These packages were built with libjpeg-turbo 2.1.4:
https://sourceforge.net/projects/libjpeg-turbo/files/2.1.4/
and Adoptium OpenJDK 11.0.17_8:

Package signatures

To ensure the integrity of the TurboVNC binary packages, the RPM and DEB files and the source tarball are signed using the following key:
https://www.TurboVNC.org/key/VGL-GPG-KEY
https://keyserver.ubuntu.com/pks/lookup?op=get&search=0xae1a7ba4efff9a9987e1474c4baccab36e7fe9a1
and the Windows installers and Mac app/package/DMG are signed using a code signing certificate.

Packaging changes

• New RPMs with SHA-256 payload digests were uploaded on 2023-01-31. This fixes an issue whereby the RPM signatures could not be verified on Red Hat Enterprise Linux with FIPS mode enabled. The new RPM packages now require GLIBC 2.17 or later.

3.0.2

Significant changes relative to 3.0.1:

1. The Linux/Un*x TurboVNC Viewer now works around an issue whereby Java on Un*x platforms generates a key release event without a corresponding key press event for dead keys on international keyboards.

2. The TurboVNC Viewer no longer pops up the F8 menu if a modifier key (Shift, Ctrl, Alt, etc.) is pressed along with the menu key.

3. Hotkeys in the Windows TurboVNC Viewer can no longer be triggered using the RCtrl-LAlt-Shift modifier sequence, because Windows uses RCtrl-LAlt to represent AltGr on international keyboards.

4. The vncserver script now searches /usr/local/share/fonts for X11 fonts, which fixes an issue whereby the TurboVNC X server had few available fonts when running on recent FreeBSD releases.

5. The Windows TurboVNC Viewer no longer overrides Java's default choice of high DPI scaling algorithms (nearest-neighbor interpolation) when using integral display scaling factors such as 200%. The viewer now emulates the behavior of Windows, using bilinear interpolation with fractional display scaling factors (per 3.0[6]) and nearest-neighbor interpolation with integral display scaling factors. This improves the sharpness of text when using the Windows TurboVNC Viewer with integral display scaling factors. The turbovnc.scalingalg system property can be set to bicubic, bilinear, or nearestneighbor to override the TurboVNC Viewer's default algorithm choice.

6. The TurboVNC Server now handles multitouch events sent by the UltraVNC Viewer from touchscreen-equipped Windows clients.

7. The Mac TurboVNC Viewer no longer uses Command-V as a hotkey to toggle view-only mode. Mac applications typically use Command-V for pasting from the clipboard. Even though Un*x applications do not typically respond to that key sequence, Mac users sometimes attempt to use Command-V with TurboVNC out of habit, which caused view-only mode to be activated accidentally because of 3.0 beta1[28]. CTRL-ALT-SHIFT-V can still be used to toggle view-only mode.

8. The TurboVNC Viewer normally reserves CTRL-ALT-SHIFT-{arrow keys} as hotkeys to move the horizontal and vertical scrollbars. However, those key sequences are also used by Emacs and GNOME. Thus, the TurboVNC Viewer now sends those key sequences to the server if no scrollbars are visible or if keyboard grabbing is enabled.
