Lmod 8.4+
   (8.4.1)  * Issue #460: Change meta modules from having a separate file= to be
              a fileT= in ModuleA
   (8.4.2)  * Actually set shell name from the command line and not based on Shell Object.
            * Issue #462: Allow for more matches with extended default.  The last character can
              be: . _ - + = or letters
   (8.4.3)  * Adding userInGroups(group1,group2,...) as a replacement for userInGroup(group)
              (userInGroup calls userInGroups)
            * Added new command check_module_tree_syntax to check for multiple marked defaults
              for the same shortName module and that all modulefiles pass the syntax test.              
   (8.4.4)  * Fix bug in MasterControl:userInGroups(): capture returns string and status and
              tonumber() doesn't like it.
   (8.4.5)  * Issue #447: Report (N/A) when global alias does not resolve with current $MODULEPATH
   (8.4.6)  * Modify spiderT to know about mpath dependent aliases, hidden modulefiles.
            * Issue #467:  added MName:find_exact_match_meta_module() to handle hidden meta modules
	      loading. Changed versionStr (user input) to be false and not nil   
   (8.4.7)  * Issue #461: Modified instructions for installing lua and lua-posix on ubuntu 18.04 and 20.04
            * Issue #469: Use LMOD_ALLOW_ROOT_USE to control whether root uses Lmod or not
	    * Suggestion from Xavier Delaruelle to define ModuleTool and ModuleToolVersion env vars
	      and versioncmp test.
            * Updated documentation for Lmod Env. Vars and TCL module functions.
   (8.4.8)  * To match Tmod, ModuleTool and ModuleToolVersion are also TCL global variables.
   (8.4.9)  * Issue #470, Issue #471: fix fish logic w.r.t. LMOD_ALLOW_ROOT_USE
   (8.4.10) * User found bug where if sha1sum was not in current path, "module save" would die.
            * Issue #474: Updated FAQ doc on how to handle missing new modules.
   (8.4.11) * Issue #476: Move mrcT.mpath to separate table mrcMpathT
            * Issue #477: Support finding real modules names with a version called "default"
	    * Show extensions from hidden modules when doing (module --show_hidden avail)
	    * Add option (--nx, --no_extensions) to not print extensions when doing "ml avail".
   (8.4.12) * Make --nx only remove extensions from ml avail not spider. Make it a configure option.
   (8.4.13) * Issue #479: Reworked MRC to fill mrcMpathT with mrc entries for each directory in
              $MODULEPATH. Then walk each mpath directory for hidden, global aliases, and module aliases
   (8.4.14) * Issue #480: make "module try-add <module_name>" ignore failure to be found but report
              broken modules.
   (8.4.15) * Issue #480: Fix the try_load() function to ignore failure to be found but report
              broken modules.
   (8.4.16) * Issue #483: Added hidden file to spider tests.  Showing that it works correctly.
            * Fixed bug where providedByT (a.k.a. Extensions) was always printed when doing "ml keyword ..."
	    * added lua module function requireFullName()
   (8.4.17) * If python exists on system use $PYTHON -mjson.tool on the generation of *.json files from
              update_lmod_system_spider_cache_files script.  Note $PYTHON is found by looking for
	      python3, python or python2
	    * added TCL module function require-fullname to match requireFullName in Lua.
            * Do not check $cache_type twice, use $ext = lua for lua like operations in update
              spider cache script.
   (8.4.18) * Issue #481 (and PR #488) are merged in.
              New configure options to specify where lua and luac executables exist
              (--with-lua= and --with-luac=).  It is also possible to use --with-luaSuffix=.
              Both --with-lua= and --with-luac= must be specified if one is specified
              The option --with-luaSuffix= can not be used with --with-lua or --with-luac
            * PR #489 is merged in. This fixes bug with "module --terse keyword"
   (8.4.19) * MasterControl:unsetenv(name) also clears stack if it exists.
            * Issue #490: use old way of following readlink as "readlink -f" is not universal.
   (8.4.20) * Adding wV field to MName and MT class (Merged wV branch)
            * This allows users to tell how (if any) default is set.

   (8.4.22) * Issue #496: Fix luaCmd -> luaprog.
   (8.4.23) * Issue #496: Fix goto in luaterm pkg.
   (8.4.24) * Issue #497: Need to quote '?' in csh.
            * Make list of modules from spider skip .version* and .modulerc*
	    * analyzeLmodDB now takes a list of all modules so that zero module usage can be reported.
