IN BRIEF:
-
⭐ Go 1.26.2 and 1.25.9 have been released including ten security fixes covering
os,html/template,crypto/x509and more. Microsoft's builds are also available. -
First proposed in 2015, the implementation of type-inferred composite literals has now become a 'likely accept'.
-
There's a Go compiler tweak in the pipeline that optimizes
switchstatements using lookup tables, making certain constructions >2x faster. -
🇬🇧 GopherCon UK is taking place over August 11-13 in London. Early bird tickets are now available. If you want to see the caliber of the event, you can watch last year's talks here.
💡 purego offers a similar, though more general, approach to this problem.
A Fast Immutable Map in Go (with Tradeoffs) — constmap gets you 3x faster lookups and 6x less memory used per key than map, but with several tradeoffs, including only offering string to uint64 mapping, being unable to tell if a key is missing, and increased construction time.

People are using Go for all sorts of fun things and I have a backlog of items that don't fit into the usual flow. You might find some of these things interesting, though!
HOSA: Homeostasis Operating System Agent — “An autonomous nervous system for Linux.” I confess this is above my pay grade, but Fabricio is working on it for his master’s degree and it uses a lot of eBPF which we don’t often see.
