Zipkin 2.20
Zipkin 2.20 is our first big release of 2020.
Most notably, the Lens UI is now default, retiring the classic UI. This is a big deal for many sites, and your continued feedback is especially important now. Please send any praise, concern or questions to Gitter and add issues as appropriate.
First, let's thank @eirslett and @zeagord for leading the last incarnation of the classic UI. Since @eirslett rewrote the former scala+javascript UI into a single-page, pure javascript 5 years ago, we had 38 contributors. @eirslett set the architecture in place for an order of magnitude more people to become involved, and for a new leader @zeagord to emerge. The classic UI had deceptively simple features, in so far as they are hard to replicate. This is evidenced by so few efforts managing to come close to feature parity, even with a lot of full time staff allocated to the task. Suffice to say, zipkin-classic is a very very good product and has a special place in the history of open source distributed tracing, especially volunteer open source.
Next, let's thank LINE for contributing a new codebase to the project, and further the time of @tacigar to move mountains to push UX forward while simultaneously reaching for feature parity. Along the way, @drolando played MVP of testing, finding all the edge cases in practice at Yelp. Finally, we owe as a community a great thanks to @anuraaga who single-handedly filled all the remaining feature gaps to ensure this release would have the least disruption to you. The last year and a half has not been easy, but we think it has been worth it, as you can now reach a new UI without the trouble of a platform switch.
While we noted MVPs, it is ultimately you, the end users and sites who have been with us years or only days. Please do engage if you have suggestions or contributions to offer. We're only a chat away!
As a finale, let's look at a trace from Netflix from the last version of the classic UI and our new UI Lens. We think you'll agree, they are both good products. Here's to another 5 years!
