✨ New features

QIDI Box - QIDI printers such as the Q2 and Plus5 now get their own setup in the Client, with QIDI Box material mapping and QIDI's own error messages.
Bambu Lab H3C (experimental) - Connect the H3C and its nozzle rack, with chamber temperature, AMS switching and AMS drying from day one.
Anycubic Kobra 4 (experimental) - The Kobra 4 now connects. We built it without the printer, so tell us how it runs on yours.
Bambu Lab internal storage - Bambu Lab printers with built-in storage can print from it, so no SD card is needed. You can still choose the SD card in the printer's settings.
Keep the computer awake while printing - The Client stops the computer from going to sleep while a print runs, and lets it sleep again afterwards. It is on by default on Windows and macOS, and you can switch it in the settings.
Universal macOS installer - One installer for both Apple silicon and Intel Macs.

🚀 Improvements

A lighter, faster Client - Every printer brand now runs on one shared, rebuilt core. The Client uses less CPU per printer, which matters most on big farms and small computers.
Clearer setup help - An offline printer's card says why in its brand's terms, with one action to fix it. Bambu Lab LAN setup checks Developer mode first and shows what LAN-only mode gives and changes, side by side. A failed step shows its help right under the error.
Temporary computer notice - If the Client runs on a laptop that sleeps or switches off, it tells you why printers go offline and how to move the Client to an always-on computer.
Finds more printers - Discovery now searches every network adapter, so printers turn up on computers with several networks or a VPN.
Instant fan and light controls - A fan or light change shows right away instead of waiting for the printer's next report.
Uploads sized to your computer - The number of uploads at once now follows the computer's memory, and you can set it yourself in the settings.
Easier troubleshooting - Turn on debug logging from the settings, and a failed update now says why (no DNS, a timeout, an untrusted connection).
Safer sign-in settings - Changing the local sign-in password asks for it twice, so a typo can't lock you out.
Creality SPARKX i7 - Now in the list of supported models.

Fixed Creality K1, K1C, K1 Max, K1 SE and Ender-3 V3 KE refusing to start prints.
Fixed Creality printers refusing sliced 3MF files (error 2121), and connections dropping on firmware that ignores pings.
Fixed H2D-series prints pausing with "Failed to get AMS mapping table" when a filament was mapped to the external spool of a nozzle without an AMS.
Fixed Bambu Lab A-series printers showing a placeholder chamber temperature, and Developer mode not being detected.
Fixed Anycubic Kobra X finishes and ACE slot numbering, and a cancelled print blocking the next one.
Fixed Dremel printers not starting prints sent from SimplyPrint.
Fixed Flashforge AD5X uploads failing, reprints not starting, and unclear error states.
Fixed Duet print results being lost after a reconnect or reboot.
Fixed the Windows installer not allowing the Client through the firewall on domain-joined PCs. macOS now asks for Local Network access and says why.
Fixed the installer picking the wrong build on ARM computers with a 32-bit system.
Fixed an older update replacing a newer Client installed by hand on macOS.
