+0.2.9
+
+- Make package-build tests independent of the directory from which raco test is invoked.
+- Run Rash smoke tests in an isolated temporary directory and capture expected command output.
+- Keep successful tests silent under raco test --drdr; unexpected failures still escape normally.
+- Isolate environment-variable tests with current-environment-variables instead of mutating the process environment.
+- Declare linea explicitly as a build dependency because the Rash test modules use its reader.
+
 0.2.7
 
 - Fix package setup regression in the Racket test suite after the raco command/procedure split.
