Broken build and missing Webix versions from

I’m a Pro user and I ran into two problems with Webix 6.3.2:

A. Running the custom build works, but the minified build fails:

$ npm run build --config-mode min

> webix@6.3.2 build /download/prg/Webix632
> rollup -c ./rollup.config.js "min"


min → codebase/webix.js...
[!] Error: Could not resolve entry (min)

$ node -v
v12.2.0
$ npm -v
6.9.0

B. Trying to debug what broke, I wanted to download the last known working version, 6.1.5. Problem is, I can’t find in the clients area. Other versions are missing too, e.g. 6.2:

UPDATE: I get the same minified broken build error with Webix 6.1.4 and Node v11.15.0, so I suspect there’s a dependency change that broke it.
