Embarcadero announced today that RAD Studio 12.3 Athens, along with Delphi 12.3 and C++Builder 12.3, is available to customers starting today.
You can find a summary of the new features on the Embarcadero site at www.embarcadero.com/products/rad-studio/whats-new-in-12-athens.
You can also read a more detailed set of features on the docwiki at 12_Athens_-_Release_3, along with the list of bugs fixed at New_features_and_customer_reported_issues_fixed_in_RAD_Studio_12.3.
What's the main focus? While there is a lot in this release, the most relevant new feature is the Initial Release of a 64-bit version of the RAD Studio IDE, which means there is a 64-bit Delphi IDE.
While feature limited, this is fantastic milestone for the prodcut! Enjoy!
