Check out the git tag OTP-28.1.1, 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.

OTP-28.1.1

Improvements and New Features

  • When building OTP, some applications may be skipped due to lacking dependencies, or due to user choice. Such skipped applications are excluded from the docs build step and a placeholder page is displayed in their stead.

Own Id: OTP-19771
Related Id(s): ERIERL-1251, PR-10194

diameter-2.5.2

The diameter-2.5.2 application can be applied independently of other applications on a full OTP 28 installation.

Fixed Bugs and Malfunctions

  • Added documentation about 'proxy' and 'resend' options in diameter:handle_request/3

erts-16.1.1

The erts-16.1.1 application can be applied independently of other applications on a full OTP 28 installation.

Fixed Bugs and Malfunctions

  • Fixed the erl documentation of the default timewarp mode used.

Own Id: OTP-19790
Related Id(s): PR-9970

  • The erlang:suspend_process() BIFs failed to suspend processes currently executing on dirty schedulers.

ssl-11.4.1

Note! The ssl-11.4.1 application cannot be applied independently of other applications on an arbitrary OTP 28 installation.

   On a full OTP 28 installation, also the following runtime
   dependencies have to be satisfied:

   -- public_key-1.18.3 (first satisfied in OTP 28.1)

Fixed Bugs and Malfunctions

  • Fixed so that sending of application data will adhere to max_fragment_length. This was broken in OTP-27 release by an optimization.
