Thanks for the input, all. I'm now convinced that retaining the current odd/even scheme has concrete benefits and am happy to continue doing it. Richard > On Mar 2, 2021, at 10:36 AM, Phyx wrote: > > I am also against not using the odd/even versioning scheme. > > My objections are similar

I am also against not using the odd/even versioning scheme. My objections are similar to what Edward mentioned in that adding "junks" at the end of the build number is problematic for packagers of the toolchain where the packaging has its own way to mark something pre-release. If GHC were to

As ben says, a lot of our tools have made choices over time that make having the odd vs even convention super easy to support for compiler and library devs doing experiments with ghc builds that are based off master. No matter what, any naming scheme is a social construct for communicating with

In the past I've gained non-zero utility from having the spacer there to allow me to push patches in to allow HEAD builds while features are still in flux. Some of those in flux changes -- to my mild chagrin -- made it out to hackage, but were handled robustly because I wasn't claiming in the code

Hi, I generally would like +0.1 steps, but mostly because it causes less head-scratching to everyone new to Haskell. Basically the same argument as Richard says. I can't comment on how far head.hackage (or any tool relies) on odd version numbers, I certainly never have. Given that it's all

It makes determining if a ghc build was a dev build vs a tagged release much easier. Odd == I’m using a dev build because it reports a version like majormajor.odd.time stamp right ? — we still donthat with dev /master right? At some level any versioning notation is a social convention, and this

GHC 9.1?

2021-03-01 Thread Richard Eisenberg
Hi devs, I understand that GHC uses the same version numbering system as the Linux kernel did until 2003(*), using odd numbers for unstable "releases" and even ones for stable ones. I have seen this become a point of confusion, as in: "Quick Look just missed the cutoff for GHC 9.0, so it will
