Eclipse Collections 10.0 Released

README: The features you want with the collections you need

Thank you to the contributors

Eclipse Collections 9.2 was released in May 2018. The 9.x releases were extremely feature rich and had many contributions from the community. The 10.0 release is even more so. There were 18 contributors in the 10.0 release. This is outstanding! Thank you so much to all of the contributors who donated their valuable time to making Eclipse Collections more feature rich and even higher quality. Your efforts are very much appreciated.

Too many features for one blog

There are so many features included in Eclipse Collections 10.0, that it is going to take me a bit longer to write good examples leveraging all of them. So I have decided to break this release blog into a few parts. This part will purely be a summary.
