Known Issues with 1.2.23

• The new terrain rendering feature in aven is still somewhat experimental, and has a few known limitations:
  • #56 The altitude of the terrain and altitudes from GPS fixes don't match (typically off by a few 10s of metres)
• If you're using Therion with Survex 1.2.23 on Microsoft Windows, Therion will fail to run cavern. The proper fix is to Therion, but Survex 1.2.24 includes a workaround for the issue.
