Three releases in about eight hours on September 24, 1,060 stars gained today against 17,106 total. The 1.0 release adds a Server SDK and an AI SDK letting agents read and edit documents, update formulas, generate charts and visually inspect the result.

AgentCore Identity added a Consent portal and a session binding endpoint for AgentCore Gateway on September 14, so teams building three-legged OAuth flows no longer host their own session binding infrastructure (AWS). Users authenticate once against a corporate IdP, then grant...
