letta 0.16.8 released
Lepta 0.16.8 is a small patch release with no new agent-builder features or breaking API changes; the main functional fix is an update to workflows. It also hardens sandbox-to-server tool result transport by switching from pickle to JSON, which is a security improvement rather than a performance change.

letta 0.16.7 released
Letta 0.16.7 raises the default global context window from 32k to 128k and fixes the context window reset bug, with a completely overhauled compaction system that eliminates most manual configuration workarounds for self-hosted users. Block limits are no longer enforced, allowing blocks to grow freely, though users must now manage block size through alternative means if they were previously relying on limits to control per-turn costs.
