- The HTTP client has been migrated from an axios-based library to native
fetchAPI throughout the transport layer. This is an internal change but may affect proxy configurations that relied on axios-specific behavior. - The download URL for Claude Code releases changed from a Google Cloud Storage URL to
https://downloads.claude.ai/claude-code-releases. - Connection adapters (Direct Connect, SSH) were refactored from a class-based to a factory pattern. The internal hook names changed from
useDirectConnect/useSSHSessionto factory labelsdirectConnect/ssh. - The
length limitssystem prompt instruction ("keep text between tool calls to ≤25 words") was removed, giving the model more flexibility in response length. - Organizations using AWS credential configuration through the settings UI should migrate to either API key authentication or the new OIDC Federation system.
