March 30, 2009
- A new section on making a transit feed publicly available. This wasn't previously discussed on the group, because it wasn't strictly a change to how the data is interpreted or written. However, some of the folks at Google thought that it would be informative to include discussion of non-Google uses of GTFS, since there are an increasing number of applications that can make use of GTFS-formatted data.
- CSV format clarifications: discussion.
- Additional guidance on how to pick contrasting colors in the descriptions of the route_color and route_text_color fields.
- trip_short_name, as proposed and tested in these threads: a and b.
- A fix for a minor error in the sample data included at the end of the document (giving stop S7 the parent_station S8).
- Added "agency_lang" information to the sample data at the end of the document, as suggested by Marcy during the comment period: discussion.
- Updated the link to OCTA's GTFS feed in the sidebar
- See original summary.

- Added 6 (Gondola) and 7 (Funicular) as valid route_type values.

Now stop locations must be given using stop_lat for latitude and stop_lon for longitude, which are more useful for most applications.
