2023-06-19 - We don’t use ChatGPT to code sitespeed.io but we prompt it to write a blog post about sitespeed.io as it was Steve Jobs writing it and it turned out quite good.
2021-12-23 - Here’s my wish list on how we all can make sitespeed.io better.

2019-05-21 - Stop what you are doing and try out the new 9.0! It will blow your mind :) You get a lot of more insights of where your page spends the CPU time and we also makes it easier to pinpoint 3rd party problems.
2019-04-29 - When we released 8.0 we pushed the most wanted feature, scripting that makes it possible to test multiple pages in a user journey. Since the release we pushed many small additions and I wanted to go through a couple of them.
2019-03-30 - 8.9.0 uses the Third party web project to categorise third party requests.
2019-02-17 - Last seven days we pushed a lot of small fixes and features!
2019-01-21 - Finally it is here, the most wanted feature by users … test multiple pages within the same browser session, scripting the page and choosing yourself when to run your tests.

2018-01-24 - In the new release we focused to make the WebPageTest experience better. Many thanks to Jean-Pierre Vincent who contributed a lot to this release!
2017-12-12 - We got something for you to play with during the holidays! Both Browsertime and sitespeed.io got an alpha Docker container (a real early release). The Docker image is bundled with WebPageReplay. If you want to focus on finding regressions in your frontend you need try this out!
2017-11-27 - We got some big news - sitespeed.io 6.0, Browsertime 2.0, The Coach 1.0 and PageXray 2.0 is here. We moved to NodeJS 8, made a lot of small improvements and focused on making plugins more powerful.
2017-11-02 - After the release of 5.0 back in April we’ve (Peter/Tobias/Jonathan) decided to take things to the next level and are introducing the coming 6.0.

2017-02-14 - Whitelisting usertimings, S3 storage support, and annotation linking for Grafana to results oh my!
2017-01-23 - Recently Google started to heavily use User Timings to track some of their ads implemented on various sites. While generally I would commend anyone that takes advantage of the performance API, sometimes that can also have repercussions and cause issues for other tools.
2016-12-22 - It is soon Christmas so we need to release 4.3 with two cool things! A new updated version of PerfCascade that adds content type icons to the waterfall graph and a bug fix for getting correct firstVisualChange when testing as an emulated mobile device.
