Compile-Time OpenTelemetry Instrumentation for Go (https://golangweekly.com/link/188129/rss) — No more hand-written instrumentation or eBPF agents needed, as OpenTelemetry's compile-time instrumentation for Go is now stable. It uses -toolexec to inject telemetry automatically, but v1's library coverage has some limits worth noting.

IN BRIEF:
-
14 years ago Rob Pike proposed removing string(int) (https://golangweekly.com/link/188130/rss) – there's an update! It's a likely decline but comments are open. The more recent conditional expression proposal (https://golangweekly.com/link/188131/rss) is also looking likely to suffer a similar fate.

It’s not open source (yet) but they go deep into the design here, complete with plentiful illustrations.

THREE GO PROPOSALS:
-
Felix Geisendörfer has proposed adding an rss profile type (https://golangweekly.com/link/184973/rss) to runtime/pprof to broaden the view of overall physical memory usage.
-
Cherry Mui proposed enabling AMD64 architecture-specific SIMD intrinsics (https://golangweekly.com/link/184974/rss) by default. There's still work to do, though, so it's not going to happen till Go 1.28. (https://golangweekly.com/link/184975/rss)
-
Neal Patel has suggested go doc gets a -test option (https://golangweekly.com/link/184976/rss) to include symbols from test files in documentation, such as may be useful for LLM agents.

Zero-Config Go Heap Profiling (https://golangweekly.com/link/184627/rss) — Go’s runtime samples heap allocations automatically, but the linker disables this in apps that don’t import runtime/pprof or net/http/pprof. This tour of runtime.mbuckets and /proc/<pid>/mem is a good read if you’ve wondered where pprof data actually lives, or how to grab a heap profile from a process you can’t redeploy.

NEW GO PROPOSALS:
-
Go co-designer Robert Griesemer has made a proposal to add a StringLen function to go/constant (https://golangweekly.com/link/184631/rss).
-
Should error message text be explicitly excluded (https://golangweekly.com/link/184632/rss) from the Go 1 compatibility promise? The proposer cites a comment in net/http (https://golangweekly.com/link/184633/rss) saying an error message can't be changed as evidence of the current ambiguity.
-
🔒 Neal Patel of the Go security team proposes adding 'profiles' to crypto/tls (https://golangweekly.com/link/184634/rss) that bound what the rest of tls.Config's vast array of settings can do.
Gojit: A Revived JIT Compiler in Go (https://golangweekly.com/link/184635/rss) — Go’s AOT compilation makes JIT unnecessary in most cases, but what if you’re writing an emulator or interpreter that would benefit? This post revives a 2014 experiment (https://golangweekly.com/link/184636/rss) for modern Go and solves the problem of letting JIT-generated code call back into Go functions without crashing the GC. Aaron explains more ▶️ in this five-minute video. (https://golangweekly.com/link/184637/rss)

Go 1.27 will fix a generic type inference gap (addressed in this just-accepted proposal (https://golangweekly.com/link/182930/rss)). S{f: g} will finally work anywhere s.f = g does.
-
⚠️ CVE-2026-4427 (https://golangweekly.com/link/183030/rss) is a high-severity DoS vulnerability in pgproto3, the library behind pgx (https://golangweekly.com/link/182932/rss), the popular Go Postgres driver (upgrade to 5.9.0+ (https://golangweekly.com/link/182933/rss)).

IN BRIEF:
-
⭐ Go 1.26.2 and 1.25.9 have been released (https://golangweekly.com/link/183620/rss) including ten security fixes covering os, html/template, crypto/x509 and more. Microsoft's builds (https://golangweekly.com/link/183621/rss) are also available.
-
First proposed in 2015, the implementation of type-inferred composite literals (https://golangweekly.com/link/183622/rss) has now become a 'likely accept'.
-
There's a Go compiler tweak (https://golangweekly.com/link/183623/rss) in the pipeline that optimizes switch statements using lookup tables, making certain constructions >2x faster.

🇬🇧 GopherCon UK (https://golangweekly.com/link/183624/rss) is taking place over August 11-13 in London. Early bird tickets (https://golangweekly.com/link/183625/rss) are now available. If you want to see the caliber of the event, you can watch last year's talks here. (https://golangweekly.com/link/183626/rss)
Calling a Rust Library from Go Without Cgo (https://golangweekly.com/link/183627/rss) — cgo (https://golangweekly.com/link/183628/rss) is useful, but there are often reasons to avoid it (https://golangweekly.com/link/183629/rss). Can you call a Rust library from Go without Cgo or WebAssembly? Yes, but it’s tricky, has risks, and isn't advised for every situation.

💡 purego (https://golangweekly.com/link/183678/rss) offers a similar, though more general, approach to this problem.
A Fast Immutable Map in Go (with Tradeoffs) (https://golangweekly.com/link/183630/rss) — constmap (https://golangweekly.com/link/183631/rss) 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.
