(Maybe because they want to open a project designed with this version of the lib.) And there is talk about giving users the option to get a small installer without libs. (Some users have data constrains. The installer is now nearly 1GB including all the 3d model libs.) It might also be a good idea to decouple the library release cycle from the software release cycle. I understand. We may want to explain that not to make users think they *need* to download them. I may submit a patch. - It says "Users who wish to keep their libraries up to date with the > latest additions should clone the library repositories using Git.".

(At least everytime it needs information about footprints for the first time in this session.) It does not even use git but pulls a zip archive. Another problem of having the github plugin is that the libs of the user get out of sync. So the symbol libs and 3d model libs stay at the version they where at the release of the installed software version. But the footprint libs get every change we make in the repos. (This means that if we rename a footprint, the footprint filters defined in the symbol might no longer work. Or if we change the scaling of the 3d model this will produce wrongly scaled results in the 3d viewer until the user manually downloads newer 3d models.) Because we decided to kill the one repo per footprint lib nonsense for the v5 release the current github plugin will no longer work there. (So you could say the download page is already prepared for the v5 release.) Unless of course someone fixes the github plugin such that it supports one large repo that holds all footprint libs. (But i would not suggest to use it as the default option, because it has the major drawbacks mentioned above.) Thanks, I understand it a bit better now. - I would explain the differences between schematic (old style, > per project) and layout libraries (new table style, per project or global). > Also in "Future of the Libraries" explain the new symbol table, etc. > If i read the conversations on the mailing list correctly then kicad 5 will include a symbol table for managing symbols. We could of course add a pointer to the documentation of this stuff.

Have a look at the other library related conversation here on the mailing list. https://lists.launchpad.net/kicad-developers/msg31312.html I think that's different from the landing download page, but not sure how both would interact. - If anything of what I said doesn't make sense or it's wrong, please let > me know.
