## Legacy Intelligence Features Deprecated

We have deprecated several legacy Intelligence feature parameters. As of today, requests using these legacy parameters will return HTTP 400 errors. Please update your implementation to use the current parameters.

### What's Changed

#### Sentiment Analysis
- **Legacy**: `analyze_sentiment=true`
- **Current**: `sentiment=true`
- **Action Required**: Update your API requests to use `sentiment=true`

#### Topic Detection
- **Legacy**: `detect_topics=true`
- **Current**: `topics=true`
- **Action Required**: Update your API requests to use `topics=true`

#### Summarization
- **Legacy**: `summarize=v1` and V1 response structure
- **Current**: `summarize=true` or `summarize=v2` (both return V2 structure)
- **Action Required**:
  - Remove any usage of `summarize=v1`
  - Update response parsing for `summarize=true` to use V2 structure
  - V2 returns a single `summary` object across all channels with `result` and `short` properties
  - V1 returned a `summaries` array with `summary`, `start_word`, and `end_word` per channel
