v0.43.0-beta.1

[jfirebaugh]

🌞 ⛰ 🎉 Hi all! The next release is going to be a big one, with the marquee feature being client-side hillshading.

Before	After

To ensure the final release is as solid as possible, we're doing a brief beta period. Today we're releasing v0.43.0-beta.1, and we aim to release v0.43.0 in about a week. We hope you'll give the beta a spin, try out the new features, and let us know if you spot any issues. In particular, I'd like to give a shout out to recently active contributors @andrewharvey, @vicapow, @jingsam, @stevage, @bartvde, @musicformellons, and @pathmapper. Your PRs and bug reports have been great, and we'd love it if you tried out the beta.

The complete changelog follows. The release will be available on npm and the CDN shortly after this PR is merged.

🎉 thanks @jfirebaugh !

[stevage]

Awesome! I'm really excited - lack of good terrain styling has been the big thing I've been missing from Tilemill. (I want to re-create my old cycletour.org ).

Where is the right place to give feedback?

Also, I don't see mention of elevation-coloring (ie, green at low elevation, white at high elevation). I find it makes a huge difference for being able to visually parse a map to see where the mountains are. Is this on the radar too?

Oh, I also noticed this snippet comparing old hillshading and client hillshading, which others may be interested in: https://www.mapbox.com/bites/00357/

elevation-coloring (ie, green at low elevation, white at high elevation).

@stevage that should be possible after #3889 hopefully.

[jfirebaugh]

v0.43.0-beta.1 is now available via npm and CDN. Note that it's tagged as next rather than latest on npm, so 0.42.2 will continue to show up on the package home page.

@stevage Feedback via bug reports and feature requests as you normally would.

[vicapow]

congrats! will take a look now

[stevage]

Is there anywhere to see documentation for the new source and layer types?

[andrewharvey]

Is there anywhere to see documentation for the new source and layer types?

@stevage I don't think it's published yet, and only the latest version of docs are hosted by Mapbox, so you'll need to run the docs locally with:

npm run start-docs

Which should show the docs at http://localhost:8080/mapbox-gl-js/style-spec

...or if you're only interested in the hillshade example you can peek at https://github.com/mapbox/mapbox-gl-js/blob/master/docs/pages/example/hillshade.html

[stevage]

Sorry, I think there's a bit of assumed knowledge here I'm missing. I don't do a lot of checking out pre-release code for local building etc. Do I need to check out the whole repo to do that? Just doing npm install mapboxgl@next && npm run start-docs didn't work.

Anyway, I think this is what I was looking for.

[andrewharvey]

Yeah you need to clone this repo, then either

npm install
npm run start-docs

or

yarn install
yarn run start-docs

The HTML docs are much nicer than the style spec JSON, but it's your preference 😉

[vicapow]

Sorry, for the delay in responding. The beta seems to be working fine for me. Will continue to use it and report back if there's issue. Nicely done!
