It is, however, recommended - to use the Logger API directly when writing new code.</p> - <p>Notice the following potential incompatibilities:</p> - <list> <item><p>Kernel configuration parameters - <c>error_logger</c> still works, but is overruled if the - default handler's output destination is configured with - Kernel configuration parameter <c>logger</c>.</p> <p>In - general, parameters for configuring error logger are - overwritten by new parameters for configuring - Logger.</p></item> <item><p>The concept of SASL error - logging is deprecated, meaning that by default the SASL - application does not affect which log events are - logged.</p> <p>By default, supervisor reports and crash - reports are logged by the default Logger handler started - by Kernel, and end up at the same destination (terminal - or file) as other standard log event from Erlang/OTP.</p> - <p>Progress reports are not logged by default, but can be - enabled with the Kernel configuration parameter - <c>logger_progress_reports</c>.</p> <p>To obtain - backwards compatibility with the SASL error logging - functionality from earlier releases, set Kernel - configuration parameter <c>logger_sasl_compatible</c> to - <c>true</c>. This prevents the default Logger handler - from logging any supervisor-, crash-, or progress - reports. Instead, SASL adds a separate Logger handler - during application start, which takes care of these log - events. The SASL configuration parameters - <c>sasl_error_logger</c> and <c>sasl_errlog_type</c> - specify the destination (terminal or file) and severity - level to log for these events.</p></item></list> - <p> - *** POTENTIAL INCOMPATIBILITY ***</p> - <p> - Own Id: OTP-13295</p> - </item> - <item> - <p> - The function <c>inet:i/0</c> has been documented.</p> - <p> - Own Id: OTP-13713 Aux Id: PR-1645 </p> - </item> - <item> - <p> - Typespecs for <c>netns</c> and <c>bind_to_device</c> - options have been added to <c>gen_tcp</c>, <c>gen_udp</c> - and <c>gen_sctp</c> functions.</p> - <p> - Own Id: OTP-14359 Aux Id: PR-1816 </p> - </item> - <item> - <p> - New functionality for implementation of alternative - carriers for the Erlang distribution has been introduced. - This mainly consists of support for usage of distribution - controller processes (previously only ports could be used - as distribution controllers).
