1. Zdenek Brabec (Pure) - What is new in Go 1.25

Go 1.25 has arrived! In this session, we’ll cover all the significant upgrades you need to know, including improvements in the tools, runtime, compiler, linker, and standard library. Key new items include:

• A new experimental garbage collector, available for opt-in use. go.dev
• A new encoding/json/v2 package, also experimental, for better JSON handling. go.dev
• The addition of one entirely new package as part of the standard library. go.dev
• Updates and changes to GODEBUG settings, as well as port-specific enhancements. go.dev

We’ll not only look at what changed, but also explore why these changes matter, how they affect real-world Go development, and where you can try out the experimental features and give feedback.

2. Mila Nguyen (STRV) - Catch Me If You Can: Monitoring Go Services in AWS

Production bugs are like criminals — they leave traces, but only if you know where to look. In this talk, we’ll don our detective hats and instrument a Go backend service running on AWS. We’ll cover setting up error tracking, performance dashboards and database profiling. By the end, you’ll be ready to catch tricky issues in the act instead of being blindsided.

3. Vilibald Wanca - First talk from new cycle about good practices and patterns in Go
