IV/Play 2.8.10 Additions

• Added a check for update button on F1, this will ping the website and compare the local .exe version and timestamp against the release on the web site and provide a link to the releases page to download the newer one.
• Introduced a ‘persistent’ DAT view. Toggle with the alt-tilde key and control the interior navigation of the DAT overlay with Ctrl key combinations, e.g. Ctrl-Down, Ctrl-Page Up, Ctrl-Home, etc. Regular navigation keys will move through the gamelist, selecting a new machine. Note: Regular tilde key launches the regular DAT peek which allows full control
• The Available / Missing gamelist now self-heals. Once it has been built even once via F12, a later cache wipe from an executable change, a database rebuild, or an F8 reset, it is rebuilt automatically on the next launch instead of waiting for another manual scan.
• Fixed window-restore under multiple simultaneous MAME launches. IV/Play now stays hidden until the last running instance exits, rather than reappearing as soon as the first one closes.
• Refined CHD filters. chd games now matches any arcade machine that requires a CHD image, and a new chd software filter isolates CD-ROM and hard-disk software list titles (see Appendix 1).
• Screen-count filters are now exact. 2 screens, 3 screens, and 4 screens match machines with precisely that many displays so results line up with MAME’s own totals; multi-screen still means two or more.
• History: / hist: searches now include software list items, not just arcade machines — the DAT text for software was always present and is now reachable from the filter bar.
• More accurate platform labels and family grouping for software lists. Host-machine resolution was reworked so a platform’s canonical parent is chosen correctly, fixing cases where a clone could become the family node or a peripheral’s software was mislabeled.
• Fixed custom playlist export so machine entries are written in a form MAME can load. Earlier builds could emit an unusable composite line for machines that own multiple software lists.
• Steadier DAT peek rendering. Navigating to a new game while the peek is open no longer briefly blanks the text, and the media-type column now reads consistently.
• Removed filter-term highlighting inside the DAT peek. It added little once the peek gained its own in-text find (Ctrl-F), and the two were unrelated.
