+
+From v. 4.55 to 4.55a
+  Add option that latexmk returns a non-zero status code when
+    the final run of (pdf)latex gives warnings about undefined
+    references or citations or about multiply defined references.
+  Implement $warning_cmd to allow a visual cue for these situations in
+    pvc mode (in addition to the current possibilities for
+    $compiling_cmd, $success_cmd and $failure_cmd).
+
+From v. 4.55a to 4.56
+  Correct parsing of biber's log file.
+  Implement $warning_cmd.
+  Deal correctly with situation that files reported in the .fls file
+    as INPUT or OUTPUT files no longer exist at end of run. These
+    files aren't true source files or generated files from latexmk's
+    point of view.  Such cases can arise from a bug in the TeX
+    engine (as with lualatex in TeXLive 2016/2017).  They can also
+    arise when temporary files are created, read and deleted during
+    a run (as with the minted package).
+  Update example latexmrc file for pythontex.
+  Better error message when .bib file(s) not found.
+  Better handling and diagnostics when names of expected and actual
+    names of .log disagree.
+  In particular, there is some automatic reconfiguration when .log
+    file is not in expected place (e.g., because $aux_dir is different
+    to $out_dir, but TeXLive is used, so -aux-directory option for TeX
+    engines isn't supported).
+  Fix problem of .bib files sometimes not being found by bibtex when
+    latexmk runs under msys and -outputdirectory is specified.
+  Add use of environment variable LATEXMKRCSYS to specify system rc
+    file.
