attr_acodes output for some OCDE 'Drive-in' and 'Math/Physics' geocaches Added the has_ratings field to services/apisrv/installation, and removed the services/caches/capabilities method (why?). This method was not in use yet by any application. Changed the <time> field of geocaches in GPX files from listing date to hide/event date, consistent with GC and native OC GPX. Added options to geocache and log retrieval methods, which allow to choose the subfields of owner and user fields. The geocaches' alt_wpts field now includes OCPL hidden-coordinate waypoints. These waypoints are returned with location "0|0". Developers are recommended to hide those null coordinates or show a placeholder like "---". Geocaches' alt_wpts field now better responds to the langpref option.

Added new fields country2 and region to services/caches/geocache. They replace the country and state fields, which have been deprecated due to some issues (see the method docs).

Also added formal (not geographical!) verification of country and region data. For some caches with broken data, an empty country and/or region will now be returned.

 Rewritten the explanations and advice on differences between Opencaching sites. Added the services/caches/capabilities method, and updated the cache types documentation. Added the services/logs/capabilities method. Also added the new fields rcmds_left and rcmd_founds_needed to services/users/user(s). Added the GPX options trackables=gc:travelbugs and alt_wpts=desc:table. Added new fields to replication: short_descriptions, oc_team_annotation, needs_maintenance and watchers for geocaches; images, location, oc_team_entry, needs_maintenance2, listing_is_outdated, date_created and last_modified for log entries. Added the oc_team_annotation option and field to services/caches/geocache(s). OC team annotations now are included by default in cache descriptions. Added the search options recommended_only and recommended_by. Added the watchers, my_rating and is_recommended fields to services/caches/geocache(s). Added the services/logs/edit and services/logs/delete methods. Also OCDE owners are not allowed to not recommend their own caches. Added the status-changing log types Available Ready to search, Temporarily unavailable and Archived to services/logs/submit. (Corrected Available => Ready to search on 2018-11-13.) Added the date_created and last_modified fields to services/logs/entry. The services/users methods will no longer return true for the is_admin field in any case, because OC installations no longer provide a singular admin flag. Do not mangle protocol-relative links in cache descriptions and logs. Enabled the GPX gc_ocde:attrs option for all OC installations. The pseudo-GS IDs of OC specific attributes now are also requestable via the services/attrs methods. Added French translation for OKAPI user messages. services/logs/submit now rejects 'Attended' logs that are earlier than the event date. Added the user_logs_only option the geocache retrieval methods, and corresponding latest_logs=user option to the GPX download methods. Added fields parameter to services/logs/userlogs. Added the Opencaching GPX extension. Use ns_oc=true in services/caches/formatters/gpx (or /ggz) to enable it. OKAPI can now be deployed via PHP composer to OC sites. See the OCDE repository for a sample implementation. services/logs/images/add now returns the URL of the added image. Added services/caches/edit for changing geocaches' log passwords. Added location field to services/logs/entry. Submitting OCPL event cache logs now exactly behaves like the native log functions. Added options date_created and date_hidden to the services/caches/search order_by parameter. The scheme for the installation URLs of several Opencaching sites has changed from http to https. Added advice on the length of saved personal notes. Documentation tags OCPL and OCDE have been added, informing about different behaviour of OKAPI methods on the two Opencaching code branches. Found geocaches are now marked properly in services/caches/formatters/garmin method. Added the log_uuids return field to services/logs/submit. Some OKAPI installation can be accessed through multiple URLs. The new services/apisrv/installation field okapi_base_urls tells you which URLs are available for this installation. Added the Changelog page. The is_admin flag for users has been deprecated. Improved submitting HTML log entries. The comment_format parameter of services/logs/submit now works consistent and deterministic on all OC sites. New methods for adding, editing and deleting log images. Consumer keys may be revoked by OC site admins. services/oauth/authorize will no longer delete Opencaching.DE cookies when called with parameter interactivity=confirm_user. OCDE geocache log entries with and without time are more reasonably ordered. Developers are recommended to keep the order as returned by OKAPI instead of ordering by the log date. The registration date of users can be retrieved. Added the 'needs maintenance' flag to log entries and geocaches. The needs_maintenance option of services/logs/submit has been deprecated; use needs_maintenance2 instead. Added Romanian translation. For caches with the mark 'listing is outdated' (available only on some OC sites), a corresponding message is prepended to the description field. DO NOT rely on this message being there or having a certain content. It may change in the future. The home location of users can be queried, if given in the user's profile (requires OAuth level 3). The URL of the OC site's registration page can be retrieved via apisrv/installation. Restored the OpenCaching.com namespace definition for GPX. Added an advice to the documentation on how to submit log entries without time. Allowed to search for multiple users that (not) found a geocache. Improved posting plaintext logs on OCPL sites. Enabled full 21-bit Unicode for submitting logs on some OC sites. Solved rare problem when searching by distance or bbox (OKAPI crashed). Added the new ignored_status search option which allows to search for caches ignored by the user. This replaces the exclude_ignored option, which has been deprecated. There is a new Opencaching.FR website, which is a local view of Opencaching.DE. Use www.opencaching.de/okapi to access it. Quicker refreshing of map tiles after geocache name changes. Return an HTTP 400 when "negative" dates are passed to services/logs/submit. Improved uuid creation for submitted logs. services/caches/map/tile now is available to chosen consumers (closed BETA). Pipe chars (|) in user names are treated as errors. The user's last-login date on the OC site is updated when running OAuth level 3 methods. The OKAPI code repository has moved from Google Code to Github. When quering the is_watched state of a geocache or searching for watched caches, indirect watches via geocache lists are included. (Geocache lists so far are available only at OCDE and cannot be directly accessed via OKAPI.) Opencaching.org.UK has been removed from the list of OKAPI installations, because it is too outdated. The new powertrail_only option allows to search for caches that are part of a powertrail (on some OC sites). This is a BETA feature, i.e. it may be changed or removed. Updated the Introduction page, with additional advices on backward compatibility. Interprete intervals of services/caches/search/bbox as greater-side-open instead of closed. Added missing oauth_token parameter to error redirect. Added "stealth required" attribute (A74). Corrected the attribute assignments of OC.NL 'lost place' (A30 -> A29) and geodetic point (A2). OKAPI has been deployed to Opencaching.RO.
