• x86 32-bit (legacy) - requires Windows 7 or newer.
• x86 64-bit - requires Windows 7 64-bit or newer.
• 64-bit foobar2000 requires 64-bit builds of components; it can not load legacy 32-bit components. However, at this time, most components have 64-bit builds available already.
• ARM - requires Windows 11 ARM device.
• foobar2000 for ARM has been compiled in Emulation Compatible (ARM64EC) mode and can load components built for x86 64-bit. There's no need for component developers to specifically build ARM components.

User interface updates:

• Dark mode support on Windows 10 and 11. Add-on components need to be updated to utilize it.
• Added album art in Default User Interface playlist view.
• Clickable rating stars in Default User Interface playlist view (with new Playback Statistics component only).
• New Default UI element: ReFacets, reimplementing most of Facets functionality. Old Facets component doesn't work with new 64-bit foobar2000.
• Improved Default UI splitter, now allows any number of panes.
• Added 'remember per playlist layout' to Default User Interface playlist view.
• Added 'stream selector' element to Default User Interface toolbar.
• Some Default UI Elements (ReFacets, Equalizer, visualisations) now also accessible as Columns UI panels.
• Made more edit boxes recognize ctrl+backspace.
• Fixed remembered main window position/size not respecting system DPI settings.
• Configuration management changes:
• New internal playlist format, changes instantly saved to disk, no more recent changes lost on crash.
• New configuration data format, changes instantly saved to disk, no more recent changes lost on crash.
• For non-portable installs, profile folder is now %appdata%\foobar2000-v2. There is no need to back up old profile before upgrading, your foobar2000 v1.x profile will be left untouched.
• First run performs import of old configuration data (playlists, library).
• New full config reset semantics - now clears profile folder (optionally leaving user-components intact) instead of asking all components to reset themselves.

DSP technology updates:

• Made possible to apply DSP config changes without reinitializing affected DSPs.
• Allowed DSPs to manipulate their shown name depending on preset data.
• Added crossfeed DSP from foobar2000 mobile.
• Added sample rate exclusions to SSRC resampler.
