Continuing the discussion from Idea: Eeschema Multiple Alternate Symbol Shapes because that thread has been closed.
Hover over the pencil 🖉 on the top right to see the date of the last update (click for history).
The symbols (only) can also be installed on KiCad 6 with Tools → Plugin and Content Manager (PCM). To add the library after installing, use Preferences → Manage Symbol Libraries… followed by Add empty row to table (the
+ icon) with the Library Path given in the content description.
The libraries and demos are as well in the repository for local installation using Tools → Plugin and Content Manager → Install from File…. The zip files with demo in their name are example projects (use File → Unarchive Project… instead of PCM). Version 0.5.2 are KiCad 5 libraries (that can also be used and migrated in KiCad 6), version 0.6.2 are KiCad 6 libraries. Currently, the symbols are identical except for some arc adjustments (and corresponding config files).
Elektuur (now Elektor) style symbols introduced in the later 1970s (until the early 1990s when they became more angular). The symbol size has been increased by 1.6% (2 mm grid to 80 mil grid) and the pins realigned to a 100 mil grid.
Generic symbol library (UJT, BJT, JFET, MOSFET, C, D, LED, LDR, Schottky D, Zener D, varicap D, L, P, R, NTC/PTC R, VDR, Re, S, La, LS, Mic, GND, Xtal, F, battery, meter, terminal, jumper, heatsink, opamp, inverter, AND/NAND/OR/NOR/XOR/XNOR, NOT, SCR, triac, plug/socket, TP, arrow):
