+Patch Package: OTP 22.3.4.11
+Git Tag: OTP-22.3.4.11
+Date: 2020-10-02
+Trouble Report Id: OTP-16815, OTP-16847, OTP-16856, OTP-16866,
+ OTP-16870, OTP-16874, OTP-16904, OTP-16906
+Seq num: ERIERL-500, ERIERL-532, ERL-1301, ERL-1355,
+ ERL-1356
+System: OTP
+Release: 22
+Application: erts-10.7.2.4, mnesia-4.16.3.1,
+ os_mon-2.5.1.1, ssh-4.9.1.2
+Predecessor: OTP 22.3.4.10
+
+ 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.
+
+
+ Full runtime dependencies of erts-10.7.2.4: kernel-6.5.1, sasl-3.3,
+ stdlib-3.5
+
+
+ ---------------------------------------------------------------------
+ --- 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,
