store( &version ) "%KeymanVersion%" VERSION %KeymanVersion%
The VERSION statement was added to Keyman 3.0 to allow later versions to easily distinguish what version of Keyman the keyboard was written for and handle it as such. The VERSION statement is required. For new keyboards, use 6.0 as the version number.
The use statement was introduced in Keyman 3.0. Keyman 7.0 will compile Keyman 6.0 keyboards without modification, but you must specify version 7.0 for keyboards that make use of version 6.0 features.
