leaflet 2.2.3

• {leaflet} is now licensed under the MIT license (was GPL-2) (#958).

• {leaflet} no longer install {sp} by default and attempts to convert object to sf internally before creating a map and warns when it fails conversion (@olivroy, #942).

• The breweries91, atlStorms2005, and gadmCHE datasets are now {sf} objects (@olivroy, #944).

• {leaflet} now requires R 3.5 and above (@olivroy, #944).

• Color palette improvements. All color palette functions now support all {viridisLite} palettes ("magma", "inferno", "plasma", "viridis", "cividis", "rocket", "mako", and "turbo") (@jack-davison, #924).

• Updated vignettes to replace {sp}/{raster} usage with {sf}/{terra} and their corresponding examples. (@jack-davison, #928)

• Updated vignettes to replace {sp}/{raster} usage with {sf}/{terra} and their corresponding examples. (@jack-davison, #928)

• addProviderTiles() will now error if the chosen provider does not match any currently loaded provider (by default, those in providers). This behaviour can be toggled off by setting the new check argument to FALSE (@jack-davison, #929)

leaflet 2.2.2

• Fixed #893: Correctly call terra::crs() when checking the CRS of a SpatVector object in pointData() or polygonData() (thanks @mkoohafkan, #894).

• {leaflet} now has a brand new pkgdown site (@olivroy, #902)

• Replace {viridis} dependency by {viridisLite} (@olivroy, #897)

• addRasterImage now takes options = gridOptions(), so that arbitrary Leaflet layer options can be controlled. (#692)

leaflet 2.2.1

• When addProviderTiles() is used with {leaflet.providers} version 2.0.0 or later, the leaflet-providers HTML dependency produced can be correctly cached by knitr. When used with older versions of {leaflet.providers}, the HTML dependency uses temp files that break knitr's caching mechanism (thanks @qdread, @jaredlander; #884).

leaflet 2.2.0

Features

• Added support for SpatRaster and SpatVector objects from the terra package. (#728)

• leaflet() now uses jQuery 3.6.0 provided via the {jquerylib}package. As a result of this change, the HTML dependencies for leaflet() are included in the dependencies item of the htmlwidget object it returns. (#817, #821)

Bug fixes and improvements

• Use correct license in OpenStreetMap attribution. (#811)

• Use xfun::base64_uri() for base64 encoding instead of markdown and base64enc. (#823)

• Remove dependencies on rgdal and rgeos. (#837)

• Respect option scrollWheelZoom=FALSE. (#827)

• Fixed #866: Correctly call terra::has.RGB() in addRasterImage() for a SpatRaster object. (#869)

v2.1.2

leaflet 2.1.2

Bug fixes and improvements

• Removed S3 warnings found on R devel (#848)

v2.1.1

leaflet 2.1.1

Bug fixes and improvements

• The default marker icon for addMarkers no longer worked, due to the CDN we were relying on apparently being retired. Fixed by pointing to a new CDN. (#782)

• New behavior from tile.openstreetmap.org caused addTiles default tileset to break when viewed under non-https protocol on recent versions of Chrome. Fixed by always using the https protocol to connect to openstreetmap. (#786)

v2.1.0

leaflet 2.1.0

Bug fixes and improvements

• Enable JS function literals (wrapped in htmlwidgets::JS()) to be included in arguments to methods invoked on leafletProxy objects. (JS function literals could already be included with methods invoked on leaflet objects, so this change just brings leafletProxy to parity.) (#420)

• Add missing CSS rule to show <img> in right-pane and left-pane (rstudio/rmarkdown/issues#1949, #770)

• Allow for hidden but not suspended leaflet maps to queue calls (such as add raster images) until they are rendered. If a new leaflet map is created, all pending calls are removed. (#771)

v2.0.4.1

leaflet 2.0.4.1

Features

• Updated proj4.js to 2.6.2

Bug fixes and improvements

• Minor tweaks to example data and tests, required to stay on CRAN

• Fixes broken URL (#742) and updated examples to run from system files (#576) including updated .Rmd and .html docs.

v2.0.3

leaflet 2.0.3

BREAKING CHANGES

• data("providers") and data("providers.details") no longer exist. Please use leaflet::providers and leaflet::providers.details. (#636)

BUG FIXES and IMPROVEMENTS

• Integrated data from leaflet.providers package. See leaflet.providers for details. (#636)
• Fixed rstudio/crosstalk#58, which caused Leaflet maps that used Crosstalk shared data in Shiny apps, to be redrawn at incorrect times.
• invokeRemote() now resolves html dependencies before passing them to shiny::createWebDependency() (#620).
• Upgrade leaflet-provider to 1.4.0, enable more map variants such as CartoDB.Voyager (#567)
• sf objects with names attributes in the st_geometry now visualise correctly (#595)
• GeoJSON objects missing properties can now be displayed (#622)

v2.0.1

Features

• Added method addMapPane to add custom pane layers to have fine tune control over layer ordering. New feature from within leaflet.js v1.x. (#549)
• Exposed htmlwidgets sizingPolicy in leaflet() (#548)

Bug Fixes and Improvements

• Default marker icon locations will now use unpkg.com instead of the leaflet cdn when using https or file protocols. (#544)
• .leaflet-map-pane z-index switched to 'auto'. Allows for map panes to appear above the map if they appear later in the dom. (#537)
• Use correct Leaflet.js scale control remove method. (#547)
• Start from world view if using flyTo or flyToBounds. (#552)
