Check out the git tag OTP-27.2.1, and build a full OTP system including
documentation. Apply one or more applications from this build as patches to your
installation using the 'otp_patch_apply' tool. For information on install
requirements, see descriptions for each application version below.

common_test-1.27.6

The common_test-1.27.6 application can be applied independently of other
applications on a full OTP 27 installation.

Fixed Bugs and Malfunctions

• Common test will now not crash when running tests with otp26 and earlier,
  while having previous test resuts from otp27.
