Check out the git tag OTP-22.3.4.11, 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.
---------------------------------------------------------------------
--- erts-10.7.2.4 ---------------------------------------------------
---------------------------------------------------------------------
Note! The erts-10.7.2.4 application *cannot* be applied independently
of other applications on an arbitrary OTP 22 installation.
On a full OTP 22 installation, also the following runtime
dependency has to be satisfied:
-- kernel-6.5.1 (first satisfied in OTP 22.2)
--- Fixed Bugs and Malfunctions ---
OTP-16847 Application(s): erts
Related Id(s): ERL-1301
inet:setopts([{active,once}]) wakes up IO polling
thread unnecessarily, leading to lock contention and
visibly higher CPU utilization.
OTP-16866 Application(s): erts
Related Id(s): ERL-1355
The documentation of statistics(run_queue) erroneously
stated that it returns the total length of all normal
run queues when it is the total length of all normal
and dirty CPU run queues that is returned. The
documentation has been updated to reflect the actual
behavior.
OTP-16870 Application(s): erts
Two bugs in the ERTS internal thread wakeup
functionality have been fixed. These bugs mainly hit
when all threads in the system tried to go to sleep.
When the bugs were triggered, certain operations were
delayed until a thread woke up due to some other
reason. Most important operations effected were code
loading, persistent term updates, and memory
deallocation.
OTP-16874 Application(s): erts
Related Id(s): ERL-1356, PR-2763
Fixed bug in ets:select_replace/2 on compressed tables
that could produce faulty results or VM crash. Bug
exists since OTP 20.
--- Improvements and New Features ---
OTP-16856 Application(s): erts
As of OTP 22, the allocator specific memory carrier
pools were replaced by a node global carrier pool. This
unfortunately caused substantial memory fragmentation
in some cases due to long lived data being spread into
carriers used by allocators mainly handling short lived
data.
A new command line argument +M<S>cp has been introduced
with which one can enable the old behavior as well as
configuring other behaviors for the carrier pools. In
order to configure the old behavior, with allocator
specific carrier pools for all allocators, pass +Mucp :
(including the colon character) as a command line
argument to erl when starting the Erlang system.
The default configuration for carrier pools will be
changed to +Mucp : some time in the future, but not in
this patch.

---------------------------------------------------------------------
--- mnesia-4.16.3.1 -------------------------------------------------
---------------------------------------------------------------------
The mnesia-4.16.3.1 application can be applied independently of other
applications on a full OTP 22 installation.
--- Improvements and New Features ---
OTP-16815 Application(s): mnesia
Related Id(s): ERIERL-500
Fixed crash during startup, which could happen if a
table was deleted on another node.
Full runtime dependencies of mnesia-4.16.3.1: erts-9.0, kernel-5.3,
stdlib-3.4
---------------------------------------------------------------------
--- os_mon-2.5.1.1 --------------------------------------------------
---------------------------------------------------------------------
The os_mon-2.5.1.1 application can be applied independently of other
applications on a full OTP 22 installation.
--- Improvements and New Features ---
OTP-16906 Application(s): os_mon
Related Id(s): ERIERL-532
The configuration parameter
memsup_improved_system_memory_data has been introduced.
It can be used to modify the result returned by
memsup:get_system_memory_data(). For more information
see the memsup documentation.
Note that the configuration parameter is intended to be
removed in OTP 24 and the modified result is intended
to be used as of OTP 24.
Full runtime dependencies of os_mon-2.5.1.1: erts-6.0, kernel-3.0,
sasl-2.4, stdlib-2.0
---------------------------------------------------------------------
--- ssh-4.9.1.2 -----------------------------------------------------
---------------------------------------------------------------------
Note! The ssh-4.9.1.2 application *cannot* be applied independently
of other applications on an arbitrary OTP 22 installation.
On a full OTP 22 installation, also the following runtime
dependency has to be satisfied:
-- crypto-4.6.4 (first satisfied in OTP 22.2.2)
--- Fixed Bugs and Malfunctions ---
OTP-16904 Application(s): ssh
Fix decoder bug.
Full runtime dependencies of ssh-4.9.1.2: crypto-4.6.4, erts-9.0,
kernel-5.3, public_key-1.6.1, stdlib-3.4.1
