CHECKLIST

• I have read and followed the library conventions¹.
• For packages, I followed IPC7351C (see details in library conventions).
• For modified elements, I bumped their version number².
• I already used the new library elements in a design and verified their correctness (optional).
• I'm the copyright owner of the added content (i.e. the changes are made by myself, not copied/imported from somewhere else).
• I agree to publish all my changes under the CC0 Public Domain License³, allowing everyone to use and modify the content without any restrictions.

¹ Library Conventions: https://docs.librepcb.org/#libraryconventions
² Minor version bump if only metadata was modified (e.g. "0.1" -> "0.1.1"), major version bump if functional changes were made (e.g. "0.1" -> "0.2")
³ CC0 Public Domain License: https://en.wikipedia.org/wiki/CC0

@ubruhin PR updated!

The new symbol looks like this in LibrePCB though, the circles are hidden below the yellow rectangle:

Thanks for updating!

True, this will be fixed with the next release. And I just verified that the screw terminals look correct in the schematic editor of LibrePCB 1.0.0 - seems that only the symbol editor (and the "Add component"-dialog) is affected by the bug so I'd say it's fine to merge this PR without waiting for the fix.
