v0.3.1

0.3.1 - Remove potentially sensitive analytics

Commits

Remove potentially sensitive analytics, including path to rerun source code on panics, and rerun branch name when building from source #1563

v0.3.0

After a successful launch a couple of weeks ago, we're back with our second release!
With a few exceptions this release focuses on internal refactors & improving our processes.
However, we think you'll enjoy these goodies that made it in nonetheless!

23-03-02_18.44.38.patched.mp4

You can now generate point clouds directly from depth textures and choose a wide variety of color maps.
Check out this video on how to use it.
This is a lot faster and more convenient than doing so manually in your own code
Some caveats: Picking is not yet working and visible history may behave differently (related to #723)

Other highlights:

• Viewer
  • Improved formatting of date-times in plots #1356
  • Labels for 3D objects have now a color can now be selected & hovered #1438
  • Scale factor is saved across sessions and more persistent between screens #1448
  • Showing tensors in the viewer is now faster
• SDK
  • Python packages now work with Ubuntu-20.04 #1334
  • u8 segmentation stay u8 now (they converted to u16 before) #1376
  • 2D Line strips can now be logged directly #1430
  • Add a strict mode to the Python SDK where misuses of the API result in exceptions being raised.#1477
  • Fix disabling Python API through init not working #1517
• General
  • We build now with fewer build dependencies (there is however still more work to do!).
    Notably, we previously used a version of the time crate which had a security issue (CVE-2020-26235), thanks @mpizenberg for helping out!
  • Print more information & troubleshooting info on crash

Meanwhile, we did a bunch of improvements to our manual. If you had trouble running Rerun so far, check our updated troubleshooting page (and as always, please open an issue if something doesn't work).

⚠️ BREAKING: old .rrd files no longer load ⚠️
