Check out the git tag OTP-24.3.4.15, 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 -------------------------------------
---------------------------------------------------------------------
OTP-18897 Application(s): ssh
With this change (being response to CVE-2023-48795),
ssh can negotiate "strict KEX" OpenSSH extension with
peers supporting it; also
'chacha20-poly1305@REDACTED' algorithm becomes a
less preferred cipher.
If strict KEX availability cannot be ensured on both
connection sides, affected encryption modes(CHACHA and
CBC) can be disabled with standard ssh configuration.
This will provide protection against vulnerability, but
at a cost of affecting interoperability. See
Configuring algorithms in SSH.

--- OTP-24.3.4.15 ---------------------------------------------------
---------------------------------------------------------------------
--- Improvements and New Features ---
OTP-18896 Application(s): otp
Updated copyright and license information.
---------------------------------------------------------------------
--- asn1-5.0.18.2 ---------------------------------------------------
---------------------------------------------------------------------
The asn1-5.0.18.2 application can be applied independently of other
applications on a full OTP 24 installation.
--- Fixed Bugs and Malfunctions ---
OTP-18844 Application(s): asn1
Fix benign warning from gcc 11 about mismatching call
to free().
Full runtime dependencies of asn1-5.0.18.2: erts-11.0, kernel-7.0,
stdlib-3.13
---------------------------------------------------------------------
--- erl_interface-5.2.2.1 -------------------------------------------
---------------------------------------------------------------------
The erl_interface-5.2.2.1 application can be applied independently of
other applications on a full OTP 24 installation.
--- Improvements and New Features ---
OTP-18877 Application(s): erl_interface, erts
Replaced old md5 implementation with an implementation
from OpenSSL.
---------------------------------------------------------------------
--- erts-12.3.2.15 --------------------------------------------------
---------------------------------------------------------------------
Note! The erts-12.3.2.15 application *cannot* be applied
independently of other applications on an arbitrary OTP 24
installation.
On a full OTP 24 installation, also the following runtime
dependency has to be satisfied:
-- kernel-8.3 (first satisfied in OTP 24.3)
--- Fixed Bugs and Malfunctions ---
OTP-18802 Application(s): erts
Fix faulty debug assert when page size is larger than
16kb, like on PowerPC. Did crash debug VM directly at
start.
OTP-18885 Application(s): erts
Related Id(s): GH-7834, GH-7890, PR-7915
On OTP 24 and OTP 25, incoming distributed messages
larger than 64 KiB sent using an alias leaked memory if
the alias had been removed prior to entering the node.
This issue was not present on OTP 26.
Incoming distributed messages larger than 64 KiB sent
using an alias which had been removed on the receiving
node could crash the node. This crash was quite
unlikely on OTP 24 and OTP 25, but very likely on OTP
26.
'DOWN' signals with exit reason larger than 64 KiB
directed towards a process on a node with a not
matching creation leaked memory on the receiving node.
Such signals should however be very rare.
OTP-18902 Application(s): erts
Removed unnecessary PCRE source tar-ball.
--- Improvements and New Features ---
OTP-18830 Application(s): erts
Related Id(s): PR-7823
Removed unnecessary regexp library used when generating
yielding BIFs.
OTP-18877 Application(s): erl_interface, erts
Replaced old md5 implementation with an implementation
from OpenSSL.
OTP-18899 Application(s): erts
Removed unused makewhatis script.
Full runtime dependencies of erts-12.3.2.15: kernel-8.3, sasl-3.3,
stdlib-3.13
---------------------------------------------------------------------
--- mnesia-4.20.4.4 -------------------------------------------------
---------------------------------------------------------------------
The mnesia-4.20.4.4 application can be applied independently of other
applications on a full OTP 24 installation.
--- Fixed Bugs and Malfunctions ---
OTP-18850 Application(s): mnesia
mnesia:add_table_copy/3 no longer fails with reason
system_limit when the node is starting.
Full runtime dependencies of mnesia-4.20.4.4: erts-9.0, kernel-5.3,
stdlib-3.4
---------------------------------------------------------------------
--- ssh-4.13.2.4 ----------------------------------------------------
---------------------------------------------------------------------
The ssh-4.13.2.4 application can be applied independently of other
applications on a full OTP 24 installation.
--- Fixed Bugs and Malfunctions ---
OTP-18869 Application(s): ssh
Related Id(s): GH-7571, PR-7849
With this change, connection handler does not execute
socket operations until it becomes socket owner.
Previously errors could occur if connection handler
tried to work with socket whose owner exited.
OTP-18897 Application(s): ssh
