<p>This document describes the changes made to the Dialyzer
application.</p>
+<section><title>Dialyzer 3.2</title>

+ <section><title>Fixed Bugs and Malfunctions</title>
+ <list>
+ <item>
+ <p> The check of bad type variables in type declarations
+ was mistakingly removed in Erlang/OTP 18, and is now
+ re-introduced. </p>

+ <list>
+ <item>
+ <p>
+ Analyzing modules with binary construction with huge
+ strings is now much faster. The compiler also compiles
+ such modules slightly faster.</p>
+ <p>
+ Own Id: OTP-14125 Aux Id: ERL-308 </p>
+ </item>
+ <item>
+ <p> The peak memory consumption is reduced. </p>
+ <p>
+ Own Id: OTP-14127</p>
+ </item>
+ <item>
+ <p> Warnings about unknown types are now also generated
+ for types not used by any function specification. </p>
+ <p>
+ Own Id: OTP-14218 Aux Id: OTP-14127 </p>
+ </item>
+ <item>
+ <p>TypEr has been removed as separate application and is
+ now a part of the Dialyzer application. Documentation for
+ TypEr has been added in the Dialyzer application.</p>
+ <p>
+ Own Id: OTP-14336</p>
+ </item>
+ <item>
+ <p>The format of debug information that is stored in BEAM
+ files (when <c>debug_info</c> is used) has been changed.
+ The purpose of the change is to better support other
+ BEAM-based languages such as Elixir or LFE.</p>
+ <p>All tools included in OTP (dialyzer, debugger, cover,
+ and so on) will handle both the new format and the
+ previous format. Tools that retrieve the debug
+ information using <c>beam_lib:chunk(Beam,
+ [abstract_code])</c> will continue to work with both the
+ new and old format. Tools that call
+ <c>beam_lib:chunk(Beam, ["Abst"])</c> will not work with
+ the new format.</p>
+ <p>For more information, see the description of
+ <c>debug_info</c> in the documentation for
+ <c>beam_lib</c> and the description of the
+ <c>{debug_info,{Backend,Data}}</c> option in the
+ documentation for <c>compile</c>.</p>
