Detect npmrc in root of repo and make sure it’s set early. Also ensure npmrc is reset at start of each run if necessary.

Helps #1335

Adds new configuration option “pathRules”. pathRules is an array of path rules. Each rule should contain a “paths” array which uses string or glob matching like the existing ignorePaths. If any of the paths in a rule matches a packageFile then the remaining configuration from the rule is applied to the packageFile.

If branch automerge *previously* failed, then still make sure we are keeping the PR up to date.

Closes #1336

Previously, Renovate would attempt to keep a branch up to date even if users had edited it. e.g. adding commits on top of the existing branch if newer versions were released. Now, Renovate adds a warning comment if a user has edited a branch, making it clear that responsibility for the branch is over to them and how they can undo this.

Closes #653

Deduplicate changelogs in monorepo PRs. i.e. the same monorepo won’t be included more than once.

This reverts commit eb579ff3.

For some reason it seems to be causing a reduction in throughput per hour in the app once deployed.

When 404 or 422 errors are encountered writing updates, Renovate will now restart in an attempt to fix it. Usually this is because branches/PRs have been edited or closed while Renovate is running.

Closes #1299

Closes #1246

This PR adds new checks that:
- Website configuration options are listed in alphabetical order
- Every relevant configuration option in source code is documented on the website
Website docs have been updated accordingly to pass.

Closes #543, Closes #1310

This PR adds the configuration option “commitMessageBody”. The contents of this will be appended to the commitMessage, separated by two line returns.

Detect if the upgraded dependency was already in “resolutions” and update it too if it was an exact match. Warn if it was not.

Closes #1318

Closes #1334

Closes #1311

Now, if every upgrade in a group has the same new version, then the PR title will include this version.

Closes #1332
