If you instead look at the over 500 kloc of the Zig source compared to the 70 kloc of the Odin one, it’s a bit clearer why the delay happened: the goals of Zig kept expanding.

But not only that: ”juicy main” and Io is something that could have been in Zig from the early days and yet it isn’t. In the Io case it’s Zig pivoting from ”we have colorless async!” to no async, to Io.

In other words, Andrew is still experimenting with the language (and more is to come, like ranged integers). This is not the signs of a maturing language, it a language still very much in flux, trying to find its form.

The contrast to Odin is that for the last 2-3 years it has had minimal syntax tweaks, and is essentially in release candidate mode for the language.

Even if Zig didn’t need more changes, it would still need that stabilization period.

This tells us Zig is still rather far from 1.0.

I wonder what Andrew is thinking about all this.

Just being ambitious isn’t necessarily good. Look at Perl6.

This version focuses on tightening semantics, improving type inference, and cleaning up edge cases rather than adding new features. Some parts of the standard library (like matrices) have also been reworked.

The goal is to stabilize behavior and reduce inconsistencies before starting the 0.8 cycle.

C3 is aiming to stay close to C in terms of control and predictability, while reducing complexity in everyday use.

One thing that tends to be overlooked when discussing changes is the ecosystem effect of frequent changes.

A language that breaks frequently doesn't just impose upgrade work on apps, but also discourages the creation of long-lived libraries and tools. Anything that sits between the language and the user (linters, bindings, frameworks, teaching material, tutorials etc) has to to some degree "chase the language"

This means that the ecosystem will skew toward very actively maintained libraries and away from "write once then leave it alone" libs. And this the trade-off is reasonable during early language design, but it's worth acknowledging that it has real consequences for ecosystem growth.

One should note that other newer languages have put significant effort into minimizing this churn, precisely to allow the latter type of ecosystem to also form. So it's kind of an experiment, and it will be interesting to see which approach ends up producing the larger ecosystem over time.

Yes, I understand that is the opinion in the Zig community. As an outsider, it seems odd to me to pick a language that I constantly need to maintain.

>> However, the outlook for a Zig 1.0 is bleak from what I gather from Zig social forums: the most optimistic estimate I’ve heard is 2029 for 1.0.

> Funny you see it as bleak when most of the community sees it as the most excitinh thing in systems programming happening right now.

You misread that one. I was talking about the odds of seeing a 1.0 version of Zig soon.

> I think you comment is in bad faith, all the big zig projects say that the upgrade path is never a main concern, just read HN comments here or on other zig threads, people ask about this a lot and maintains always answer.

Maybe you didn't read what I wrote carefully enough. This is part of the protectiveness from the Zig community that prompted me to write in the first place.

WITHIN the Zig community it is deemed acceptable for Zig upgrades to break code. Consequently it becomes simple survivor bias that people who use Zig for larger projects don't think that this is a major concern BECAUSE IF THEY FELT IT WAS A CONCERN THEY WOULD NOT USE ZIG.

Whether programmers at large feel that this is a problem is an unknown still, since Zig has not yet reached to point of general adoption (when people use Zig because they have to, rather than because they want to).

However, it is INCORRECT to state that just because a language is not yet 1.0 it needs to break older code aggressively without deprecation paths. As an example, Odin removed the old `os` module and replaced it with the new "os2". This break was announced half a year in advance and lots of thought was put into reducing work for developers: https://odin-lang.org/news/moving-towards-a-new-core-os/

In the case of C3, breaking changes only happen once a year with stdlib going through the general process of deprecating functions long before removing them.

I wanted to highlight how these are quite different approaches. For established languages, this is of course even more rigorous, but neither C3 nor Odin are 1.0, and still see this as valuable and their communities then end up expecting it.

So please understand that when you say "it's never a main[sic] concern", this is simple survivor bias.

* except for having unused variables. Those are so dangerous the compiler will refuse the code every time.

There are similar hidden quirks in the language that will need to be addressed at some point, such as integer promotion semantics.

To address the question about stability: the Zig community are already used to Zig breaking between 0.x versions. Unlike competitors such as Odin or my own C3, there is no expectation that Zig is trying to minimize upgrading problems.

This is a cultural thing, it would be no real problem to be clear about deprecations, but in the Zig community it’s simply not valued. In fact it’s a source of pride to be able to adapt as fast as possible to the new changes.

I like to talk about expectation management, and this is a great example of it.

In discussions, it is often falsely argued that ”Zig is not 1.0 so breaks are expected” in order to motivate the frequent breaks. However, there are degrees to how you handle breaks, and Zig is clearly in the ”we don’t care to reduce the work”-camp.

If someone is trying to get a more objective look at the Zig upgrade path, then it’s worth keeping in mind that the tradition in Zig is to offload all the work on the user.

The argument, which is frequently voiced, is that ”breaking things will make the language get better and so it’s good that there are language breaks”

It is certainly true that breaking changes are needed, but most people outside of the Zig community would expect it to be done with more care (deprecation paths etc)

Secondly, it should perhaps be a concern for Zig, now at 10 years old, to still produce solidly breaking code every half year.

10 years is the common point where languages go 1.0. However, the outlook for a Zig 1.0 is bleak from what I gather from Zig social forums: the most optimistic estimate I’ve heard is 2029 for 1.0.

This means that in the future, projects using Zig can still expect any libraries and applications to bitrot quickly if they are not constantly maintained.

Putting this in contrast with Odin (9 years old) which is essentially 1.0 already and has been stable for several years.

Maybe this also explains the difference in actual output. For example the number of games I know of written in Odin is somewhere between 5 to 10 times as many as Zig games. Now weighing in that Zig has maybe 5 or 10 times as many users, it means Odin users are somewhere between 20-100 times as likely to have written a playable game.

There are several explanations as to why this is: we could discuss whether the availability of SDL, Raylib etc is easier on Odin (then why is Zig less friendly?), maybe more Odin has better programmers (then why do better programmers choose Odin over Zig), maybe it’s just easier to write resource intensive applications with Odin than Zig (then what do we make of Zig’s claim of optimality?)

If we look past the excuses made for Zig (”it’s easy to fix breaks” ”it’s not 1.0”) and the hype (”Zig is much safer than C” ”Zig makes me so productive”) and compare with Odin in actual productivity, stability and compilation speed (neither C3 nor Odin requires 100s of GB of cache to compile in less than a second using LLVM) then Zig is not looking particularly good.

Even things like build.zig, often touted as a great thing, is making it really hard for a Zig beginner (”to build your first Hello World, first understand this build script in non-trivial Zig”). Then for IDEs, suddenly something like just reading the configuration of what is going to be used for building is hidden behind an opaque Zig script. These trade-offs are rarely talked about, as both criticism and hype is usually based on surface rather than depth.

Well, that’s long enough of a comment.

To round it off I’d like to end on a positive note: I find the Zig community nice and welcoming. So if you’re trying Zig out (and better do that, don’t let others’ opinions - including mine - prevent you from trying things out) do so.

If you want to evaluate Zig against competitors, I’d recommend comparing it to D, Odin, Jai and C3.

Other improvements in this release:

- Much improved MSVC cross compilation

- Quality-of-life fixes

- Custom LLVM builds to reduce external dependencies

This version departs from its rather uncommon module-based generics, but doesn't go all the way to C++ style templates. Instead generics can be grouped for common constraint checking on template parameters and instantiation. As usual it also contains fixes and additions to the stdlib.

I keep revisiting goto though. I like it a lot for its simplicity.
