Preview Version: 1.99.45.23528 (x64)

Released: 12 January 2026

Everything done as part of preview build v1.99.44.23410

Added to the Appearance preference page an option to control if the OS text scaling might be used for effectively padding the skinned buttons to reduce their size

Changed the NotSoDirect preference handling to try to resolve a crash seen due to a weirdness with the install trying to access the OSes copy of dsound.dll
Changed how the Streaming Source plug-in works to resolve compatibility problems seen where the rate of the data that different v2 DNAS can consume from it
Changed how artwork changes (mainly for manually setting one for streams) are reported to better ensure skins will live update (mainly affects the x86 build)
Changed how the process's skinned scrollbar hooking is done in an attempt to try to resolve an on-going issue with it vs opening the preference window (this has mainly been affecting the x64 build but it's not consistent as most will never see this problem so this change may still not resolve this problem but it's a best attempt until I can somehow replicate it)
Changed the Win7Shell configuration to now only be updated if there's an actual change which avoids some possible weirdness previously seen with it's settings
Changed the MP3 length reading to default to off for the exact length checking option recently added as it causes too many slow down issues (now it's opt-in if bad files are experienced with more research needing to be done later on to try to find a better solution that hopefully doesn't require having to spin over the whole file when that's often not needed vs slow it down especially over network shares)
Changed the MP3 length reading related to the above action to try a few different ways to get a more likely to be valid length without parsing the whole file whilst avoiding the potential of a full scan
Changed some of the internal look-ups of the appropriate input plug-in to use to better leverage the cached handle if it relates to the playing item along with caching other requests to reduce some of the overhead when trying to get multiple metadata values from the files & other things during playback / selection changes (this is in addition to the other fixes noted below)
Changed how the post-release toast notification is setup when some of the needed aspects still need to be configured which is required for the OS to show the action buttons (the normal toast handling doesn't need this but having a prompt toast that is missing the buttons isn't the intent despite the OS having weird requirements to allow those buttons to be displayed)
Changed some of the core handling to reduce the calling impact of some of the methods along with a bit of de-duplication or removing additional aspects that aren't appropriate to the build type compiled

Fixed a regression from the prior 234xx builds causing the settings cache to incorrectly behave (this mainly affects the x86 build against modern skin handling)
Fixed a many year bug which could inconistently cause some of the settings files to not be loaded as expected into the settings cache which would cause things to revert to defaults &/or just act weirdly
Fixed some of the encoder plug-ins not always being able to be loaded due to the fun of dll dependencies (e.g. this caused enc_mp3 to not load in recent builds)
Fixed some further issues with the playback of Bandcamp related links which wouldn't behave as expected when pausing them though pausing a stream is just weird
Fixed a crash seen when doing a drag + drop action on the media library playlist views due to not releasing an internal lock before triggering the view update
Fixed a crash when trying to use the WMP playlist import action due to plug-in compilation issue which meant the wrong string was being used for the messagebox
Fixed the not equals string comparison with the NDE queries causing the results to not be as expected (e.g. this caused the exclusion of results to be weird)
Fixed higher than wanted memory usage & initialisation logic with the Streaming Source plug-in if it had been loaded but wasn't being actively used to stream
Fixed some artwork requests when playing streams not getting back the user customised artwork due to the direct data api not handling non-local path requests
Fixed the classic skin preview action on the Skins preference page not working due to a regression introduced some time back whilst adding better checking of cPro modern skins which broke the preview logic
Fixed the probable cause of a deadlock seen when trying to access the Podcast view in the media library if the configured feeds are already being updated
Fixed the next / previous actions being slow or appearing to cause the ui to lock-up for potentially half a minute depending on the skin &/or plug-ins enabled due to a message processing issue introduced by changes to try to avoid a hung ui / deadlock when updating the taskbar / main window text related to slow to respond files especially during start-up on non-local devices (this took a while to resolve)
Fixed the loading of the media library core not always being triggered as expected from the main ui thread which could cause it to not load at all or just appear as an incomplete media library window
Fixed tabbing within the Jump to Time & Jump to Track dialogs not working due to the fun that's getting such actions working within dialogs at times
Fixed some configuration reading issues seen when the settings cache is disabled & strings that should be read as unicode or utf-8 weren't always being processed into the expected form (if they weren't modified during that instance then there shouldn't have been any problems when starting with this build or by re-enabling the now fixed settings cache)
Fixed the JTF window position not always being saved if the window was open when WACUP is closed (closing the window manually before that was behaving)
Fixed a number of issues when configured to use the process volume to control the output especially when changing the default output device & it not synchronising the volume to match that device's output

Fixed the vu meter for the main window or modern skin visualisation modes not working consistently (23518 made this happen more consistently but it's been an issue for quite some time)
Fixed some regressions with the loading of the Streaming Source DSP encoder configuration plus adding extra checks to avoid invalid configurations being loaded along with prior problems when trying to generate multiple AAC streams due to how the different AAC encoders require being configured & some other small problems found which prevented the settings cache being applied to dsp_wc & the enc_*.dll

Other small changes as part of trying to determine why some of the on-going crashes are still happening or where it cannot be replicated but changes were made
