 Check out the git tag OTP-22.1.6, 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.

 ---------------------------------------------------------------------
 --- compiler-7.4.8 --------------------------------------------------
 ---------------------------------------------------------------------

 The compiler-7.4.8 application can be applied independently of other
 applications on a full OTP 22 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16219    Application(s): compiler, erts
               Related Id(s): ERL-1076

               The compiler could do an unsafe optimization of
               receives, which would cause a receive to only scan part
               of the message queue.

               This bug fix in the compiler fixes a bug in the socket
               module.


 Full runtime dependencies of compiler-7.4.8: crypto-3.6, erts-9.0,
 hipe-3.12, kernel-4.0, stdlib-2.5


 ---------------------------------------------------------------------
 --- crypto-4.6.2 ----------------------------------------------------
 ---------------------------------------------------------------------

 The crypto-4.6.2 application can be applied independently of other
 applications on a full OTP 22 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16242    Application(s): crypto
               Related Id(s): ERL-1078

               The AEAD tag was not previously checked on decrypt with
               chacha20_poly1305


 Full runtime dependencies of crypto-4.6.2: erts-9.0, kernel-5.3,
 stdlib-3.4


 ---------------------------------------------------------------------
 --- erts-10.5.4 -----------------------------------------------------
 ---------------------------------------------------------------------

 The erts-10.5.4 application can be applied independently of other
 applications on a full OTP 22 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16219    Application(s): compiler, erts
               Related Id(s): ERL-1076

               The compiler could do an unsafe optimization of
               receives, which would cause a receive to only scan part
               of the message queue.

               This bug fix in the compiler fixes a bug in the socket
               module.


  OTP-16241    Application(s): erts
               Related Id(s): ERL-1076, OTP-16219

               Fix bug where the receive marker used by the runtime to
               do the receive queue optimization could be incorrectly
               set. The symptom of this would be that a message that
               should match in a receive never matches.

               The bug requires the OTP-22 compiler and multiple
               selective receives to trigger. See OTP-16219 for
               details about the bug fix in the compiler.


 Full runtime dependencies of erts-10.5.4: kernel-6.1, sasl-3.3,
 stdlib-3.5


 ---------------------------------------------------------------------
 --- snmp-5.4.3 ------------------------------------------------------
 ---------------------------------------------------------------------

 The snmp-5.4.3 application can be applied independently of other
 applications on a full OTP 22 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16228    Application(s): snmp
               Related Id(s): ERIERL-427

               Agent discovery cleanup. If there is no receiver of
               INFORM then #state.reqs in snmpa_net_if keeps on
               growing for DISCOVERY.


 Full runtime dependencies of snmp-5.4.3: crypto-3.3, erts-6.0,
 kernel-3.0, mnesia-4.12, runtime_tools-1.8.14, stdlib-2.5
