ZX-Poly v2.4.1 is released. It is a multi-CPU ZXSpectrum clone.

ZX-Poly changelog:
"Try use less resources" sleeps until the next frame instead of waking continuously, and steady borders use less CPU
keep full emulation speed when the window is not focused
demos no longer drop to half speed when a frame misses the 20 ms budget
Java Sound no longer inserts silence gaps between AY frames
opening the menu or pausing emulation silences the speaker again
the embedded JDK has been updated to 27+36
fixed the main menu not appearing on Linux with JDK 27, and changing Look & Feel no longer hides menu titles or crashes
updated input4j to 1.4.0
updated dependencies
fixed packaged start scripts (Linux single-instance lock, Windows JVM flags and working directory, macOS CLI arguments and numeric Info.plist version for SNAPSHOT zips, AppImage desktop entry)
fixed Linux speaker noise that stayed until the sound device was restarted, without adding delay between sound and action
fixed video timing so INT-synced border effects match real 48K, 128K and Pentagon machines and stay aligned with the paper
unused window space around the screen is filled with the current border color
fixed Low Pass Filter stereo balance and made the strength slider Mild–Strong
fixed undocumented XF/YF and WZ of repeating Z80 block instructions on the extra 5 T-states
WAV recording stays on after choosing a file until it is stopped manually
