[greenkeeperio-bot]

🚨🔥⚠️ Action required: Switch to the new Greenkeeper now! 🚨🔥⚠️
This version of Greenkeper will be shutdown on May 31st.
With Integrations first-class bot support landed on GitHub and we’ve rewritten Greenkeeper to take full advantage of it. Simpler setup, fewer pull-requests, faster than ever.

Hello lovely humans,

eslint-plugin-jsx-a11y just published its new version 5.0.3.

State	Update :rocket:
Dependency	eslint-plugin-jsx-a11y
New version	5.0.3
Type	devDependency

This version is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of eslint-plugin-jsx-a11y. Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Do you have any ideas how I could improve these pull requests? Did I report anything you think isn’t right? Are you unsure about how things are supposed to work?

There is a collection of frequently asked questions and while I’m just a bot, there is a group of people who are happy to teach me new things. Let them know.

Good luck with your project :sparkles:

You rock!

:palm_tree:
