Kind of a lot, but here’s the email from Mapbox; links in the body returned errors:
Hey pai-webservant,
Mapbox is deprecating support for Mapbox Studio Classic styles on June 1st, 2020 and you’ve made requests using those styles in the last 30 days. Below is a quick guide so you’re prepared for these changes.
As a reminder, you have not been able to modify these styles since March 31, 2020 and these styles stopped receiving map data updates in Q1 2018.
The first 1,000 developers who migrate from Classic Styles to modern styles in the next 2 weeks and respond to this email will receive free Mapbox stickers!
1. What’s happening?
On June 1, requests to Studio Classic styles or projects from new apps and websites will return 4xx responses. Requests from existing websites and apps will continue working for a period of time as we work with you to move off the service, however we will lower our operational support for our legacy API endpoints that serve Classic styles. This means no feature requests or bug fixes except to address critical security vulnerabilities. This also means a lower SLA for these endpoints relative to our modern endpoints.
If you’ve already stopped using Studio classic styles in your web or mobile app, then please disregard the rest of this email.
2. What are the benefits of upgrading my Classic styles?
Some of the immediate benefits of upgrading include: daily map data updates validated by Mapbox (Classic styles stopped receiving map data updates in Q1 2018), the ability to customize and style your maps with Style Components in Studio, and significantly improved load times and global reliability. After June 1, Mapbox will not be prioritizing operational improvements to the endpoints that serve Classic styles.
3. Where can I see the Classic styles associated with my account?
If you’re using a custom Classic style created via Studio Classic or a classic project created in Mapbox Editor, you can see your Classic styles listed here: https://studio.mapbox.com/classic/.
If you’re receiving this email, but you don’t see any styles listed at the above link, follow this migration guide to locate the styles used in your application.
4. How do I upgrade from Classic styles to modern Studio styles?
If you have an interactive slippy map, read our guide on migrating to the modern Static Tiles API. If you’re using a Classic style as a fallback for browsers that don’t support WebGL, use this tutorial to upgrade.
Note: the Static Tiles API can return 512×512 map tiles, which cover 4x the area of the 256×256 tiles associated with Classic styles. Be sure you include the tileSize: 512 and zoomOffset: -1 options so you don’t incur 4x as many tile requests as necessary and so that your labels, icons, and other map features don’t appear smaller than expected.
If you’re using the Legacy Static Images API to embed static map images in your website or application, read our guide on migrating to the modern Static Images API.
If you need additional resources to help upgrade to modern Studio styles you can use our Developer Network and select the “Legacy Applications” skill in your search.
If you have any questions about the above, please reach out to our support team or your Technical Account Manager.
