   - `slice()` has no `dx` and `dy` parameters anymore. Instead, labels are handled through `label` exactly as in `gate()`. Also the `wires` parameter is replaced with `n` for consistency with other multi-qubit gates. 
   - Swap order of row and column parameters in `annotate()` to make it consistent with built-in Typst functions. 
 - Improvements: 
-  - Improve layout (allow row/column spacing and min lengths to be specified in em-lenghts).
+  - Improve layout (allow row/column spacing and min lengths to be specified in em-lengths).
   - Automatic bounds computation, even for labels. 
   - Improve meter (allow multi-qubit gate meters and respect global (per-circuit) gate padding).d
 - Fixes:

+When the circuit is laid out, the draw function is called with two (read-only) arguments: the gate itself and a dictionary that contains information about the circuit style and more. 
 
 Let us look at a little example for a custom gate that just shows the vertical lines of the box but not the horizontal ones.
