We have an exciting announcement, a new FIT Beta SDK!
This Beta SDK contains a new FIT feature that allows developers to create custom data that is self-describing. The development of this new feature required a breaking change in the FIT SDK so we incremented the FIT Protocol version to 2.0. In order to integrate the SDK, just follow your normal upgrade path for any other FIT update. If you wish to decode the new custom data then follow the code examples provided in all languages, if you do not wish to decode the custom data it is still strongly recommended to update, as FIT 1.0 decoders cannot decode FIT 2.0 files.
The FIT Protocol document has been updated to describe the new feature, and there are examples of how to encode and decode using the new feature for all languages.
The new SDK still allows developers to write 1.0 compliant FIT files as long as the developer is not trying to use the new incompatible features. (It is strongly recommended to only write 2.0 files if you are using 2.0 features).

We also have some C++ speed improvements coming in a beta-2 next week, stay tuned.
