Changelog

c3nav does not exactly have a versioning scheme.

This file aims to give you an idea of what has changed between events where c3nav was used or supported by the development team. These lists do not aim to be complete but help you get an overview about the most iportant changes and potential backwards incompatibilities.

Easterhegg 2025 (development ongoing)

Behind the scenes, comfort, bug fixes:

fix bug that prevented the UI from working when no overlays were configured
add instance name to sentry bug reports
avoid excessive number of queries in the theme code during every request
rip out awful old Editor API that hopefully noone ever used
finally tracked down the bug locking the entire map while processupdates was running, meaning you can not continue using the editor while processupdates is running.
better type hinting in some places
fix bug introduced 4 months ago that allowed users with access to the editor to self-review changesets so long if they only created objects within spaces
fix very persistent theme color caching issues

38. Chaos Communication Congress (38c3)

Big stuff:

Quest support to categorize rooms, find AP altitudes, AP names, do wifi scanning and generate route descriptions
data overlay support
complete rewrite of editor changesets as a base for a more modern editor – you will lose all changesets!
new map settings API endpoint
ability to import APs from NOC eventmap
ability to import Antennas from POC
introducing load groups, a way to display how crowded certain parts of the map are based on statistics from WiFi APs
new positioning algorithm based on AP positions, not very good but results look convincing
overlay to show all your own moving positions

Semi-big stuff:

"show nearby" is now clustered for points too close together
Doors now have a UI to easily manage edges that go through them, as well as a To Do feature
space can now be classified as "identifyable" to determine which route descriptions they need
reports for wrong locations can now be auto-rejected based on location g
access restrictions that are part of an access restriction group are now defined in the group, data was migrated
editor access restriction overview now highlights affected spaces on a map
editor access restriction group edit now shows spaces with selected access restrictions and allows selecting through double click
WayTypes can now be excluded by default
Pass route options through url parameter
support for various SSOs
various compliance checkboxes
support for importing projects and rooms from hub
match APs using name broadcast in Aruba vendor-data instead of just BSSIDs
fewer and more performant calls to redis
pruning redis cache automatically after a new map update is created

Small stuff:

Fix bug where it hasn't been possible since ages to link to POIs without a slug
External URLs is now shown more prominently, with a custom label and can now also be set for location groups
Level short_label has been split into short_label (for displaying) and level_index (for internal use like coordinates)
some API mapdata endpoints were moved, some lesser used properties renamed
proper support for access restricted levels
ability to store mutiple BSSIDs per beacon
importhub can now import projects and rooms as well
