Headline themes in v0.2.5:
- Sentiment Analyst grounded in real data. Renamed from social_media_analyst
and redesigned to pre-fetch Yahoo News, StockTwits, and Reddit before the
LLM is invoked, ending the prior fabrication behavior.
- MiniMax provider with full M2.x catalog and dual-region split. Qwen and
GLM also split into international + China regions with separate API keys
and a clean secondary region prompt in the CLI.
- TRADINGAGENTS_* env-var overlay for DEFAULT_CONFIG with type-aware
coercion; .env loading centralized so every entry point sees the user's
keys. Interactive API-key detection prompts and persists missing keys
to .env on the fly.
- OLLAMA_BASE_URL end-to-end for remote ollama-serve, plus a Custom model
ID option in the Ollama dropdown.
- Configurable news-fetch parameters and configurable alpha benchmark for
non-US tickers (.NS / .T / .HK / .L / .TO / .AX / .BO ship with sensible
regional defaults).
- Multi-language output now propagates to every user-facing agent
(researchers, risk debators, research manager, trader) instead of only
the analysts and portfolio manager.
- Model catalog refresh across all providers (GPT-5.5 frontier, Claude
Opus 4.7, Gemini 3.1 Flash-Lite GA, Grok 4.20, Qwen 3.6 line).
- Capability-dispatch table drives provider-specific structured-output
quirks (DeepSeek V4/reasoner and MiniMax M2.x tool_choice rejection,
MiniMax reasoning_split) so the general client stays clean.
- Fixes: ticker path-traversal validation (security), dotenv loading via
console script, reports save bug, exchange-suffix truncation in the
ticker prompt, Docker permission errors, deepcopy config isolation,
max_recur_limit plumbing, clearer missing-API-key error.

This release bundles substantial work since v0.2.3:
- Structured-output Research Manager, Trader, and Portfolio Manager
(canonical with_structured_output pattern, single LLM call per agent,
rendered markdown preserves the existing report shape).
- LangGraph checkpoint resume for crash recovery (--checkpoint flag).
- Persistent decision log replacing the per-agent BM25 memory, with
deferred reflection driven by yfinance returns + alpha vs SPY.
- DeepSeek, Qwen, GLM, and Azure OpenAI provider support; dynamic
OpenRouter model selection.
- Docker support; cache and logs moved to ~/.tradingagents/ to fix
Docker permission issues.
- Windows UTF-8 encoding fix on every file I/O site.
- 5-tier rating consistency (Buy / Overweight / Hold / Underweight / Sell)
across Research Manager, Portfolio Manager, signal processor, memory log.
Plus the small quality items in this commit:
1. Suppress noisy Pydantic serializer warnings from OpenAI Responses-API
parse path by defaulting structured-output to method="function_calling"
(root-cause fix, not a warnings filter — same typed result, no warnings).
2. Ship scripts/smoke_structured_output.py so contributors can verify
their provider's structured-output path with one command.
3. Add opt-in memory_log_max_entries config — when set, oldest resolved
memory log entries are pruned once the cap is exceeded; pending
entries (unresolved) are never pruned.
4. backend_url default changed from the OpenAI URL to None so the
per-provider client falls back to its native endpoint instead of
leaking OpenAI's URL into Gemini / other clients.
CHANGELOG.md added with the full v0.2.4 entry. 92 tests pass without API keys.
