Summary

Backport of #651 to the 5.1 docs:

  • A section on upgrade compatibility with pre-4.6 feature logging: feature views that enabled logging before 4.6 keep their pair of logging feature groups, old and current clients keep working against it, and delete_log() converts it to the combined layout.
  • A warning that a deployment still running a pre-4.6 client loses its logs once delete_log() has converted the pair, so its environment should move to a 4.6 or later client first. The 4.4 to 5.0 upgrade test showed this.
  • The delete section states what the transformed argument does on each layout.

This release line has no logging transports, so the text describes the combined layout without them.

Test plan

  • Site not built locally; one Markdown file changed.

Backport of the feature logging user guide changes to this release
line: an upgrade compatibility section for feature views that enabled
logging before 4.6 (the pair of logging groups is kept, old and current
clients keep working against it, delete_log() converts it to the
combined layout), and delete and materialize sections that state what
the transformed argument does on each layout.

The release line has no logging transports, so the text describes the
single combined layout without them. It also warns that a deployment
still running a pre-4.6 client loses its logs once delete_log() has
converted the pair, which the 4.4 to 5.0 upgrade test showed.
