Check out the git tag OTP-28.0.3, 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.

# POTENTIAL INCOMPATIBILITIES

- Option max_handles can be configured for sshd running SFTP. The positive
  integer value limits amount of file handles opened for a connection (by
  default 4096 is used).

  Own Id: OTP-19701
  Application(s): ssh
  Related Id(s): PR-10157, CVE-2025-48041

- Avoid decoding KEX messages providing too many algorithms. This change does
  not introduce new limitation but assures it is enforced earlier in processing
  chain. Adjustments in error logging during handshake.

  Own Id: OTP-19741
  Application(s): ssh
  Related Id(s): PR-10162, CVE-2025-48040

- A new 'max_path' option is now available in the sshd configuration, allowing
  administrators to set the maximum allowable path length. By default, this
  value is set to 4096 characters.

  Own Id: OTP-19742
  Application(s): ssh
  Related Id(s): PR-10155, CVE-2025-48039

- Reject file handles exceeding size specified in RFCs (256 bytes).

# diameter-2.5.1

The diameter-2.5.1 application can be applied independently of other
applications on a full OTP 28 installation.

## Fixed Bugs and Malfunctions

- With this change message_cb callback will be called with updated state for
  processing 'ack' after 'send'.

# erts-16.0.3

The erts-16.0.3 application can be applied independently of other applications
on a full OTP 28 installation.

## Fixed Bugs and Malfunctions

- Update PCRE2 from 10.45 to 10.46. Fixes potential buffer read overflow on
  regular expressions with `(*scs:)` and `(*ACCEPT)` syntax combined.

  Own Id: OTP-19755
  Related Id(s): CVE-2025-58050

- Fixed bug that could cause crash in beam started with
  `erl -emu_type debug +JPperf true` with any type of tracing return from
  function.

# ssh-5.3.3

The ssh-5.3.3 application can be applied independently of other applications on
a full OTP 28 installation.

## Fixed Bugs and Malfunctions

- Option max_handles can be configured for sshd running SFTP. The positive
  integer value limits amount of file handles opened for a connection (by
  default 4096 is used).

# stdlib-7.0.3

Note! The stdlib-7.0.3 application _cannot_ be applied independently of other
applications on an arbitrary OTP 28 installation.

       On a full OTP 28 installation, also the following runtime
       dependency has to be satisfied:
       -- erts-16.0.3 (first satisfied in OTP 28.0.3)

## Fixed Bugs and Malfunctions

- Update PCRE2 from 10.45 to 10.46. Fixes potential buffer read overflow on
  regular expressions with `(*scs:)` and `(*ACCEPT)` syntax combined.
