 This file was introduced starting Kani 0.23.0, so it only contains changes from version 0.23.0 onwards.
 
+## [0.53.0]
+
+### Major Changes
+* The `--visualize` option is being deprecated and will be removed in a future release. Consider using the `--concrete-playback` option instead.
+* The `-Z ptr-to-ref-cast-checks` option is being introduced to check pointer validity when casting raw pointers to references. The feature is currently behind an unstable flag but is expected to be stabilized in a future release once remaining performance issues have been resolved.
+* The `-Z uninit-checks` option is being introduced to check memory initialization. The feature is currently behind an unstable flag and also requires the `-Z ghost-state` option.
+
+### Breaking Changes
+* Remove support for the unstable argument `--function` by @celinval in https://github.com/model-checking/kani/pull/3278
+* Remove deprecated `--enable-stubbing` by @celinval in https://github.com/model-checking/kani/pull/3309
