# Changelog

## Unreleased

- Add opt-in Anthropic context compaction via `contextOptions.compaction`
(`triggerTokens` / `instructions`); summarizes earlier context server-side and
replays the summary on later turns. Widens the recent-message window for
Anthropic runs so history can reach the trigger. (#287)
- Bump `@ai-sdk/anthropic` to 3.0.62 (adds `compact_20260112`) and `ai` to
6.0.209, with matching `@ai-sdk/provider-utils` 4.0.30 / `@ai-sdk/provider`
3.0.10.

## 0.6.4

- Fix streaming UI message dedupe (#281)
