 - **Camera settings have their own tab, and the settings menu is sorted alphabetically** — Camera settings were split across two tabs: external cameras under General, and camera tokens and the Streaming Overlay builder under API Keys. A new **Camera** tab now holds all three: **External Cameras**, **Camera API Tokens** and **Streaming Overlay**. Old links to the tokens or the overlay builder, including `/camera-tokens`, open the Camera tab. API Keys keeps API keys, webhooks, Connected Apps and the API browser, and is no longer shown to a user who may see none of them; before, such a user only went there for their camera tokens, so an API Keys link now opens the Camera tab for them. Settings search finds the Streaming Overlay builder. The settings menu now lists **General** first and the other tabs alphabetically in the interface language. In Connected Apps, the **Add app** button no longer runs past the edge of the card on mid-sized screens, and the Brazilian Portuguese camera button on the printer card reads "Câmera" again instead of "âmera". Wiki updated. Covered by frontend tests.
 
 ### Fixed
+- **The log says which auto-archive switch skipped a print (#3477, reported by @Fuzzylog2x)** — Since 1.3.0 the global **Auto-archive prints** switch (Settings > General > Archive Settings) takes effect for prints started outside Bambuddy. Before, it was saved and never read, so an install upgraded with it off stopped archiving, and the statistics stopped updating. The log only said "auto_archive: False", the same as for a printer's own switch. It now names the global switch or the printer, whichever turned archiving off.
+- **A camera window no longer opens a dozen streams to the printer at once (#3431, reported by @buffdriver)** — When the floating camera window was open while the page loaded (after a refresh, for example), Bambuddy opened about twenty camera streams for it. Only one was shown. The browser kept the rest open until the tab was closed, and they filled its six connections to the server. The page started each stream while still preparing to draw the window. It prepared the window several times before showing it, and every attempt left a stream behind. Streams now start only once the window is on the page. The camera page, the camera wall and the stream overlay start their streams the same way.
+- **A printer whose file service hangs during a print is no longer asked again and again until it refuses every upload (#3474, reported by @F9mm)** — When the card could not be read at print start, the timelapse baseline was read again every two minutes for the whole print, and each round walked the card twice: up to eight new FTPS connections, each hanging for 30 s against a hung printer. An H2S kept a session for every one of them, then answered every connection with "421 There are too many connections", and no queued job could reach it until the printer was restarted. The card is now read once per round. It is read again only while the print records a timelapse, the wait doubles after each failed round (up to 30 minutes), and it stops after five. A connection or listing that times out now pauses the background timelapse scans of that printer for five minutes. Opening files and sending prints are not held up by this. A printer that answers "421 too many connections" now gets its own message in the queue, saying it may need a restart, instead of "Bambuddy will retry automatically". Wiki updated.
 - **Obico failure detection scores like Obico, and a resumed print isn't paused again (#3459, reported by @jasoncronje)** — Bambuddy's port of Obico's scoring left out the step that subtracts the long-term average, so whatever the camera always sees (plate texture, labels) added straight into the score, and the configured action ran as soon as that score passed High. The decision is now Obico's own: the score is the smoothed value minus the printer's long-term average, which carries over between prints on the same printer, so a background that is always in view no longer builds up. Between Low and High a slow build-up is not failing. **Notify only** fires at Obico's alert level, while **Pause print** and **Pause and cut power** wait for its pause level, which takes a clearly stronger signal and is now shown in the Status panel. A detection that appears suddenly and stays is still treated as a failure, as in Obico. Pausing a print no longer resets detection, so a print Bambuddy paused is not paused again after you resume it; the next print starts fresh. Wiki updated.
 - **A dropped printer connection no longer replays old commands and cancels the print (#3454, reported and diagnosed by @SaadShaya7)** — When the connection to a printer dropped and came back by itself, every command still waiting for the printer's acknowledgement was sent again. Bambu printers often don't acknowledge, so that could be a Stop or a print start from hours earlier: a print 4 hours in was cancelled seconds after the reconnect, and an old print start raised "Device is busy and cannot start new task". Commands from the previous connection are now dropped when it comes back, also when a printer that was switched off is turned on again, and the log says how many. A command sent in the seconds before a drop isn't sent again; click it once more.
 - **Finish photo: the plate is no longer driven to the bottom after a tall print** — With **Restore plate for finish photo** on, Bambuddy lowered the plate after the photo to the print's height + 100 mm, whatever the printer. On a 238 mm print on an H2C that is Z338, past the bottom of its travel: Bambu's own end G-code stops at the print's height + 2 mm when +100 doesn't fit, and the printer does not stop G-code sent over the network at its limits. The plate now goes back exactly where the print's end G-code left it, read from the archived file, and is only raised for the photo when the end G-code left it lower than just above the print (the H2C's doesn't, so its plate stays put). A file whose end position can't be read is not moved at all. Wiki updated.
