 # Change Log
 
+## [1.1.0] - 2026-06-26
+
+### Changed
+
+- Adopted Swift's Approachable Concurrency upcoming features
+  (`NonisolatedNonsendingByDefault` and `InferIsolatedConformances`). The public
+  `async` entry points (`CIFP(url:)`, `CIFP(bytes:)`, and `linked()`) now run on
+  the caller's executor by default, and the streaming line readers are annotated
+  `@concurrent` so file and byte iteration keep running off the caller's
+  executor. No public signatures changed.
+
+### Internal
+
+- Removed the remaining `nonisolated(unsafe)` escape hatches: the two
+  header-parsing regexes are now compiled once per parse on the builder instead
+  of stored as shared unsafe statics.
+- Dropped a vestigial `@preconcurrency` from `import RegexBuilder`; the module is
+  fully `Sendable`-audited under Swift 6.
+
 ## [1.0.0] - 2026-01-17
