By now everyone knows that no big features except those in the exception list (see couple of posts up) will be integrated. This means that this thread will wither. That’s of course good news: it means that the release is closer. But meanwhile I found one feature worth mentioning. (I have seen a mention of it somewhere else, too.)
Jean-Pierre Charras, the founding father of KiCad, has some connections to Ucamco, the company which governs the Gerber format standard. Ucamco has announced a proposal for X3 for including assembly data in Gerber data and it has been included in the standard. You can see JP’s name in the documents.
You can also find files created with KiCad as an example. How was that done?
KiCad is ahead of time, possibly the first or at least among the first codebases implementing X3.
