  Check out the git tag OTP-19.1.6, 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.

  --- erts-8.1.1 ------------------------------------------------------

  Note! The erts-8.1.1 application can *not* be applied independently
        of other applications on an arbitrary OTP 19 installation.

        On a full OTP 19 installation, also the following runtime
        dependency has to be satisfied:
        -- sasl-3.0.1 (first satisfied in OTP 19.1)

  --- Fixed Bugs and Malfunctions ---

   OTP-13956    Application(s): erts
                Related Id(s): ERL-133, ERL-262

                The emulator got a dynamic library dependency towards
                libsctp, which on Linux was not intended since the
                emulator there loads and resolves the needed sctp
                functions in runtime. This has been fixed and a
                configure switch --enable-sctp=lib has been added for
                those who want such a library dependency.

                Fix SIGUSR1 crashdump generation

                Do not generate a core when a crashdump is asked for.

   OTP-14009    Application(s): erts

                The new functions in code that allows loading of many
                modules at once had a performance problem. While
                executing a helper function in the erl_prim_loader
                process, garbage messages were produced. The garbages
                messages were ignored and ultimately discarded, but
                there would be a negative impact on performance and
                memory usage. The number of garbage message depended on
                both the number of modules to be loaded and the length
                of the code path.

                The functions affected of this problem were:
                atomic_load/1, ensure_modules_loaded/1, and
