# Issue #612: A plan to bring generic collections to Go 1.28 — Go Weekly

**[Golang Weekly](https://daily.dev/sources/glw)** · 2 min read · 8 upvotes · 0 comments

## Summary

Go Weekly Issue #612 covers a major umbrella proposal from Go's Collections working group targeting Go 1.28, which plans to add generic collection types to the standard library including a canonical set.Set type, hash-based maps and sets with custom hashers, an ordered map, and a generic binary heap. Other highlights include a deep dive into pgx's CollectRows performance improvements landed in pgx 5.6, a pattern for wrapping errors with defer, an explanation of how Swiss Tables replaced Go's old map bucket design, and several library releases: Gore 0.7 (Go REPL), Goph 2.0 (SSH client), Wish 2.0.2, jsonparser 1.6, Milvus 3.0, and req 3.60.
