[greenkeeperio-bot]

Hello lovely humans,

react-redux just published its new version 5.0.0.

State	Update 🚀
Dependency	react-redux
New version	5.0.0
Type	dependency

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 react-redux.
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 ✨

You rock!

GitHub Release

This release is brought to you by contributions from the following people: @jimbolla, @vhmth, @btd, @roncohen, @ynonp, and @appden. In addition, there were many non-code contributions in discussions on issues and testing the alpha, beta, and rc versions by many other folks (too many to list!). Thank you to everyone who made this a very positive, inclusive, well-critiqued, community-driven release!

TL;DR

• Backwards compatible API
• Major internal changes
• Significant performance improvements in common usage patterns
• Bugs fixed
• Additional features added to connect()
• New connectAdvanced() API
• What's next?

API Compatibility

Version 5.0 maintains API compatibility with v4.x but due to major internal changes and potential behavior differences across nearly all API surfaces, semver dictates a major version bump. Also, it's good marketing! 💰 Store state change notifications sent to components are now guaranteed to occur top-down, so if your code may behave differently if it relied on notifications happening out of order.

Internal Changes

Internally, the code for connect has been rewritten from the ground-up to be more modular, with the intention of greater maintainability and extensibility. This has also led to some new features and performance improvements.

Performance improvements

Significant performance gains were achieved by avoiding extra calls to setState() and render() by ensuring the order of change notifications to occur top-down, matching React's natural flow. Performance tests and benchmarks are discussed in #416.

Bugfixes

Some bugs/issues are resolved, related to performance loss and also impure components not re-rendering.

New features added to connect()

The behavior of connect() is now more customizable, by passing additional properties in the options arg. These will be described in the API docs.

New top level API: connectAdvanced()

The new implementation of connect() splits its behavior such that it is now a wrapper around a more-generalized connectAdvanced(). This connectAdvanced() method can be called directly if you have extreme performance needs or want to craft an API different than that of connect(). This will be described in the API docs.

What's next?

We're looking at removing the shouldComponentUpdate optimization. Since this version is much more performant on its own, that isn't needed. This will fix long-standing problems with other libraries that use React's context API. There are workarounds, but things should work without either library authors having to bend over backwards or React having to make API changes.

We will accept bugfixes on the 4.x branch (the 3.x branch will be going away; but the tags to 3.x versions will remain!), but new features should be built against the next branch. We love PRs, so keep them coming!
