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.

# kernel-10.2.1

Note! The kernel-10.2.1 application _cannot_ be applied independently of other
applications on an arbitrary OTP 27 installation.

       On a full OTP 27 installation, also the following runtime
       dependency has to be satisfied:
       -- erts-15.1 (first satisfied in OTP 27.1)

## Fixed Bugs and Malfunctions

- Fix the default group_leader to reply `{error,request}` on invalid I/O
  requests instead of crashing.

  This bug was introduced in Erlang/OTP 27.2.

# ssh-5.2.6

The ssh-5.2.6 application can be applied independently of other applications on
