This is an update of the previously released R15B03. R15B03 contained a bug in ssl that affected accept calls with timeouts. Due to the widespread use of Erlang in i.e. webservers and other network application, we recommend everyone using R15B03 to take this update.

The previously announced incompatibility regarding crashdumps (that ERL_CRASH_DUMP_SECONDS have to be set to get any crash dump at all), is now limited to systems using heart. All other invocations of the Erlang VM will crashdump on fatal errors as they did in R15B02.

Note that systems using heart still has to define a maximum time for crashdumps using the ERL_CRASH_DUMP_SECONDS environment variable. See the readme file for further details.
