I wanted to mention that a new dev build 0.12.6dev6 is available, available via the usual means:
Possibly of interest, this dev build includes the recently merged PR for headless, programmatic PNG export. It would be extremely helpful if folks could test this out. There will also be a PR for SVG export merged next week. Both of these features rely on some new optional dependencies (e.g. Selenium). The docs are not merged or deployed yet but you can see the instruction for installing these dependencies and using the export function in the separate docs PR:
Besides testing this very long-standing feature, general testing and feedback would also be appreciated. We are targeting ~June 8 for a 0.12.6 release. There are a few regressions (currently being worked on) but the best way to find any others that are not known is for the community to put their eyes on things.
