Eclipse Collections 10.3 Released
This is the release we’ve been waiting for.
Thank you to the community
Eclipse Collections 10.2 was released in February 2020 and was a relatively small bug fix release after the somewhat monumental 10.0 release. I am happy to say that six months later, the 10.3 release has a lot of new features submitted by our outstanding community of contributors.
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.
If you’re thinking about contributing to an open source project but aren’t sure, check out this great blog from one of our community contributors. In the blog Sirisha Pratha explains some of the benefits she has experienced as she has become an active contributor in the OSS community.
We are always looking for new contributors to join the Eclipse Collections community. Please consider contributing to Eclipse Collections if you are looking for a project to get started on your journey.
Eclipse Collections received an amazing and humbling honor in a Java Magazine article in June when it was named one of “The 25 Greatest Java Apps Ever Written.”

The credit belongs to the entire Eclipse Collections community. Your hard work and patience contributing to this library is being recognized. Congratulations and thank you to our entire community. Keep up the great work! You all rock!
Loads of new features and several contributor blogs
There are so many features included in Eclipse Collections 10.3, that it is going to take me a bit longer to write good examples leveraging all of them. The good news is that I’ve already gotten some help from the community. Some contributors blogged about the features they added before I started writing this blog.
Dirk Fauth wrote a blog where he evaluated whether there would be any performance and memory improvements including Eclipse Collections in NatTable. He also raised an issue for a missing feature, contributed the feature, and then updated the blog!
NatTable + Eclipse Collections = Performance & Memory improvements ?
Some time ago I got reports from NatTable users about high memory consumption when using NatTable with huge data sets…
I thanked Dirk for both the blog and code contribution, and he said something in response on Twitter that I found very inspirational.
IMHO this is the way OSS works. Use it, like it, write about it. Find an issue, report it, fix it, contribute back.
Well done, and well said! This is exactly the spirit of community that keeps me working happily in open source.
A suggestion for future releases and future bloggers
Feature blogging is something I would love to see more of in the future from contributors. This is a great way to make sure the features you contribute get discovered by other developers. This may in turn encourage developers to upgrade to the latest release. It is also a great way to help build your own personal brand, as I will link to your feature blogs from the release blog. I will also be happy to like and retweet your blog and thank you publicly for the contribution. You are saving me time explaining how the feature you added works in the release blog, so trust me I will be very thankful and happy to help socialize your hard work!
