Blogs Embarcadero Rad Studio XE4 supported TatukGIS Developer Kernel 10 for VCL now supports the newly released Embarcadero RAD Studio XE4. At the moment, the DK-VCL edition supports the following versions: XE4 XE3 XE2 XE 2010 2009 2007 We will discontinue RAD Studio 2007 support very soon. From that time, we will maintain only Unicode versions. So, if you are still using Delphi/C++Builder version 2007, it is definitely now time to consider upgrading to a newer version. Generally the TatukGIS practice is to support the 5 most recent versions of the Embarcadero development platform. It was easier to keep this scheme as long as Embarcadero released a product upgrade once a year. Release XE4 a bit breaks this tradition. You can take a look at support.embarcadero.com/article/37740 to see the DK support status for each different RAD Studio version. Support for "de-supported" Embarcadero versions is subject to reasonable limits reflecting TatukGIS time and resource constraints. Our general guideline is to support RAD Studio releases for +/- 5 years after the launch date. Therefore, please plan on support for various RAD Studio versions being discontinued in accordance with the following schedule: RAD Studio 2007 - fall of 2013 (but should have been fall of 2012); TRIAL version support will be discontinued immediately RAD Studio 2009 - fall of 2013 RAD Studio 2010 - fall of 2014 RAD Studio XE - fall of 2015 RAD Studio XE2 - fall of 2016 RAD Studio XE3 - fall of 2017 To take this explanation a bit further, the Delphi development language recently contains interesting new features on which we wish to prioritize our efforts, as opposed to staying hooked to old compilers.
