+ <p>
+ 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.</p>

+ Fix SIGUSR1 crashdump generation</p>
+ <p>
+ Do not generate a core when a crashdump is asked for.</p>
+ <p>
+ Own Id: OTP-13997</p>
+ </item>
+ <item>
+ <p>The new functions in <c>code</c> that allows loading
+ of many modules at once had a performance problem. While
+ executing a helper function in the <c>erl_prim_loader</c>
+ 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.</p>
+ <p>The functions affected of this problem were:
+ <c>atomic_load/1</c>, <c>ensure_modules_loaded/1</c>, and
+ <c>prepare_loading/1</c>.</p>
