alt Hacker News> As you can see from the version number, this release is not a 1.0 release. In fact, we still haven’t finished discussing what 1.0 means for Servo
Wait, crate versions go up to 1.0?
EDIT: Sorry, while crate stability may be an interesting conversation, this isn't the place for it. But I can't delete this comment. Please downvote it. Mods feel free to delete or demote it.

Hey - Many rust libraries adopt [0-based versioning](https://0ver.org/). That link can describe it more elegantly than I.

If you want to lure Microslop to migrate all their "great" apps to Servo.
Easy, just add bloat code so it will use 5GB of RAM by default, that's instant adoption by MS.
The fundamental problem with Rust versioning is that 0.3.5 is compatible with 0.3.6, but not 0.4.0 or 1.0.0; when major version is 0, the minor takes the role of major and patch takes the role of minor. So packages iterate through 0.x versions, and eventually, they reach a version that's "stable".
If version 0.7 turned out to hit the right API and not require backward incompatible changes, releasing a version 1.0 would be as disruptive as a major version change to your users and communicate through version semantics that it is a breaking change.
Semver declares that version 0.x is for initial development where there is no stability guarantee at all. This is the right semantics for a versioning system, but Cargo doesn't follow this part of semver. Providing stability guarantees throughout the 0.x cycle inevitably results in projects getting stuck in 0.x.
This is one of my biggest gripes with Cargo. But Rust people seem to universally consider it a non-issue so I don't think it'll ever be fixed.
