The major improvement is that if a code upgrade - fails because the <c>on_load</c> function fails, the - previous version of the module will now be retained.</p> - <p> - Own Id: OTP-12593</p> - </item> - <item> - <p><c>rpc:call()</c> and <c>rpc:block_call()</c> would - sometimes cause an exception (which was not mentioned in - the documentation).

It - does not have monoticity guarantees, but should on most - OS's expose a monotonous time.</p> - <p> - Own Id: OTP-12908</p> - </item> - <item> - <p> - The os:cmd call has been optimized on unix platforms to - be more performant as the number of schedulers increase.</p> - <p> - Own Id: OTP-13089</p> - </item> - <item> - <p>New functions that can load multiple functions at once - have been added to the '<c>code</c>' module. The - functions are <c>code:atomic_load/1</c>, - <c>code:prepare_loading/1</c>, - <c>code:finish_loading/1</c>, and - <c>code:ensure_modules_loaded/1</c>.</p> - <p> - Own Id: OTP-13111</p> - </item> - <item> - <p> - The code path cache feature turned out not to be very - useful in practice and has been removed. If an attempt is - made to enable the code path cache, there will be a - warning report informing the user that the feature has - been removed.</p> - <p> - Own Id: OTP-13191</p> - </item> - <item> - <p>When an attempt is made to start a distributed Erlang - node with the same name as an existing node, the error - message will be much shorter and easier to read than - before. Example:</p> - <p><c>Protocol 'inet_tcp': the name somename@somehost - seems to be in use by another Erlang node</c></p> - <p> - Own Id: OTP-13294</p> - </item> - <item> - <p> - The output of the default error logger is somewhat - prettier and easier to read. The default error logger is - used during startup of the OTP system. If the start-up - fails, the output will be easier to read.</p> - <p> - Own Id: OTP-13325</p> - </item> - <item> - <p>The functions <c>rpc:safe_multi_server_call/2,3</c> - that were deprecated in R12B have been removed.</p> - <p> - *** POTENTIAL INCOMPATIBILITY ***</p> - <p> - Own Id: OTP-13449</p> - </item> - <item> - <p> - Update the error reasons in dist_util, and show them in - the logs if net_kernel:verbose(1) has been called.</p> - <p> - Own Id: OTP-13458</p> - </item> - <item> - <p> - Experimental support for Unix Domain Sockets has been - implemented.
