RAD Studio 10.4 Sydney - Release 2 (also known as 10.4.2) is available for installation. 10.4.2 builds on the feature set of 10.4 and 10.4.1, enhancing existing features throughout the product, and adding new capabilities. Delphi 10.4.2, C++Builder 10.4.2, and RAD Studio 10.4.2 are available to download to any active Update Subscription customer. RAD Studio 10.4.2 includes additional features (as detailed below) as well as a significant focus on quality improvements. RAD Studio 10.4.2 includes all patch fixes from 10.4.1

Embarcadero has just released two patches for RAD Studio, Delphi, and C++Builder 10.4.2. The patches address a few critical issues in the most recent releases and are available to active update subscription customers in the GetIt Package manager. A matching alert shows up in the IDE Welcome page.

The patches are delivered as deferred installation packages, which means they are installed after you shut down the IDE. This means you can activate both GetIt packages, without restarting the IDE after the first one, and than close the IDE and install both of them in a single cycle. Remember you’ll also need to accept the UAC Windows prompt. Details of the two patches, extracted from their readme files, are below.

Update (May 3rd): There is now an additional, third patch also on GetIt as it turned out we missed a few files from the General patch to address a critical exceptions handling issues on non-Windows platforms (RSP-33117).
