With this PR, Renovate will default to raising only one major PR at a time. e.g. if you have Webpack 1.x then you will get only one major PR for webpack v3 and not also for v2. set multipleMajorPrs=true to get multiple.
Closes#1101
Before, if current node version was 7 then Renovate would propose upgrades to versions 8 and 9. However, like with npm we should allow upgrades to unstable only if it’s the same major version or if ignoreUnstable is explicitly set to false.
This adds a configuration option unstablePattern - used only by Docker currently - that can be used to define a regex patternt to identify “unstable” versions.
Closes#1035
This PR adds support for 'AS' names in Dockerfiles. e.g. `FROM node:8 AS base`. It also adds logic to detect and ignore - for now - any image sources from custom registries.
