Changes in version 4.88:

• Some corrections to documentation, notably for $dvipdf and $dvips_pdf_switch.
• Improve some messages.
• Miscellaneous bug corrections.
• Use clock time for timing reports on cygwin and msys, and not just Windows.
• On Linux, default command for starting previewers is xdg-open.
• Add lualatex-related item to @file_not_found patterns.
• Add -cc (continuous compile) option, equivalent to -pvc -view=none.
• For msys, make better setting for @rc_system_files.
• Avoid unnecessary extra run(s) of lualatex after font cache is updated.
• On Windows, change default for $dvipdf so that -dvipdf works on Windows.
• Prevent loss of memory of state of custom dependencies that occured after a run of latex that ended early because of an error: When custom dependencies were applied to files generated during a run of latex, the memory loss would result in much excessive invocation of custom dependencies.
• Update nomenclature_latexmkrc.
• Prevent loss of memory of state of cus_deps and their uses after a run of *latex that gives an error. Previously, after a run is aborted early because of a syntax error (etc) and a second run is done after file(s) are corrected, sometimes the loss of memory would cause unnecessary (and sometimes very time consuming) extra runs of cus_deps.
• Correct statement of -bibtex* default in on-line help.
