+# `ttc-haskell` `1.5.0.1` Release Notes
+
+Date
+: 2026-01-10
+
+## Overview
+
+TTC, an initialism of _Textual Type Classes_, is a library that provides the
+following functionality:
+
+* The `Textual` type class is used to convert between common textual data
+  types.  It can be used to write functions that accept or return values of
+  any of these textual data types.
+* The `Render` type class is used to render a value as text.  Avoid bugs by
+  only using `Show` for debugging/development purposes.
+* The `Parse` type class is used to parse a value from text.  Unlike `Read`,
+  it has support for error messages.
+* Validate constants at compile-time using `Parse` instances.
+
+See the [README][] for details.

+### Compatibility
