Published under a CC-BY-4.0 licence % Please email me (alastair.kay@rhul.ac.uk) with any bug reports or feature requests. % If you find this library useful, please cite its usage in your work, using arXiv:1809.03842, and possibly the DOI: 10.17637/rh.7000520. % Usage is at your own risk. +%version 0.9.6: +% changed packaging so there isn't a compile warning any more +% modified the meter command so that \meter[draw=blue]{} colours everything blue, not just outline. +% added trash command +% added \ctrlbundle command so that \ctrl works well with \qwbundle[alternate]. If you supple \ctrlbundle[2]{}, then the bundle only contains 2 wires instead of the default of 3 +% \qwbundle[alternate] now also works with the parameter \qwbundle[alternate=2] to only have 2 wires in the bundle. +% added \midstick. Works a bit like rstick and lstick, but reserves space for the text. Can choose to have brackets=none|left|right|both (default is both). Gives better method for circuit identities and other things. +% added "align equals at" key for setting circuit identities (specifies wire number that should line up with equals. can be non-integer) +% added makeebit command. accepts one parameter which is the text. Haven't got tyling and different angles of the split working yet. +% added bundle option to supplement nwires and cwires. +% fixed bug where you couldn't put a wire command after the declaration of a multi-qubit gate command. %version 0.9.5: % fixed bug which meant multi-wire gates didn't work outside of an environment such as center. %version 0.9.4: @@ -32,13 +43,13 @@ %version 0.9.0: %original
