v 0.1.1

Major changes:

• Repository moved from "ATFutures/gtfs-router" to "UrbanAnalyst/gtfsrouter"
• gtfs_transfer_table() function now much faster due to re-coding in C++
• Removed previously deprecated gtfs_isochrone() function; now entirely replaced by gtfs_traveltimes().

Minor changes:

• gtfs_timetable() modified to work on feeds which do not have "calendar.txt"
• Fix transfer_times function with updated dodgr match_pts_to_verts fn
• Improve estimation of pedestrian transfer times
• Fix transfer times when GTFS feed extends beyond bounds of provided network
• Bug fix in gtfs_route_headway() function (#94; thanks to @zamirD123)
• Bug fix in gtfs_traveltimes() to remove trips ending at start (#99; thanks to @viajerus)

v 0.0.5

Major changes:

• Add new gtfs_traveltimes function and deprecate gtfs_isochrone

Minor changes:

• All main functions now use a grep_fixed parameter to enable finer control over station name matching; thanks to @polettif via #66 for the idea.
• That also includes a check to ensure matched stations are sufficiently close, which in turn requires geodist to be moved from Suggests to Imports.
• route_pattern arguments (to gtfs_route/isochrone/timetable() functions) can now be used to exclude specified patterns by prefixing them with "!" (see #53)
• The berlin_gtfs_to_zip() function now returns the path to the GTFS zip file it creates.
• Fix bug with max_transfers parameter of gtfs_route() function (see #47)
• Fix bug when column names do not exactly match expected values (#70; thanks to @AlexandraKapp)

v 0.0.4

Major changes:

• New function, gtfs_route_headway to calculate headways for entire routes between any nominated points (see #43)
• Important bug fix that prevents routes including stops that are not part of actual route

v 0.0.3

Major changes:

• New function frequencies_to_stop_times thanks to new co-author @stmarcin, and new contributor @AlexandraKapp
• Data without transfers.txt now load rather than error
• New function gtfs_transfer_table makes transfer table for feeds which contain no such table; see #14
• Main gtfs_route() function now accepts multiple from and to values, and returns a list of routes (see #28).

Minor changes:

• extract_gtfs has new parameter, stn_suffixes, to enable specification of any suffixes to be optionally removed from station IDs (#37; thanks to AlexandraKapp).
• Bug fix in station name matches in gtfs_route fn (see #26)
• gtfs_route accepts stop_id values as well as stop_name (see #26)
• gtfs_isochrone accepts equivalent stop_id values via from_is_id parameter.
• both gtfs_route and gtfs_isochrone accept (lon, lat) values for from and to stations.
• gtfs_isochrone returns stop_id as well as stop_name values (#29).
• gtfs_isochrone returns arrival_time for all mid-points (#30, #36; thanks to @AlexandraKapp)
• Former errors in reading of zip archives on Windows OS fixed
