In my new role, I am enjoying getting back into a favorite pastime of trawling through the release notes and Metadata API for the latest new features and changes . That’s right – I really do compare the Metadata API as it often uncovers smaller changes or draws attention to something I might have missed in clicking through the documentation. This blog is not exhaustive – it’s simply a quick list of things that caught my eye (thus far) from a more developer, architect, and general architecture perspective . Rest assured, a number of these have gone on the future blogs list for a deeper dive! Integration Features and API Updates External Services continues to impress me with how easy it makes integrating well-documented (aka via OpenAPI schema) external APIs into Apex and Flow. It’s no longer just robotically generating stubs but adding actual platform integration value as well. With async APIs, it does a great job at integrating with platform callbacks.
