The 1.13 release brings the new `qiskit` theme, built on top of Furo. The design aligns us with Carbon design requirements, has a more useful left side bar, and we went from 12,500 lines of CSS to 700 lines.
See https://github.com/Qiskit/qiskit_sphinx_theme#migrate-from-old-pytorch-theme-to-new-theme for migration instructions to the new theme. qiskit-sphinx-theme 2.0 will remove support for the old Pytorch theme, which we plan to release in July or August 2023.
We also made substantial infrastructure improvements, including adding [visual regression testing](https://playwright.dev/docs/test-snapshots). This will allow us to better maintain the quality of the theme and add future improvements.
