I'm Jarosław, and I started The Stack Sentinel to make release notes easier to act on. A changelog tells you what changed; it rarely tells you whether you should care, what might break when you upgrade, or what to check first. That is the gap I want each article here to close, and every claim has to trace back to a primary source I link.

By day I work in corporate trust at a global bank, as a Senior Specialist in client and market risk management. It is the kind of work where one missed detail in a long legal document becomes a real problem, so cross-checking every statement against its source is a habit, not a feature. It is also where I got hands-on with AI: I designed an AI-driven process automation library on Microsoft 365 Copilot that cut manual processing time in core transaction workflows by up to 93%, with maker-checker review and version control built in, so every automated output still gets a human check.

This site runs on the same idea. I built it and the pipeline behind it myself: sources come from official release notes and project blogs, drafts are prepared with AI-assisted tools and checked against those sources by separate AI reviewers, and nothing goes live until I have read it and approved that exact version.

I studied Information Technology at Kamianets-Podilskyi Ivan Ohiienko National University, and new technology, programming, software security and AI have been my favorite rabbit holes ever since. If you spot a mistake or want a release covered, write to me; I read every message.

The Stack Sentinel is my independent personal project. It is not affiliated with or endorsed by my employer, and nothing here represents my employer's views.
