 --- erts-10.7.2.1 ---------------------------------------------------
 ---------------------------------------------------------------------

 Note! The erts-10.7.2.1 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-16596    Application(s): erts
               Related Id(s): ERL-1105, PR-2606

               Fixed bug in erl_crash.dump generation that could cause
               a SEGV core dump if a recently cancelled timer was
               found.


  OTP-16639    Application(s): erts
               Related Id(s): ERL-1236

               The functionality utilized by BIFs for temporary
               disabling of garbage collection while yielding could
               cause system task queues to become inconsistent on a
               process executing such a BIF. Process system tasks are
               for example utilized when purging code, garbage
               collecting literal data, and when issuing an ordinary
               garbage collection from another process.

               The bug does not trigger frequently. Multiple code
               purges in direct sequence makes it more likely that
               this bug is triggered. In the cases observed, this has
               resulted in a hanging code purge operation.


  OTP-16654    Application(s): erts
               Related Id(s): ERL-1242

               SCTP and UDP recv/2,3 hangs indefinitely if socket is
               closed while recv is called (socket in passive mode).

 ---------------------------------------------------------------------
 --- kernel-6.5.2.1 --------------------------------------------------
 ---------------------------------------------------------------------

 Note! The kernel-6.5.2.1 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:
       -- erts-10.6 (first satisfied in OTP 22.2)


 --- Fixed Bugs and Malfunctions ---

  OTP-16627    Application(s): kernel
               Related Id(s): PR-2601

               Fix bug in application:loaded_applications/0 that could
               cause it to fail with badarg if for example a
               concurrent upgrade/downgrade is running.

 --- megaco-3.18.8.1 -------------------------------------------------
 ---------------------------------------------------------------------

 The megaco-3.18.8.1 application can be applied independently of other
 applications on a full OTP 22 installation.

 --- Fixed Bugs and Malfunctions ---

  OTP-16631    Application(s): megaco
               Related Id(s): ERIERL-491

               The mini parser could not properly decode some IPv6
               addresses.
