Erlang/OTP 19.1 is a service release on the 19 track with mostly bug fixes,
but is does contain a number of new features and characteristics
as well.

Some highlights of the release are:

   - erts: Improved dirty scheduler support. A purge of a module will not
   have to wait for completion of all ongoing dirty NIF calls.
   - erts: Improved accuracy of timeouts on MacOS X.
   - kernel: Add net_kernel:setopts/2 and net_kernel:getopts/2 to control
   options for distribution sockets in runtime.
   - asn1: Compiling multiple ASN.1 modules in the same directory with
   parallel make (make -j) should now be safe.
   - httpd: support for PUT and DELETE in mod_esi
   - ~30 contributions since 19.0
