With 2025.1.1 released yesterday, it felt like a good time to review 2024 and all the improvements made to jswzl during the year. And a bit of a look ahead to what will come in 2025! jswzl.io/post/2024-in-review

Our build system was apparently still recovering from New Year's, and the build for the 2025.1.1 server didn't contain the full set of changes, which broke some functionality😱 If you have already installed 2025.1.1, it's recommended that you go and re-download the server build

This is such wonderful advice that it inspired a whole blog post on the subject of manually reviewing JavaScript! Check it out! jswzl.io/post/the-role-of-ma…
BB Tips that no-one wants to hear #1. You need to manually read that js file. Your automated tooling is missing things. I guarantee it.

It's been a year now since the first release of jswzl. Time has flown! 🤯 It's amazing to hear from customers regularly about how jswzl has helped them find vulnerabilities more easily. And we now have paying customers in 16 countries! 🥳 I look forward to building on that in year two and making the tool even more effective for users.
