Congratulations 
- that’s a massive amount of work! Small typo:
a better appraoch—less prone to typos

{t} is shorthand for @tagName() and @errorName()
I didn’t know I needed this feature, but I’m sold on it.

Every single one is so sticker-worthy!
Congratulations on the release. most of the transition in my library was easy.
I am hitting one snag: How do I print an array of strings as an array of strings? {s} used to work not it does not

Possibly unrelated - master branch builds (currently pointing to 0.15.1) throw a 404 when downloading from Download ⚡ Zig Programming Language
damn this thing is fast! great work on the release! looking forward to the improvements to come

Congrats, looking forward to giving it a whirl!
Do you track/publish download stats? Just wondering about the breakdown for what platforms people are now developing on.
Omg… now I have to start recoding my IO and boundedarrays 
Dear users: expect a plethora of threads from this noob.

Congrats on the release!
(update: ah cheered to soon unfortunately, see the PS)
Btw, my emulators (GitHub - floooh/chipz: 8-bit emulator experiments in Zig) are now fast(-ish) in debug mode with the x86 backend (well fast enough to easily run in realtime in debug mode) - previously they suffered heavily from a large switch-statement that was evaluated with a linear search.
Cool stuff
PS: ah doh, looks like I spoke too soon, I tested on Windows - but it just occured to me that the problems happened on Linux, and there 0.15.1 indeed still seems to have a ‘linear-search-in-switch’ performance problem. I guess Windows still uses the LLVM backend? Tbf though I was wondering why the build times on Windows wasn’t any faster than I remembered… and on Linux this is indeed drastically reduced.

ArrayList → array_list.Managed and BoundedArray → feel just right!

Waiting for zls updates.

Either Debian 13 coming out or this release made zig build --watch -fincremental work for me. Which is awesome! The rebuilds are literally a few ms.

How unfortunate I am to be working on a text editor amongst an overhaul to the io… Otherwise, great update!

Performance datapoint:
- simple pure-zig serialization library for messagepack, no dependencies
- approx. 3000 lines of code
- executes all the unit tests
- 6 year old laptop, x86_64-linux (debian 13)
- debug mode
zig 0.14.0: 19.829s
zig 0.15.1 (force llvm): 11.781s
zig 0.15.1: 6.714s
66% faster!!!
Reproduction steps
# Use anyzig so it auto-detects the zig version from build.zig.zon.
# Run multiple times so that anyzig doesn't have to download zig.
# Use fastest times.

cd lizpack

Nothing to worry about, the Io overhaul will be much more straightforward than Writergate. The worst is already behind us. Writergate required effectively rewriting all stream implementations; meanwhile, the Io overhaul will be trivial updates like this:
-var file_reader = file.reader(&.{});
+var file_reader = file.reader(io, &.{});

So does incremental watch already work on windows with -fincremental -Dno-bin or is it still not usable because of linker availability?
I wonder how advisable it is to start using await and async as function/variable names.
