CHANGELOG.md

 - Added new module `snabbkaffe_diff` that helps to compare large lists
 - Added a new macro `?defer_assert(...)` that allows the run stage to continue after encountering a failure, and fails the testcase in the check stage instead.
 
+### Fixes
+- Quote a new reserved word (`maybe`) for compatibility with OTP27
+
 ## 1.0.9
 ### Features
 - Now it is possible to redefine what `?snk_kind` macro translates to in prod mode by defining `SNK_PROD_KIND` macro.
