A new beta version with first attributes support is available here: https://www.skipper18.com/support/402/downloads-skipper-beta
Please test it and let us know your experiences. We had to rewrite a lot of parts of PHP code parsers/generators/mergers and improved a lot of areas of code formating.
All our unit tests and testing projects are now green but there can be still a lot of bugs. So please report anything unusual.
Thanks
