v1.3.0 - the "fix a lot of stuff and make it faster" release

So many changes! Thank you to all contributors, you're great! 😎

Here are the highlights:

• @Hendrikto found some nice performance improvements by introducing an internal raw type, that you'll get automatically by just keeping on using the Text/Textf and Raw/Rawf functions. He also fixed the benchmarks, which turned out to actually measure the wrong thing because of behind-the-scenes compiler optimizations in the benchmark code itself. Thanks, @Hendrikto!
• I've added a new experimental x/slices package, as a way of letting people have the Map/Filter/Reduce workflow that's been requested so many times over the years. Note that the x package is for experimental stuff, so it doesn't have the same compatibility guarantees as the rest of the gomponents module.

There are a lot of smaller additions, fixes, and performance improvements. See the full list below.

Again, thank you to all contributors!

PS: You'll notice my coding agent @maragubot as a contributor. Rest assured, I still review and merge all changes to gomponents manually.

Full Changelog: v1.2.0...v1.3.0

v1.2.0 - `components.JoinAttrs` and performance improvements

This change adds a new components.JoinAttrs component, which is useful for joining attribute values (such as the often requested class attribute merging).

Also, contributors added some missing/new HTML elements and attributes. Thanks!

Also, some performance improvements, which should help with less memory allocation especially in newer Go versions.

Full Changelog: v0.22.0...v1.0.0

v1.0.0-beta1 - The API is now stable!

This release marks the first beta of a 1.0.0 release. This means that I'm committed to this API going forward,
and breaking changes will only happen in a v2 that hopefully will never come.

The only major change from v0.22.0 is that the module is in a new namespace: maragu.dev/gomponents
Because of Go module dependency pinning and the Go module proxy, I don't think this will have much of an impact on people using the library, but I'm being cautious with a beta release and testing things extensively.

If you find any issues, please report them, either on the discussion attached to this release, or open a separate issue.

What's Changed

• ⚠️ Move module to maragu.dev/gomponents namespace by @markuswustenberg in #215
• Fix example app to use maragu.dev/gomponents module path by @markuswustenberg in #216

Full Changelog: v0.22.0...v1.0.0-beta1

v0.22.0 - the "remove SVG package" release

The svg package is no more. Note that the html.SVG element still exists, and SVGs can easily be embedded in the HTML using g.Raw.

What's Changed

• ⚠️ Remove SVG package by @markuswustenberg in #214

Full Changelog: v0.21.0...v0.22.0

v0.21.0 - the "Groups are just slices" release

Group is now a type instead of a function, which is technically a breaking change, but is not expected to impact many codebases, if any at all. Special thanks to @deitrix for suggesting this design! 😎

What's Changed

• Drop support for Go 1.16 and Go 1.17 by @markuswustenberg in #203
• Add full example app by @markuswustenberg in #204
• Make Group a type by @markuswustenberg in #202

• Test on Go 1.23 in CI by @yardenshoham in #193

v0.20.4 the "Iff, no really only if" release

This release adds the Iff function, which takes a callback function instead of the Node that regular If does, for those cases where you need to conditionally add components but they can fail for some reason (but usually nil pointer panics). Thanks, @JulienTant!

What's Changed

• Add dir by @amrojjeh in #176
• Add a Iff helper by @JulienTant in #172
• Add datetime attribute by @JulienTant in #177
• Adjust documentation on Iff by @markuswustenberg in #179

New Contributors

• @amrojjeh made their first contribution in #176

Full Changelog: v0.20.3...v0.20.4

v0.20.3 - the "opinionated node name collision choice" release

What's Changed

• Deprecate DataAttr, StyleAttr, TitleAttr, FormEl by @markuswustenberg in #174
  This doesn't mean those elements and attributes have gone away, but that I've chosen one to be the "main" version without a suffix.
  See the PR at #174 and the issue at #170 for a discussion and the chosen solution.
  This is a non-breaking change, and the deprecated nodes will stay, probably forever.
• Add script's integrity and crossorigin attributes by @JulienTant in #173
• Add LabelAttr and List attributes by @markuswustenberg in #175

New Contributors

• @JulienTant made their first contribution in #173
