Check out the git tag OTP-27.1.3, 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-1.27.4

The common_test-1.27.4 application can be applied independently of other
applications on a full OTP 27 installation.

Fixed Bugs and Malfunctions

• With this change, cth_surefire hook module handles group path reduction for a
  skipped group. This fixes a bug manifesting with improper group path for a
  group executed after a group which was skipped.

  Related Id(s): ERIERL-1157, PR-9080

Improvements and New Features

• With this change, prefix option can be specified in cth_conn_log option list.
  Option allows to specify how much of additional information is added in raw
  log output.

Fixed Bugs and Malfunctions

• In rare circumstances, the destructive tuple update optimization could be
  applied when it was unsafe.

on a full OTP 27 installation.

Fixed Bugs and Malfunctions

kernel-10.1.2

Note! The kernel-10.1.2 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

• On windows the socket:recv could return with success ({ok, Data}) even though
  not all data had been read.

public_key-1.16.4

The public_key-1.16.4 application can be applied independently of other
applications on a full OTP 27 installation.

Fixed Bugs and Malfunctions

• If both ext-key-usage and key-usage are defined for a certificate it
  should be checked that these usages are consistent with each other. This will
  have the affect that such certificates where the ext-key-usages is marked as
  critical and the usages is consistent with the key-use it can be considered
  valid without mandatory application specific checks for the ext-key-useage
  extension.

  only the public EDDSA key.

   -- public_key-1.16.4 (first satisfied in OTP 27.1.3)

Fixed Bugs and Malfunctions

• Avoid generating an internal alert for case that should have been an orderly
  shutdown by the supervisor.

• If present, extended key-usage TLS (SSL) role check (pk-clientAuth,
  pk-serverAuth) should always be performed for peer-cert. An intermediate CA
  cert may relax the requirement if AnyExtendedKeyUsage purpose is present.

  In OTP-25.3.2.8, OTP-26.2 and OTP-27.0 these requirements became too relaxed.
  There where two problems, firstly the peer cert extension was only checked if
  it was marked critical, and secondly the CA cert check did not assert the
  relaxed AnyExtendedKeyUsage purpose.

  This could result in that certificates might be misused for purposes not
  intended by the certificate authority.

  Thanks to Bryan Paxton for reporting the issue.

Improvements and New Features

• Back port certificate_authorities option for TLS-1.3 servers to pre TLS-1.3
  servers to enable them to disable the sending of certificate authorities in
  their certificate request. This will have same affect as the the TLS-1.3
  server option although it is handled by a different mechanism in these
  versions, where the functionality is described to be more of a guidance,
  although some pre TLS clients have proven to make it mandatory as in TLS-1.3
  extension handling.
