<p>This document describes the changes made to the SASL application.</p>
+<section><title>SASL 3.2</title>
+
+ <section><title>Improvements and New Features</title>
+ <list>
+ <item>
+ <p>A new logging API is added to Erlang/OTP, see the
+ <seealso
+ marker="kernel:logger"><c>logger(3)</c></seealso> manual
+ page, and section <seealso
+ marker="kernel:logger_chapter">Logging</seealso> in the
+ Kernel User's Guide.</p>
+ <p>Calls to <c>error_logger</c> are automatically
+ redirected to the new API, and legacy error logger event
+ handlers can still be used. 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>

+ The old and out-dated "Status Inspection" tool (modules
+ <c>si</c> and <c>si_sasl_sup</c>) is removed.</p>

+ <p>
+ When creating the release tar file, systools now includes
+ sys.config.src if it exists in the
+ $ROOT/releases/&lt;vsn&gt;/ directory. This is to allow
+ adjustments, e.g. resolving environment variables, after
+ unpacking the release, but before installing it. This
+ functionality requires a custom tool which uses
+ sys.config.src as input and creates a correct sys.config
+ file.</p>
