oapi-codegen v2.5.0 is out 🚀📢

A host of new functionality, bug fixes, and the notable big changes:

• Begone optional pointers! (optionally)
• Generating omitzero JSON tags, with x-omitzero
• Using OpenAPI 3.1 with oapi-codegen (with a workaround)
• Defining your own initialisms
• Minimum version of Go needed for oapi-codegen is now 1.22.5

Looking back at oapi-codegen's last year

This last couple of weeks, there have been a couple of big-ish things in oapi-codegen land:

• a big release for the net/http middleware (and a couple of small patch releases) which namely boasts better - or IMO, actually usable! - error handling
• the basis of our (current) governance process for the project
• an example of how to use oapi-codegen with OpenAPI 3.1 specs (as a short-term, until we support OpenAPI 3.1)

Just put the finishing touches on the latest release of oapi-codegen: v2.4.0 includes:

• #OpenAPI Overlay functionality

• Improved multi-file OpenAPI spec support

• Several other features and bug fixes

Very excited to be a guest on tomorrow's @cupogo and to chat about oapi-codegen, #OpenAPI and Go!

For the last ~7 weeks on-and-off rewriting the documentation for oapi-codegen which has needed a fresh version for a bit of time. On top of that, I've spent pretty much the last two days solidly finishing it off, and am very glad to have just merged it!

Documentation can be difficult to do - especially if you're redoing it all in one go - but am hoping it's in a much better place for new and existing users alike!

Also introduces a CONTRIBUTING.md for the first time, and I ended up adding 14 new examples to the examples directory because I couldn't quite remember how things worked 😅

How do you represent a JSON field in Go that could be absent, null or have a value?

Why it's surprisingly hard to work out a field has been sent or whether it's explicitly null, when using Go's `encoding/json`.
