• fixed: falsely hiding some missing information (split merged sets with nodump chds)

• fixed: www profiler, don't truncate protocol from page url, so you can use http or https (however you need to update your settings once)
• fixed: www profiler shows downloaded and updated dats still as update
• fixed: don't prompt user that the download was ok when www profiler loaded a decompressed dat
• fixed: downloaded and not moved decompressed dats get removed when closing cmpro
• fixed: some sets don't get marked as unneeded or weird renames are proposed in mame/software list combined mode only
• fixed: parent/clone relationship of software list roms got lost under some circumstance
• fixed: 32k pathlength support doesn't work for profiles/datfiles
• fixed: fixing a wrong sysdefpath issue only worked when you got "ask before fixing" enabled

• added: zip property tab in Settings-Compressor with e.g. zip compression level setting option
• misc: use a private use utf8 char for internal set subfolder handling, so all kind of apostrophes '´` in rom/setnames are allowed again and won't be replaced

• misc: updated rar dll
• fixed: some zip circular rename operations could kill files
• fixed: some zip renames could create dupes (4.038a) (MAME .223 v4mdice v4monte issue)

• misc: dir2dat writes chd files as disk
• misc: added cmpro.ini option Adv_WindowToFront = on (on / off) to handle the automatic bring window to front functionality

• misc: remove possible empty setfolder when a chdfile is moved
• misc: cmpro.ini setting Adv_AvoidPCSleep=on can be used to avoid PC switching to hibernate/sleep mode during scan/merge/rebuild/dir2dat operations (default = on, i.e. it won't switch)
• misc: updated to rar 5.50

• fixed: dir2dat creates subfolders for found filenames with `. Now it translates it to ' (as the parser does anyway)
• fixed: unique softwarelist folder check can fail and only show an empty list instead of details
• fixed: batcher's "for rompath naming use "dafilefolder" created double foldernames when using dats with subfolders

• fixed: statistic count values for sets which do not really exist (e.g. sets with only biosroms and nodumps/samples)
• fixed: fix test for unneeded rom/detecting not separated biosrom checks interfear and you need a 2nd scan to get rid of it (MAME .178 decoccass v0a-.7e issue)

• fixed: rebuilder matched files counter

• fixed: various softwarelist/standard mix problems with double set names - chd name matching problem which came back with 4.030 fix for unneeded chds - identifying wrong set leading to all kind of sideeffects like prompts to rename sets or skipping wrong placed sets - skipping detection of a missing set when identical sets are shared in different sysdefpaths - reporting wrong "wrong sysdefpath" warnings when 100% identical sets are shared in sysdefpaths or for clones where parent's set name was identical in different sysdefpaths or when a set was renamed and old name is now used in a different sysdefpath

• fixed: general 32bit cut down issue when calculating size/checksums of files in zip64 archives
• misc: xml datfiles with "machine" elements instead of game elements are parsed, too
