<p>This document describes the changes made to the Dialyzer
application.</p>
+<section><title>Dialyzer 2.4.4</title>
+
+ <section><title>Fixed Bugs and Malfunctions</title>
+ <list>
+ <item>
+ <p>
+ Update results of race_SUITE/extract_translations Update
+ results of small_SUITE/flatten Add codec_can and
+ list_to_bitstring tests Fix bug when reporting unused
+ functions Update Dialyzer r9c_suite results Fix dialyzer
+ warning on default clause for binary comprehension
+ (Thanks to Ivan Dubrov)</p>
+ <p>
+ Own Id: OTP-9483</p>
+ </item>
+ <item>
+ <p>
+ Fix server loop detection</p>
+ <p>
+ Dialyzer does not normally emit warnings for functions
+ that implement non-terminating server loops. This
+ detection failed when some of the elements in an SCC
+ terminated normally (being for example list
+ comprehensions or other generic anonymous functions that
+ were included in the SCC). This patch fixes that.</p>
+ <p>
+ Own Id: OTP-9489</p>
+ </item>
+ <item>
+ <p>
+ Add a proplist() type</p>
+ <p>
+ Recently I was adding specs to an API and found that
+ there is no canonical proplist() type defined. (Thanks to
+ Ryan Zezeski)</p>
+ <p>
+ Own Id: OTP-9499</p>
+ </item>
+ <item>
+ <p>
+ Suppress some warnings about generation of non-returning
+ funs</p>
+ <p>
+ No warnings are emitted for funs that are non-returning
+ when the function that generates them has a contract that
+ specifies that it will return such a non-returning fun.</p>
+ <p>
+ Enhance Dialyzer's inference on comparisons</p>
+ <p>
+ This patch makes Dialyzer aware of Erlang's total
+ ordering of terms, enabling discrepancy detection in
+ cases where e.g. integer() &lt; tuple() is treated as a
+ comparison that might also return false (when it is
+ certain to always return true).</p>
+ <p>
+ Minor fix in dead code</p>
+ <p>
+ Fix infinite loop in dataflow</p>
+ <p>
+ Update r9c/{inets,mnesia} results in dialyzer's test
+ suite</p>
+ <p>
+ Add origin information to #fun_var closures</p>
+ <p>
+ (Thanks to Tuncer Ayaz and Maria Christakis)</p>
+ <p>
+ Own Id: OTP-9529</p>
+ </item>
+ <item>
+ <p>
+ Quote atoms if necessary in types</p>
+ <p>
+ Atoms in some occurrences were not correctly quoted when
+ formatted to strings, for instance by the typer program
+ (Thanks to Tomas Abrahamsson)</p>
+ <p>
+ Update Dialyzer's reference results</p>
+ <p>
+ Own Id: OTP-9560</p>
+ </item>
+ <item>
+ <p>
+ Fix typer's crash for nonexisting files Remove unused
+ macro Fix bug in dataflow Decrease tuple arity limit This
+ fixes a memory related crash.</p>

+
+ <section><title>Improvements and New Features</title>
+ <list>
+ <item>
+ <p>
+ Types for several BIFs have been extended/corrected. Also
+ the types for types for <c>lists:keyfind/3</c>,
+ <c>lists:keysearch/3</c>, and <c>lists:keyemember/3</c>
+ have been corrected. The incorrect/incomplete types could
+ cause false dialyzer warnings.</p>
