I have some good news to report, tempered slightly with a dash of the not so good.
The good first: we’ve just released v13.1.4 of the DevExpress VCL subscription. Among various issue and performance improvements, this release contains full support for Delphi XE5 (both 32- and 64-bit) and C++ Builder XE5 (both 32- and 64-bit), for apps compiled against the VCL run-time.
To learn about the new features and resolved issues in 13.1.4, please visit the What’s New page. If you are still on 12.2 or earlier, here is my blog post about the new features in DevExpress VCL 13.1.
Unfortunately, I must draw your attention to a few known issues with this release that may impact your development. The first two (B232477, B230655) are carried over from previous versions of RAD Studio (XE3, XE4) and are still reported as open in Embarcadero QualityCentral. Since these have been known for a while, I’m guessing that, if you’ve encountered them, you have worked around them to a certain extent.
The third (B238969) is new and appeared in the just-released RAD Studio XE5. In essence, data navigation using the key fields specified via the KeyFieldNames property (Properties.KeyFieldNames in data-aware lookup editors) is broken due to an issue in TClientDataSet. (A similar problem involves numeric filters when used with TClientDataSet.) This functionality is exposed from the XE5 MIDAS.dll, a globally-registered COM component, so not only will it break new or updated applications that use it, but also existing applications (so you might already be aware of the problem). All issues have been reported in QualityCentral and we await their resolution.
