umap-project/umap 2.0.0 on GitHub

This release is inauguring a new era in versionning uMap: in the future, we'll take care of better documenting breaking changes, so expect more major releases from now on. More details on how we version.

The main changes are:

on the front-end side, we now use native ESM modules, so this may break on old browsers (see our ESlint configuration)
on the back-end, we upgraded to Django 5.x, which drops support for Python 3.8 and Python 3.9.
the OpenStreetMap OAuth1 client is not supported anymore (now deprecated by OpenStreetMap.org)
license switched from WTFPL to AGPLv3: having an OSI valid licence was a request from our partners and sponsors (#1605)

More details below!

Breaking changes

upgrade to Django 5.x drops support for Python < 3.10
django-compressor has been removed, so umap compress is not a valid command anymore (compress is now done in the collectstatic process itself) (#1544, #1539)
removed support for settings starting with LEAFLET_STORAGE_ (deprecated since 1.0.0)
removed support for deprecated OpenStreetMap OAuth1 backend in favour of OAuth2 (see below)
FROM_EMAIL setting is replaced by DEFAULT_FROM_EMAIL, which is Django standard

Migrate to OpenStreetMap OAuth2

create a new app on OSM.org: https://www.openstreetmap.org/oauth2/applications/
add the key and secret in your settings (or as env vars):
- SOCIAL_AUTH_OPENSTREETMAP_OAUTH2_KEY=xxxx
- SOCIAL_AUTH_OPENSTREETMAP_OAUTH2_SECRET=xxxx
if you changed AUTHENTICATION_BACKENDS, you need to now use "social_core.backends.openstreetmap_oauth2.OpenStreetMapOAuth2"
run the migration command, that will migrate all accounts from OAuth1 to Oauth2:
umap migrate
