====== Geographic Features Changelog ======

The architecture of the [[configuration:geographic_features|geographic features]] has changed over time. This page describes some of the historical changes.

===== Changes from VuFind® 4.x to 5.0 =====
:!: Starting in VuFind® 4.0, the OpenLayers functionality has been removed and replaced with Leaflet.

Other improvements include: 
  * Improved search results clustering
  * Streamlining of configuration parameters, which are now all located in geofeatures.ini

===== Changes from VuFind® 3.1 to 4.x =====
The VuFind® 3.1.x version of these modules preserved and upgraded the VuFind® 2.x GoogleMap functionality, so that it was compliant with the new Google API key requirements.

:!: Starting in VuFind® 4.0, the GoogleMap functionality has been removed, some [[development:architecture:solr_index_schema#vufind_40|Solr schema details]] have been adjusted, and the Geographic Search & Display modules use OpenLayers exclusively. See [[https://github.com/vufind-org/vufind/pull/995|pull request #995]] to review the Google Map code that was removed.
