KiCAD example 4-layer, 0.8 thickness missing on github

I downloaded the example project files for the aisler boards, but it seems the version for the 4-layer ENIG board with 0.8mm thickness is missing.
I guess that is just an adjustment to the 3 dielectric layers, but I didn’t find any values for that in the design rules.

Hi :wave: we will update the templates soon when KiCad 9 is released in a few days.
There are some issues with importing KiCad 8 Templates into KiCad 9 thus it wouldn’t make sense to update the Templates in with the current version to re-do them in a few days.

Just to avoid misunderstanding, the new templates will still work with KiCAD8? (I usually try to keep my linux installation clean, which means KiCAD9 will not be running any time soon on my distribution).

Can you meanwhile provide the values for the 3 dielectric layers, so I can adjust my project manually?

KiCad files are unfortunately not really backwards compatible :confused: but since the majority of developers upgrades quickly we decided to only maintain our plugin and templates for the latest version.

You can find the Stackup in the design rule section: 0.8mm stackup

Can I ask which distro you are using? KiCad offers a PPA for Ubuntu and Flatpack images, which make it easy to update on Ubuntu derived distros.

I just went a bit back and forth between your design rules of the two 4-Layer stackups (sorry for overseeing those) and the KiCAD examples.
So only the core thickness is different for 0.8 and 1.6, that is easy to fix on KiCAD side.
I noticed one thing: the design rules for the 1.6 -4Layer board have a thickness of 1130µm, while the github examples gibe a 1.113mm thickness (which is 1113µm), might be worth checking before duplicating the new examples.
As for the distro I’m using, I’m a somewhat “old and stable evangelist”, so it’s Devuan stable (which is the no-systemd version of Debian). And from experience (~30 years linux user) I try to rely solely on the repos of the used Version whenever possible.
As long as the aisler plugin for KiCAD 8 will work for some while in the future and my adjustment of the core thickness will work of 0.8 boards, I’ll be fine.
Thanks for the excellent support btw.
