optional `memory_log_max_entries` config caps resolved entries; pending entries are never pruned.

##### Provider Coverage

- DeepSeek, Qwen (Alibaba DashScope), GLM (Zhipu), and Azure OpenAI providers added.
- Dynamic OpenRouter model selection.
- Default `backend_url` is now `None` so each provider client falls back to its native endpoint instead of leaking the OpenAI URL into Gemini and other clients.

##### Cross-Platform & Deployment

- Docker support with multi-stage build for cross-platform deployment.
- Cache and log directories moved to `~/.tradingagents/` to resolve Docker permission issues.
- All file I/O passes explicit `encoding="utf-8"`, so Windows users no longer hit `UnicodeEncodeError`.

##### Stability

- Empty memory no longer triggers fabricated past-lessons; the redesigned memory layer makes this structurally impossible.
- `SignalProcessor` reads the rating from the rendered Portfolio Manager markdown via a deterministic heuristic, eliminating an extra LLM call per analysis.
- OpenAI structured-output calls default to `method="function_calling"` to avoid noisy Pydantic serialization warnings from langchain-openai's Responses-API parse path.
- Tool-call logging processes every chunk message; memory score normalization handles empty arrays.
- Pytest fixtures (lazy LLM client imports plus placeholder API keys) so the test suite runs cleanly without credentials.
