Fixed: emailed sign-in links, a rare frozen dialog, and silent-by-default micro:bit audio
Three fixes from a teacher's bug report: magic links that work from any device, dialogs that never freeze the page, and micro:bit sound that requires a speaker, like the hardware.

A bigger engine: faster large circuits, fast Bode plots, SPICE import, nine new parts
The simulation engine gains a sparse solver and a true small-signal AC analysis, SPICE netlists import for free, nine device families join the catalog, and the engine itself goes open source.

A precision-instrument polish pass, and two Pro features go free
Menus with visible shortcuts, real dialogs everywhere, a decluttered scope toolbar, switches that toggle without hijacking your selection, and differential probes plus net renaming for everyone.

micro:bit compatibility fixes: display.clear, Snake, and steadier speed
Scripts that clear a looping scroll before drawing now behave like real hardware, and microcontroller circuits regain their adaptive speed.

Parts that heat up, wear out, and burn out like the real ones
Junction temperature, thermal shutdown, energy-based damage, real pull-up resistors on microcontrollers, honest floating-input warnings, and batteries that run down.

The scope stops lying: 10 kSa/s acquisition, measurements, and cursors
Acquisition moves inside the solver at up to 10 kSa/s, the scope gains Vpp, RMS, frequency, duty, and cursors, and every number now tells you how much to trust it.

Tilt it, ping it, breakout it: sensors and a redesigned Inspector
Interactive micro:bit sensor controls, a GPIO breakout, an HC-SR04 ultrasonic sensor, searchable palette keywords, and a rebuilt Inspector across every part.

Real MicroPython in the browser: BBC micro:bit V1 and an RP2040 board
Two MicroPython boards join the catalog. Write the same code your classroom uses, run it on a simulated board, and drive real breadboard circuits with it.

The oscilloscope learns to trigger, and nodes get names, colours, and labels
Triggered acquisition with persistence, scope channels mapped to circuit nodes, PNG waveform capture, on-canvas text labels, and a public embedded circuit you can poke.

Jumper wires, rail-less breadboards, and switches you can actually latch
Movable-end jumper wires, stackable rail-less boards, a 4-pin tactile button and a DPDT latching switch, plus freeform wire bending and a proper right-click menu.

Build circuits by keyboard: the canvas learns to talk to screen readers
The circuit canvas gains a screen-reader representation, keyboard navigation and wiring, precise part placement, and spoken announcements for what just happened.
