 ## [Unreleased]
 
+## [0.3.0] - 2026-10-01
+
+The third release. It gives a shorter spelling to everything the examples repeated, and takes no
+spelling away. `_r` writes an exact decimal, `27.3_r` being the `Rational` 273/10; a series takes
+plain numbers and `not_measured`; `number_of` reads the number a result holds; `describe` and
+`std::format` write results, units, dimensions and enumerations; `traced`, the `explain_*` twins and
+`trace_of` return a trace in one call; `DecimalRounding` names a rounding once; a `Measured` has
+throwing twins for its checked conversion, rounding and bounds check; and `yields<Q>` binds a
+formula to its result quantity. Every example is rewritten with these spellings and prints with
+`std::println`. GCC 14 is now the oldest supported GCC. Some changes break code written for 0.2.0;
+each is listed under Changed.
