We have a few upgrades and bugfixes to announce this month:

• Streamlined transit mode selector and support for extended GTFS route_type values (👋 🚝 🚎).
• Re-enabled JSON download of the scenario used in a regional analysis.
• Clearer errors when attempting to analyze a deleted project, scenario, or bundle, and better logical checks to prevent this error in the first place.
• Cleaner directional markers along modification alignments.

We're excited to announce these updates in the Conveyal platform and routing engine v6.5. This release makes it easier to:

• Group modifications into different combinations, using a new scenario table:

• Create aggregation areas with better progress reporting and validation, using the new Data Sources panel. In an upcoming release, this panel will also handle spatial datasets for custom origins, destinations, and modifications.
• Save and Undo changes to modifications.
• Inspect travel times to specific destinations, with the improved destination marker (click in the travel time legend)
• Avoid certain timing errors on connections experiencing high latency to our central servers.

The latest Conveyal user interface, along with new routing engine v6.4, includes:

• Detailed status and validation messages for GTFS and OSM upload
• Reduced computation time for large regional analyses with complex transit patterns
• Better handling of trips on the same route scheduled to overtake each other
• Clearer presentation of accessibility results
• The latest LEHD/LODES block-level employment release (2018, available via one-click import for US regions)
