 # Changelog
 All notable changes to this project are documented in this file.
 
+## [4.0.1] - 2025-11-21
+### Changed
+- Applied nrfx 4.0 changes to existing samples for all drivers:
+    - aligned samples to extracted control blocks and new method of handling interrupts,
+    - replaced nrfx error codes with errno codes,
+    - aligned samples to other API changes in the nrfx_gppi helper layer and the SAADC driver.
+- Changed UARTE instance used for console on nRF54L15 DK to UARTE30 as this is the instance used in all other samples. The change was not applied to SPIM-SPIS examples due to conflicting pins.
+
+## [3.14.0] - 2025-08-22
+### Added
+- Added support for the nRF54L15 DK to all existing samples except for the RNG sample.
+- Added sample for the CRACEN driver.
+
+### Changed
+- Divided existing loopback definitions in `common/nrfx_example.h` into individual header files for each board in `common/boards`.
+- Moved pin definitions from individual samples to board header files in `common/boards`.
+
 ## [3.8.0] - 2024-10-17
 ### Changed
 - Aligned Kconfig definitions to DPPIC multi-instance support in the GPPI and SAADC driver samples.
