Release Highlights#
Bugfixes and minor improvements.
Deprecation Notes#
The RAIL 2.x API is planned for deprecation in the 25Q4-GA release (December 2025). At that time, the new RAIL 3.0 API will be released for all supported chips along with a RAIL 2.x compatibility layer and migration guide.
The goal of this new API is to get rid of some unused features, add better support for concurrent listening use cases, and to simplify channel and PA configurations.
The migration is intended to be straight forward and simple for the majority of customers. However, in some cases manual help might be required to ease this transition.
Note: RAIL 3.0 API is in evaluation in sl_rail_*.h files, though subject to change, and the RAIL library has RAIL 3.0 symbols alongside RAIL 2.x, with some stacks and RAIL apps having started to use it in 25Q2-GA.
