Here’s what’s changed in version 26.5.1

In HCM’s second update of May 2026, we’ve given Mission Analysis a big upgrade, improved the efficiency of fetching flights, rostered duties and recalculating Qualification Groups and addressed various reported issues.

What’s new?

1. Mission Analysis gets a boost of features, speed and usability & adds handy shortcuts - the Mission Analysis tool now acts a more comprehensive flight lookup, allowing you to filter by all of flight properties, pilots and more as well as existing Mission Data - which now renders options in a smarter way based on your Mission Definitions. Flights will now load 50-70% faster, as well as giving you the option to jump directly to the flight itself if you need to make edits.
2. Load your roster more efficiently and much faster - the roster itself will now fetch duties faster based on your selected User Groups, and unload deselected groups in the Pivot View to save memory and increase performance.
3. Mission photos & CofG changes - this moves photos out of the Mission Analysis results and into the individual flight pages, and makes sure to only render CofG data when there is associated information to fetch.

What’s fixed?

1. Redundant recencies are now automatically purged - when making changes to a flight’s registration or other properties, the dynamic recencies that can be edited now flush out old entries to prevent false histories.

We also tweaked:

1. The “Duty Code” Pivot View in the Roster now displays up to two User Codes, with the ability to expand the list to see all visible crew members - improving performance when loaded in.
2. Lifetime checks will now match the behaviour of standard checks when they are awaiting approval by OPS.
3. Updated support email to “support@quantavia.net” when encountering errors.
4. Recalculating Qualifcation Groups when changes are made is now more efficient.
5. Fixed a problem where users could not resubmit a check revalidation when a submission had been rejected earlier that same day.
6. Fixed a problem where a rejected/deleted expiry date would appear when revalidating a check.
7. Fixed an issue where alerts would sometimes appear underneath other elements on the page.
8. Removed the Heatmap Generator function as the underlying library became deprecated.
