 ## [Unreleased]
 
+## [baikai 0.6.0.1] - 2026-08-30
+
+### Fixed
+
+- widened the `http-client-tls` bound to admit 0.4. The 0.4 API retains the
+  manager functions this package uses and belongs to the same TLS 2.x / Crypton
+  1.1 dependency cohort as baikai 0.6; the old `^>=0.3` cap made baikai 0.6
+  impossible to solve in applications that require Crypton 1.1.
+
+## [baikai-claude 0.6.0.1] - 2026-08-30
+
+### Fixed
+
+- widened the `http-client-tls` bound to admit 0.4, allowing applications that
+  require Crypton 1.1 to solve the dependency set.
