Release v1.16 Issues?

  • The decision is we will be cutting a new tag (1.17alpha) from the main and we will get a review of back ports to be merged either to the next stable release.

:bar_chart: PX4 Docs — Top 10 Most Visited Pages

We’ve been analyzing CloudFront access logs with Athena to understand what pages developers visit most.
Here are the top 10 pages for the main branch (current documentation):

# Page Views Unique Visitors
1 /main/en/ 8,892 6,380
2 /main/en/advanced_config/parameter_reference.html 5,643 2,867
3 /main/en/sim_gazebo_gz/ 4,558 2,627
4 /main/en/simulation/ 3,655 2,370
5 /main/en/ros2/user_guide.html 3,289 2,091
6 /main/zh/ 2,929 2,249
7 /main/en/flight_controller/pixhawk6c.html 2,478 1,820
8 /main/en/flight_controller/cubepilot_cube_orangeplus.html 2,302 1,637
9 /main/en/dev_setup/building_px4.html 2,226 1,628
10 /main/en/flight_controller/pixhawk4.html 2,120 1,450

:puzzle_piece: Highlights

  • The parameter reference and simulation topics remain the top entry points for developers.
  • ROS 2 usage continues to rise in page traffic.
  • The /zh/ section ranks in the top 10, showing steady engagement from the Chinese community.
  • Flight controller hardware pages (Pixhawk 4, 6C, Cube Orange Plus) are consistently among the most visited.

:bar_chart: PX4 Docs — Traffic by Version

Here’s a quick snapshot of documentation traffic by version, based on CloudFront access logs analyzed through Athena.
These numbers reflect total page views and approximate unique visitors.

# Version Views Unique Visitors
1 main 313,370 59,953
2 v1.16 66,129 16,097
3 v1.12 50,121 14,369
4 v1.15 46,518 10,218
5 v1.14 43,222 10,907
6 v1.13 37,317 10,416
7 v1.11 35,615 9,011

:puzzle_piece: Highlights

  • The main branch clearly dominates, accounting for over 60% of total traffic.
  • v1.16 (the latest release) is gaining traction quickly, suggesting good adoption.
  • Older versions (v1.11–v1.15) still see meaningful traffic — strong indicator that long-term users reference older hardware and configurations.
  • The “other” category includes non-versioned or legacy URLs still being accessed, worth reviewing for potential redirects or cleanup.
