CTAN release v1.3.2 (2023-07-27)

This is the same as v1.3.1, but the documentation has been updated (basically, better style for the code example).

CTAN releaase 1.3.1 (2021-06-16)

Minor bug fix:

Added the xcolor dependency thanks to @Ri0016.

Notice that if somewhere your projects loads catoptions you can experiment errors --- don't load it.

Release v1.3 2020/01/12

• Minor fixes to the manual; added a warning in case the patching of picture.sty fails.

Release v1.2 2020/01/08

• Added optional argument to the commands and make them sensitive to math mode (thanks to @tallmarmot for the suggestion and example code).
• Added fill color for the circles' background (thanks to @EGreg on TeX.stackexchange.com)
• Fixed several bugs.

Release v1.1 2019/11/01

This is to have a more "serious" look by default, see issue #1 on GitHub. The legacy package option will allow reverting back to the legacy (one week ago!) behavior.

The default reference text for \ref commands has been changed to the plain number.

Also, added a "none" pseudo color that is not issuing any color-changing command.

Thanks to Christophe BAL for the suggestion.

First CTAN release

This is the first release of the package that will be submitted to CTAN shortly.
