Release Notes

Core Bugfixes - Gateway Anthropic Opus 4.7+ adaptive reasoning now keeps summarized thinking instead of returning empty thinking blocks. Improvements - Sessions can now store custom metadata through the API and SDK. (@shantur) - Config now loads from the opened location upward, so directory-specific settings and provider policies apply more predictably. TUI Bugfixes - Wrapped inline tool rows now stay aligned, and failed inline tools can expand their error details in place. Thank you to 1 community contributor: - @shantur: - feat(core): add session metadata support (23068)
