+List of main changes in latexmk
+
+
+From v. 3.04 to v. 3.07
+ Pdf files can be made by any of three methods: pdflatex, from dvi
+ or from postscript.
+ Extra command-line options -- see documentation
+ Improved configuration options -- see documentation
+ Bug fixes, etc
+ Improved detection of dependencies
+ If latexmk exits because of an error with latex, bibtex
+ or makeindex, then it gives a non-zero exit code.
+ Under MS-Windows allow wildcards in filenames.
+
+From v. 3.07 to v. 4.01
+ Allow dvips, etc to put files in temporary location then move to
+ final location. This enables the problem to be avoided that
+ some viewers look for changes in a file and read a new file
+ before the writing of it is complete.
+ Ensure that an error in exectuing an rcfile results in an error
+ message visible to the user.
+ OS-specific initialization code now includes section for Mac OS-X.
+ Make code safe, as far as possible, for filenames containing
+ spaces.
+ Change method of detecting out-of-date-ness, etc, to examine all
+ files for changes. Keep a database (in a file with extension
+ fdb_latexmk) of the previous state of the files. The aux.bak
+ and idx.bak files are no longer used. The primary method of
+ detecting change is from the md5 checksum of a file. This deals
+ automatically with the vast majority of cases where there is
+ circular dependence of files, without needing special coding in
+ latexmk to know which input files to a LaTeX run are generated
+ from a previous run.
+ Hence make a much more systematic and general method for treating
+ dependencies.
+ Substituteable place holders allowed in command specifications, to
+ allow very general specification of commands (including multiple
+ commands, pipelines etc).
+ Extra option --dependents to list dependent files.
+ Support for multibib.sty, multind.sty, etc.
+ Support for index.sty as well as makeidx.sty.
+ Allow .latexmkrc as file name in project directory (as opposed to
+ latexmkrc).
+ Command-line option -e to allow execution of initialization code
+ from command-line invocation of latexmk.
+ Routines add_cus_dep, remove_cus_dep and show_cus_dep for
+ manipulating custom-dependency list.
+ Ability to specify lines to be ignored in computing md5 checksum of
+ a file of a particular extension. (An example would be a
+ comment line in an encapsulated postscript file that contains
+ the date and time it was created. Such lines may change without
+ having any consequence on the use of the file.)
+ Miscellaneous bug fixes, etc.
+ Improvements in parsing of log file
+
+From v. 4.01 to v. 4.05
+ Miscellaneous bug fixes
+ Fix bug that -ps -pdfps runs ps2pdf before dvips
+ Deal with quoted filenames in log file
+ Correct problem with invocation of MSWin start command
+ -c and -C now also delete fdb_latex file
+ For home directory (where user's .latexmkrc is located,
+ when $ENV{'HOME'} does not exist, use $ENV{USERPROFILE}
+ (suitable for MS-Win).
+ Correct treatment of -e option
+ Fix possibility that unwrapping of lines in log_file is done
+ incorrectly
+ Correct parsing of log file
+ Improve diagnostics of reasons for rerun of external program.
+ Fix problems when using both latex and pdflatex
+ Configurable extensions for finding cusdep
+ Change to a nicer #! line
+ Safer use of % in placeholders in commands
+
+From v. 4.05 to v. 4.07
+ In preview-continuous mode, arrange that ctrl/C used to stop the
+ processing loop does not automatically kill a script used to
+ call latexmk
+ Better handling of situation when a run of (pdf)latex does not
+ produce a dvi or pdf file, or when the opposite type of output
+ is produced than expected (e.g., pdf instead of dvi by latex)
+ Deal better with case that file is written and read by (pdf)latex
+ during a run
+
+From v. 4.07 to v. 4.10
+ Binmode for log file under MSWin to avoid problem with ctrl/Z
+ written by Miktex 2.7 giving spurious end-of-file.
+ Deal with issues in depedency structure caused by epstopdf, which
+ automatically creates pdf files from eps files during run of
+ pdflatex.
+ Correct problem with determining use of custom dependencies, when
+ file-not found-report has extensionless filename, but
+ corresponding .tex file exists.
+ Preview-continuous mode now doesn't bomb out if there are errors
+ during first run of (pdf)latex. (Previously that caused the
+ previewer not to run even if viewed file exists.)
+
+From v. 4.10 to v. 4.11
+ Corrects a long-standing bug that when the main file uses
+ bibtex, and uses \include for subdocuments, changes in
+ bibliography citations did not always trigger a rerun of bibtex.
+ Fixed a problem that latexmk did not detect changed aux files etc
+ on a small document when the run of (pdf)latex was within the
+ 1-second granularity of filetimes.
+ Improved start-up times on some large documents by avoiding
+ unnecessary recalculations of md5 checksums.
+ Deals better with eps-to-pdf conversions reported by epstopdf
+ package.
+ -silent option now causes suppression of certain messages about
+ non-existent files
+ When view files are make via a temporary file (not-yet-documented
+ feature), delete old view file before moving the temporary file.
+ (To avoid reported bug in kpdf and okular.)
+ Corrects a problem that with an error introduced at v. 4.08 that
+ on finding an error in processing one file latexmk exits rather
+ than continuing processing other requested files. The exit code
+ returned by latexmk was also incorrect in this situation
+
+From v. 4.11 to v. 4.12
+ Added an option not to run bibtex (to deal with situations
+ where a bbl file is available but not the bib file from which
+ it was made).
+ Corrected misprints in documentation.
+
+From v. 4.12 to v. 4.13
+ Corrected clean_up so aux file is deleted.
+ Default for running bibtex: Only when .bib file exists.
+ Correction insertion of bbl into list of generated extensions.
+
+From v. 4.13 to v. 4.13a
+ Corrected a problem that clean-up option (-C) failed to delete
+ certain generated files.
+
+From v. 4.13a to v. 4.15
+ Change defaults on $latex_silent_switch and $pdflatex_silent_switch
+ to make them always TeXLive compatible.
+ To avoid problems with apparent source files that are incorrectly
+ determined from the log file: (a) Make sure md5 calc doesn't
+ bomb out on directory. (b) In parsing log file: if apparent
+ dependent file is directory, remove it from list of dependent
+ files.
+ Better diagnostics at end of run with multiple files: list
+ applications of latex and pdflatex that failed.
+ Fixed problem that with -pvc when (pdf)latex failed, latexmk kept
+ doing dvips, dvipdf, etc.
+
+From v. 4.15 to v. 4.15b
+ Changed default location of system rc files for cygwin to include
+ both Unix-like and MSWindows paths.
+ Changed use of Digest module to use of Digest::MD5 module, to give
+ compatibility with the limited installation of perl shipped
+ with TeX Live.
+
+From v. 4.15b to v. 4.15c
+ Solved problem that occasionally latexmk failed to detect a
+ dependent file when it analyzed a .log file. (It incorrectly
+ treated some lines of length 79 as being wrapped.)
+
+From v. 4.15b to v. 4.16
+ Solved another problem with misparsed log files. Some versions of
+ pdflatex fail to preceed some warning messages by a new line.
+ Thus these warning messages sometimes appear to be part of a
+ filename.
+ Updated documentation to mention previously undocumented feature
+ about the use of temporary files in making ps and pdf files.
+
+From v. 4.16 to v. 4.16a
+ Sanity check on $sleep_time. (Negative times and times between 0
+ and 1 are replaced by 1.)
+ Corrected problem under preview-continuous mode that some
+ previewers would not see the changed file on an NFS file
+ system.
+
+From v. 4.16a to v. 4.17
+ Deal with bug about misparsing log file with non-space-containing
+ filename that is followed by a space and a message on same line.
+ Previously, the filename would not be detected as a dependent.
+ With $force_mode on, do a better job of completing processing.
+ Remove long-unused options -F and -F-
+
+From v. 4.17 to v. 4.18
+ Only produce "Removing no-longer-needed dependent" messages
+ when diagnostics are on.
+ In analysis of log file, add test for natbib's citation-undefined
+ warning.
+ Correct misprint in documentation.
+
+From v. 4.18 to v. 4.20
+ Fix problem that when bibtex finds no citations, this is treated
+ by bibtex as an error. Previously latexmk respected this and
+ did not continue processing. Now if the only bibtex error is
+ the finding of no citations, then latexmk now treats it as
+ only a warning and continues processing (by latex/pdflatex) as
+ appropriate.
+ Get .bst file in source file list for bibtex. (So an update to
+ the bst file provokes a rerun of the relevant programs.)
+ Allow clean-up to delete destination files of custom-dependencies
+ Configuration variable $cleanup_includes_cusdep_generated to
+ configure whether this is done. (Default is off, for backward
+ compatibility.)
+ Remove use of --width option on $pscmd on linux. It's no longer
+ needed.
+ Remove double quotes (if any) surrounding output filename read
+ from .log file, to avoid wrong diagnostic message.
+ Allow a more general pattern for files to clean up (when the -c,
+ or -C option is used). For details, see the explanation of
+ the $clean_ext variable in the latexmk documentation.
+ Options to set commands used for latex and pdflatex, as in
+ -latex=special_latex_replacement_command
+ -pdflatex=special_pdflatex_replacement_command
+ (This is not yet documented.)
+
+From v. 4.20 to v. 4.21
+ Fix some problems with parsing quoted filenames in log file.
+ These prevented latexmk working correctly with latest version
+ of asymptote.sty.
+ Corrected potential bug in locating graphics files.
+
+From v. 4.21 to v. 4.22
+ Support use of biber (with the biblatex package) for generating
+ bibliographies, with automatic selection of bibtex or biber.
+
+From v. 4.22 to v. 4.22b
+ Compatibility with biber 0.7.2. (Latexmk failed to detect .bib
+ files used by biber 0.7.2.)
+
+From v. 4.22b to v. 4.22c
+ Biber support is now compatible with MikTeX.
+
+From v. 4.22c to v. 4.22d
+ Fix compatibility problem MiKTeX v. 2.8, that latexmk didn't
+ always detect use of makeindex.
+
+From v. 4.22d to v. 4.22e
+ Fix incorrect error handling in reading initialization files.
+ (Sometimes an error was incorrectly detected, after which latexmk
+ stopped.)
+
+From v. 4.22e to v. 4.23
+ Deal with problem that if maximum number of runs of (pdf)latex is
+ exceeded, -pvc mode infinitely repeats (pdf)latex
+ Fix problem that changes in generated files during run of
+ (pdf)latex may not be detected if the run is shorter than the
+ granularity of file times.
+ Corrections of comments and messages. Documentation improvement.
+ Correctly parse blg files of biber 0.8
+ Correct handling of errors given by rc files
+ Enhancements for convenient use of latexmk with Makefiles (options
+ -deps, -deps-out, -use-make)
+ -recorder option for improved detection of input and output files.
+
+From v. 4.23 to v. 4.23a
+ Correct bug in detection of source files listed in .fls file
+
+From v. 4.23a to v. 4.24
+ When running biber, find locations of source files when they
+ aren't in the current directory (by use of kpsewhich). This was
+ previously done for bibtex but not biber.
+
+From v. 4.24 to v. 4.25
+ Fix to evade apparent cygwin bug that prevented system
+ rc-file from being read.
+ Diagnostic for unreadable rc-file.
+ Add deps output file to target part of dependency information
+
+From v. 4.25 to v. 4.26
+ Make compatible with biber 0.9.4.
+ Fix some bugs in error reporting.
+
+From v. 4.26 to v. 4.27a
+ Deal with problem that making of ps or pdf file via a temporary
+ file fails if the command making it has no %D placeholder
+ Add png to list of graphics extensions for pdflatex
+ Add -norc option that prevents auto reading of rc files.
+ Options -aux-directory -output-directory like those of (pdf)latex,
+ to set the output directories of (pdf)latex. (-aux-directory
+ is MiKTeX only). Corresponding configuration variables, and
+ placeholders for command specification.
+
+From v. 4.27a to 4.28
+ Correct handling of situations where some file(s) needed by bibtex
+ (or biber) don't exist. Previously latexmk incorrectly stopped
+ with an error message instead of continuing.
+
+From v. 4.28 to 4.28a
+ Correct duplicate making of view file
+
+From v. 4.28a to 4.28c
+ When biber doesn't find the bib file, latexmk treats this as a
+ warning rather than a fatal error, so further processing
+ can continue normally.
+ Latexmk now parses correctly error messages from biber v. 0.9.7.
+
+From v. 4.28c to 4.29a
+ Latexmk now works with the feynmp package and mpost,
+ provided a suitable custom dependency is defined. (See the
+ example latexmkrc fragment mpost_latexmkrc in the
+ example_rcfiles directory in the latexmk distribution.)
+ If output directory is set, arrange that dvips can find files
+ there.
+ In searching for cus-deps that can make a missing file, look in
+ $out_dir.
+ Solves problem that sometimes dvips and dvipdf weren't run when
+ they should have been. (The problem only arose with certain
+ changes in eps files being made within a minute of the previous
+ run.)
+
+From v. 4.29a to 4.30a
+ Fix use of bibtex so that it works correctly when $aux_dir and/or
+ $out_dir are set.
+ Use OS-dependent search path separator when when manipulating
+ TEXINPUTS, etc. Then use of -output-directory and
+ -aux-directory options should work on MSWin systems.
+ Documentation of $search_path_separator variable.
+
+From v. 4.30a to 4.31
+ Add -M -MP and -MF options, like gcc.
+ Recorder option is now on by default.
+ Add options reproducing most options of (pdf)latex (list from both
+ TeXLive and MikTeX versions).
+ Options NOT implemented by latexmk at all:
+ -ini and -initialize since they refer to operations
+ not supported by latexmk
+ -includedirectory=dir its support needs extra code in
+ latexmk, not currently written
+ Options differently processed by latexmk:
+ -help
+ -version
+ -quiet
+ Options that are passed to (pdf)latex but that also have special
+ processing by latexmk
+ -aux-directory=dir
+ -output-directory=dir
+ -recorder
+ Add -latexoption=... option to latexmk
+ Add -xelatex option for use of xelatex
+ Change OS-X default for pdf previewer command to open
+ Command specification string can start with "include routine" to
+ invoke a Perl subroutine instead of an external cmd.
+ Viewers are detached by default. (The start keyword is now normally
+ superfluous in command specifications.)
+ Keyword nostart added in command specification.
+ Add configuration variables $compiling_cmd, $success_cmd,
+ $failure_cmd. These specify external commands (if any) to be
+ executed during latexmk's continuous preview mode at the
+ following points: $compiling_cmd at the start of compilation,
+ $success_cmd at the end of a successful compilation, and
+ $failure_cmd at the end of an unsuccessful compilation. They
+ can be used, for example, to show the progress of compilation by
+ setting the titles of editor and/or previewer windows.
+ If aux and/or output directories are specified but don't exist,
+ make them.
+ Remove excessive repetition of tests for changes of source files
+ (improves performance of latexmk in some situations).
+ Documentation improvements.
+ Minor bug corrections.
+
+From v. 4.31 to 4.33a
+ Improve operation under MSWindows: substitute "\" for "/" for
+ directory separator in command lines, deal consistently with
+ directory separator, which can be both "\" and "/".
+ Correct some bugs that interfered with use of auxiliary directory
+ and output directory for files generated by (pdf)latex,
+ especially with MiKTeX.
+ Fix problems caused because in the log and fls files MiKTeX writes
+ absolute path for many filenames at and below current directory,
+ and is inconsistent in its use of "/" vs. "\" as directory
+ separator.
+ Add $dvipdf_silent_switch configuration variable.
+ Improve handling of errors in (pdf)latex; previously latexmk would
+ give up processing in some situations continuing is correct.
+ Documentation corrections/improvements.
+ Reduce number of warnings in silent operation.
+ Cure slowness of v. 4.33 under Cygwin.
+
+From v. 4.33a to 4.33b
+ Documentation improvements.
+ Improve text displayed by using -showextraoptions option.
+
+From v. 4.33b to 4.33c
+ Correct infinite loop when maximum passes through latex/pdflatex
+ are exceeded
+
+From v. 4.33c to 4.34
+ Correct non-optimality that if (pdf)latex reads a file only after
+ it has been written in the same run, the file is not a true
+ source file, but nevertheless latexmk treats it as a source
+ file. Thus changes in the file sometimes caused latexmk to make
+ unnecessary (but otherwise innocuous) extra runs of (pdflatex).
+
+From v. 4.34 to 4.35
+ Correct bug in parsing fls file from native MS-Windows LaTeX (e.g.,
+ MiKTeX) when latexmk is run under cygwin. (The names of some
+ files used by latexmk incorrectly contained a CR character.)
+ Correct bug that when the --gg option is used, the rule database
+ from the old fdb file was used instead of being cleared.
+
+From v. 4.35 to 4.37
+ Correct failure that happens when name of current directory
+ contains characters with special meaning in regular expression.
+ -rules option now works with -pvc
+ Add -lualatex option, like -xelatex.
+ File specifications in $clean_ext and $clean_full_ext are allowed
+ to contain wildcards.
+ Warnings are given when rc file is a directory instead of a file.
+ Correct bug that if revtex4-1.cls is used, footnotes are set to
+ be in the bibliography, and latexmk's aux_dir or out_dir is set,
+ then latexmk fails to run bibtex when needed, because the
+ relevant bib file is not found.
+ Other minor corrections and code improvements.
+ Documentation updates and corrections.
+
+From v. 4.37 to 4.39
+ Automatic creation of necessary subdirectories of auxdir when needed
+ for writing aux files.
+ Add error diagnostics to if_source
+ Allow $print_type = 'auto', and make this the default, so that
+ when the -p option to latexmk is used to print the file, the
+ default is to determine the type of file to be printed, rather
+ than always requiring postscript.
+ Fix the failures when dealing with directories whose names contained
+ certain special characters in them (notably '[', ']' and space).
+ [Technical issue: these characters had special meaning when
+ previously interpreted as metacharacters in a glob operation.]
+ This gives dependency on Perl's File::Glob module, which is a
+ standard module in normal installations of Perl.
+ When an output directory is a subdirectory of a directory, ensure
+ that it is correctly created, if it has to be created.
+ Previously, the creation of the output directory when it does not
+ exist only worked for one level.
+ This gives dependency on Perl's File::Path module with v. >= 2.08,
+ which is a standard module in normal installations of Perl.
+ In output of dependencies, include pathname of target file(s) in the
+ rule.
+ In -pvc mode, writing of deps file (caused by the -M and related
+ options) is per make not per overall run.
+
+From v. 4.39 to 4.39 documentation update of 2 Dec 2013
+ Correct two errors in documentation and in the file COPYING.
+
+From v. 4.39 to 4.40
+ Fix failure to clean up correctly when root filename contains [,
+ which is a glob metacharacter.
+
+From v. 4.40 to 4.41
+ -c also deletes $deps_file if it is used
+ Quote jobname when needed.
+ Change maintainer's preferred e-mail
+ Attempt to improve handling of errors from (pdf)latex.
+ Fix up for the making of -eps-converted-to.pdf
+ Improve listing of warning lines from log file.
+ Fix failure when using both -cd and -output-directory
+ If user's home directory can't be determined, then don't read ~/.latexmkrc
+ Introduce configuration variable $silence_logfile_warnings
+ In setting $pscmd, allow for non-existent environment variable USER
+ Correct subroutine Run for internal cmd w/o arguments
+ Experimental: Add analysis hook for aux file.
+ System initialization files: allow them to be named latexmkrc as
+ well as LatexMk, for more consistency with user directory names.
+ Keep both cases, to preserve backward compatibility.
+ Change sign-on message. Bug report info with help.
+
+From v. 4.41 to 4.42
+ Fix bugs associated with the -cd option
+ Add missfont.log and the generated synctex.gz to standard cleaned-up files
+
+From v. 4.42 to 4.43a
+ Fix problem that source files are not correctly detected under
+ MiKTeX when name of current working directory contains non-ASCII
+ characters.
+ On cleanup, synctex.gz files are deleted only by -C, not by -c.
+
+From v. 4.43a to 4.43c
+ Correct normalization of filenames, so that initial "./" is always
+ removed. This prevents custom dependencies being run twice on the
+ same file.
+ Documentation correction on use of @BIBINPUTS.
+ Diagnostic correction.
+ Example rc file for using texinfo (thanks to Vincent Bela\"iche).
+ Additions to documentation concerning advanced configuration.
+
+From v. 4.43c to 4.44
+ Correct bug in use of %hash_calc_ignore_pattern
+ (Previously it only had its documented effect when a targetted
+ file hadn't changed in size.)
+ Correct error handling when biber finds a malformed .bcf file.
+
+From v. 4.44 to 4.45
+ Fix problem of -C not always working correctly when compilation was
+ with -pdf and clear was default.
+ Fix bug in limiting number of passes when $max_repeat >= 10
+ Fix bug in finding id of viewer process id under OS-X
+
+From v. 4.45 to 4.46
+ Correct creation of output and aux directories to correctly handle
+ relative paths when -cd is used.
+ Minor documentation corrections.
+
+From v. 4.46 to 4.48
+ Correct documention: default value of $recorder is 1
+ Add routines rdb_list_source, rdb_set_source for manipulating
+ dependency lists of a rule. Add these to the documentated
+ interface, in addition to the already documented rdb_ensure_file,
+ rdb_remove_files.
+ Update webpages in documentation.
+
+From v. 4.48 to 4.52
+ Optimize number of calls to kpsewhich. This often gives a
+ considerable savings of run time when a document includes many
+ graphics files that are in a texmf tree.
+ Fix bug that if an .aux file is deleted and latexmk is run, the
+ wrong number of runs of (pdf)latex was made.
+ Fix related problem that latexmk sometimes does too few runs of
+ (pdf)latex because of the incorrect detection that a file is only
+ read after being written.
+ Implement direct support for xelatex and lualatex. Previously these
+ programs were used by configuring the $pdflatex so that the desired
+ program is run instead of pdflatex. There are now configuration
+ variables $xelatex and $lualatex to specify the commands used, and
+ extra command line options -pdfxe and -pdflua.
+ In the case of xelatex, considerable improvement in run time is
+ given for documents containing large graphics files. This is
+ because compilation is made first to an xdv file instead of direct
+ to a pdf file. Only when this file is finalized is a single
+ conversion to a pdf file made. (This last step can be especially
+ time-consuming for documents that bring in large graphics files.)
+ Correct detection for missing graphics files with xelatex.
+ Work around LuaTeX line-wrapping bug.
+ Update documentation.
+ Minor improvements in code and diagnostics.
+
+From v. 4.52 to 4.52b
+ Fix bug introduced in 4.52 that use of bibtex wasn't always detected
+ when recorder mode is on.
+
+From v. 4.52b to 4.52c
+ Make -jobname work with -pdfxe and -pdflua.
+
+From v. 4.52c to 4.54
+ In deps_list, correct bug in identifying generated files.
+ Otherwise, generated files could have been identified as true
+ source files.
+ Remove insertion of name of deps file in list of targets in deps file.
+ Don't send to screen deps info in deps mode (unless diagnostics on).
+ Correct ordering of list of options given by -help.
+ Fix incorrect deletion of non-generated aux files.
+ Optimize away current directory string in $out_dir and $aux_dir.
+ Make compatible with future versions of Perl where File::Glob's glob
+ function won't exist.
+ Add extra value 1.5 for $bibtex_use, with corresponding option
+ -bibtex-cond1; this treats bbl files as conditionally precious in
+ cleanup operations, depending on the existence or non-exisitence
+ of bib files.
+ When running bibtex, ensure that the change in search paths is made to work
+ around deficiencies in bibtex is local and does not affect other
+ programs.
+ Collection of timing information now works in silent mode.
+ Set better default previewers for MSys.
+ Restore default of $analyze_input_log_always to 1.
+ This restores the default detection of certain constructs for dependencies
+ for input files in the .log file. See the comments on this variable in
+ latexmk.pl for details. This works around a problem caused by a change in
+ the behavior of lualatex in TeXLive 2017; it no longer lists all input
+ files in the .fls file. Note that latexmk.pl always examines the .log
+ file for relevant information. The variable $analyze_input_log_always
+ only concerns whether it looks for <...> and (...) constructs.
+ Add item to @file_not_found for the particular format of generic package
+ warning about "No file", that is produced by glossaries-extra, and
+ probably other packages.
+ Documentation improvements, especially on methods of implementing
+ custom dependencies for multiple kinds of index.
+ Document $kpsewhich_show variable.
+ Add a sample latexmkrc file for use with bib2gls and glossaries-extra.
+
+From v. 4.54 to 4.54c
+ Work-around for when bsd_glob is not available on old installations of
+ Perl. (Note that with these old installations, clean-up operations
+ may not work when file or directory names contain spaces.)
+
+From v. 4.54c to 4.55
+ Correct bug that $search_path_separator wasn't defined under msys.
+ Ensure that all configuration variables do have sensible default
+ definitions (which wasn't always the case previously).
+ Allow optional timeout in pvc mode after a period of inactivity.
+ (See documentation for -pvctimeout option.)
+ Compensate for problems caused by time offset between system time on
+ system running latexmk and file times on remote file system.
+ (It caused wrong behavior when a document uses biber, MiKTeX
+ is used, the aux_dir is on a remote file system, and the system
+ time on the host of the file system differs from the system time on
+ the system running latexmk.)
+
+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.
+
+From v. 4.56 to 4.57
+ Correct problem that in calculation of md5 checksum, an error
+ sometimes occurs about malformed utf8 characters. This can happen
+ if the environment variable PERL_UNICODE is set.
+ Add configuration variable $bibtex_fudge to allow to choose
+ whether to use the fudge that made bibtex run correctly when
+ an output directory (or aux directory) is specified. (A
+ planned future version of bibtex in TeXLive will not need
+ the fudge.)
+
+From v. 4.57 to 4.59
+ Deal with double quote ('"') characters in files on command line to
+ correspond to behavior of tex programs. Remove balanced pairs,
+ and give fatal error for unbalanced double quotes. (Note MiKTeX's
+ tex programs simply remove unbalanced quotes.) In all cases, the
+ '"' character is not allowed in a filename read by tex and
+ friends.
+ Give fatal error when name of tex file on command line is either not
+ allowed by tex and friends , or gives problematic behavior.
+ Use TEXINPUTS as search path for source files for custom
+ dependency.
+ Only give warning about differing expected and output filenames when
+ the extensions differ. All other cases gave only false positives.
+ Do better to ensure xelatex gets its -no-pdf option.
+
+From v. 4.59 to 4.61
+ Add -pdfxelatex and -pdflualatex options to set commands for
+ xelatex and lualatex (in analogy with -pdflatex and -latex).
+ Correct bug that use of -gg option with -deps-file option
+ did not create deps file.
+ After run of latex/pdflatex (etc), report count of warnings about missing
+ characters (typically unavailable Unicode characters). Messages about
+ this may appear only in the .log file and are therefore easily missed
+ by the user.
+ Fix problem that if biber gets a remote file, latexmk would report it
+ incorrectly as a missing file.
+ Provide routines for setting all of $latex, etc, with a common pattern.
+ Variables, options, placeholders for executing code in *latex before
+ inputting source file. The new variable is $pre_tex_code, the
+ options are -pretex, -usepretex, and the new placeholders are %P
+ and %U.
+ Improved definitions provided for the configuration of latexmk to
+ use pythontex; see the file pythontex-latexmkrc in the directory
+ example_rcfiles.
+ Correction to use of specifications in $clean_ext and
+ $clean_full_ext so that %R can appear in the interior of a string
+ as in 'pythontex-files-%R/*'.
+ Updates of documentation.
+
+From v. 4.61 to 4.63b
+ Update example_rcfiles/glossary_latexmkrc
+ Fix problem that in -cd mode, an error is raised when the path
+ part of the tex filename contains a character prohibited by *tex.
+ Implement changing of rule network when output of *latex is not what
+ is expected, e.g., because \pdfoutput is used in document.
+ Implement placeholder for true basename of main tex file, and use it
+ in jobname.
+ Various bug fixes.
+
+From v. 4.63b to 4.64
+ Fix problem that rules processing dvi and xdv did not always run after
+ rapid-fire changes in graphics files.
+
+From v. 4.64 to 4.64a
+ Fix incorrect listings by -rules and by -deps
+
+From v. 4.64a to 4.65
+ Fix incorrect parsing of long quoted filenames in log file that sometimes
+ prevented latexmk from running.
