0.1.4

Major changes:

New osm_enclosing() function; thanks to @barryrowlingson via #199
opq() now has additional datetime and datetime2 parameters which can be used to extract historical data prior to datetime, or differences between two datetimes by specifying datetime2; thanks to @neogeomat for the idea in issue#179. # opq() also has additional nodes_only parameter to return nodes as points only, for efficient extraction of strictly point-based OSM data; thanks to @gdkrmr for the idea in issue#221.

Minor changes:

New contributor Enrico Spinielli (@espinielli), via #207, #210, #211, #212 - Thanks!

0.1.3

Major changes:

osmdata_pbf function removed as the overpass server no longer provides the experimental API for pbf-format data.
Remove deprecated add_feature() function; entirely replaced by add_osm_feature().
get_bb() with polygon output formats now returns ALL polygon and multipolygon objects by default (issue#195)

Minor changes:

Major changes:

New function unname_osmdata_sf, to remove row names from sf-format geometry objects that may cause issues with some plotting routines such as leaflet.

Minor changes:

getbb now allows arbitrary featuretype specification, no longer just those pertaining to settlement forms.
available_tags returns tags with underscore precisely as required for add_osm_feature - previous version returned text values with spaces instead of underscore.
Fix bug in osmdata_sf for data with no names and/or no key-val pairs
Fix bug in trim_osmdata for multi* objects; thanks to @stragu
Implement trim_osmdata.sc method
retry httr calls to nominatim, which has lately been timing out quite often

Minor changes:

Major changes:

New function, osm_elevation to insert elevation data into SC-format data returned by osmdata_sc function.
New vignette on osmdata_sc function and elevation data.
opq() function now accepts polygonal bounding boxes generated with getbb(..., format_out = "polygon").

Minor changes:

Bug fix for vectorized lists of values in add_osm_feature, so only listed items are returns (see #139; thanks @loreabad6)
But fix to ensure all sf data.frame objects have stringsAsFactors = FALSE

Major changes:

New function osmdata_sc to return data in silicate::SC format (see github.com/hypertidy/silicate; this also requires additional dependency on tibble)
Structure of osmdata object modified to replace former $timestamp field with $meta field containing a list of $timestamp, $OSM_version (currently 0.6), and $overpass_version.
add_osm_feature() now accepts vectors of multiple values (see #139).
osmdata_sf() objects default to character vectors, not factors (see #44).

Minor changes:

vignette updated
Overpass URL now randomly selected from the four primary servers (see https://wiki.openstreetmap.org/wiki/Overpass_API#Public_Overpass_API_instances), thanks to @JimShady.
bug fix for osmdata_sp() (see #56)
osmdata_sp() fixed to return osm_id values (see #131; thanks @JimShady).

Fix bug in trim_osmdata so that all sf attributes are reinstated, and also issue message that sf-preload is necessary for this function
Fix bug with opq (key_exact = FALSE) so value_exact is always also set to FALSE

Add new function ‘osm_poly2line()’ to coerce the ‘osmdata$odm_polygons' object for 'osmdata_sf' objects to lines, and append to 'osmdata$osm_lnes’. This is important for street networks (‘add_osm_objects (key = “highway”)’), which are otherwise separated between these two components.
Add new function opq_osm_id to query by OSM identifier alone
Add timeout and memsize options to opq() to improve handling large queries.
Return useful information from overpass server when it returns neither error nor useful data
Make C++ code interruptible so long processing can be cancelled
Fix minor yet important C++ code lines that prevented package being used as dependency by other packages on some systems

Add extraction of bounding polygons with getbb (..., format_out = "polygon")
Add trim_osmdata function to trim an osmdata object to within a bounding polygon (thanks @sytpp)
Add unique_osmdata function which reduces each component of an osmdata object only to unique elements (so $osm_points, for example, only contains points that are not represented in other - line, polygon, whatever - objects).
Rename add_feature to add_osm_feature (and deprecate old version)

Enable alternative overpass API services through get_overpass_url() and set_overpass_url() functions
Extend and improve vignette
