+This patch includes:
 
-* Added X_ref support as a memory-efficient alternative to precomputed LD matrices for summary-statistics workflows.
-* Added and refined robust post-filtering for colocalization and trait-specific uncolocalized events.
-* Improved computational efficiency for repeated matrix products in reference-panel workflows.
-* Improved plotting robustness for extreme association signals and coefficient or z-score displays.
-* Updated documentation and vignettes, including the bioinformatics pipeline vignette.
+* Fixed the CRAN-reported macOS arm64 test issue in the uCoS robustness tests.
+  The tests now use a stronger simulation setting and aligned inputs for
+  `get_robust_ucos()` and `get_ucos_evidence()`, so they no longer depend on
+  weak or platform-sensitive simulated signals.
+
+No R source code or package dependency changes were made for this CRAN-requested
+patch.

+## CRAN-requested macOS arm64 fix
+
+CRAN reported test failures for colocboost 1.0.8 on macOS arm64 and requested a
+correction before 2026-06-21. The failing test checked robust trait-specific
+uncolocalized event filtering and evidence calculation. The issue has been
+addressed by strengthening the simulation used in the test suite and by using
+matched `cb_obj` and `cb_res` inputs for the evidence check.
+
+CRAN also pointed to the M1mac check service for arm64 issues:
+https://www.stats.ox.ac.uk/pub/bdr/M1mac/README.txt. CRAN noted that this
+service runs a much older OS/toolchain and that toolchain differences often
+matter. This submission therefore fixes the test design itself, rather than
+relying on a platform-specific workaround.
