-25.0.0 (TBD)
-============
-A new major release with critical updates.
-The new release includes a critical hotfix for 4D resamplings.
-The second major improvement is the inclusion of a first implementation of the X5 format (BIDS).
-The X5 implementation is currently restricted to reading/writing of linear transforms.
+25.0.0 (July 22, 2025)
+======================
+A new major release introducing critical fixes and important new functionality.
+Most notably, it includes a hotfix for 4D resampling (also backported to 24.1.4) and adds **experimental support for the X5 format** (*BIDS*).
+The X5 support enables I/O for linear and nonlinear transforms and includes partial support for transformation chains—marking a first step
+toward full *BIDS* interoperability.
+This release also drops support for *Python* 3.9 and earlier, aligning with modern *Python* standards and paving the way for future improvements.
