The latest version is the first version that supports Delphi XE7.
There is nothing really new about the formatter code. But the new release can be installed even if you don’t have the official GExperts installer (yet). This is an extract from the readme file:
** Installing without an official installer ** With two Delphi Releases per year and Erik Berry being busy otherwise, new GExperts releases have been lagging behind. So in case there is no official GExperts installer yet, these are the steps to install the experimental version by hand: 1. Create a suitable GExperts directory. It doesn't have to be a subdirectory of %ProgramFiles% but may be anywhere, even on a network share if you are sure this share will always be available. 2. Extract all files from the ZIP somewhere 3. Copy all files from the extracted directory to the GExperts directory. (Do *NOT* copy the subdirectories!) 4. Copy the appropriate GExperts DLL from one of the subdirectories EditorExpert or RegularExpert to the GExperts directory. 5. Copy the files from the subdirectory FromRegularRelease to the GExperts directory. 6. Copy the appropriate cmd from the install subdirectory. To the GExperts directory. 7. Make sure that the Delphi IDE is not running 8. Run the cmd file. It will register the GExperts dll with the Delphi IDE. 9. Start Delphi and check that the new GExperts DLL has been loaded by opening the GExperts About dialog. In theory it is possible to install GExperts for all Delphi versions into the same GExperts directory. But be warned: This has not been tested thoroughly.
