Changelog February 2025

Improvements

  • We've implemented some technical improvements that have made the overall platform faster, resulting in quicker page load times.
Bug fixes
  • Our URLs tried something new by merging work categories. We gave them commas, so they are separated correctly again.
  • We fixed the problem where reminder emails for multiple work categories within a project contained incorrect links.
  • Messages sometimes ended up in the wrong project. We have ensured that they now end up in the correct place.
  • The work category filter in Publications was taking a little too much charge and overwriting other active filters. Now you can filter as you should again!
  • We fixed a bug in Publications that sometimes caused a message to be sent to a large number of subcontractors. Now no more email spam, unless you really like to keep sending the same message.
