google-cloud-python vs. Google
Per-engineer ETV for google-cloud-python against Google as a whole. Both lines are 90-day rolling averages scaled to a 30-day month, so they share one axis and can be read against each other at any point. Pick a window to zoom the chart to it.
Performance over time
ETV stacked by Features / Maintenance / Tests / Docs / Fixes — 90-day moving average, normalized to ETV / month.
Engineering capacity
Effective engineers behind google-cloud-python, in pre-AI terms. Per-engineer ETV divided by the Q1 2025 baseline of 0.86 ETV / dev / mo gives a capacity multiple, and that multiple applied to the engineers active in the trailing 90 days turns it into engineer-equivalents. The line is the real headcount, so the gap between line and area is what the leverage is worth.
Knowledge concentration
How dependent is this repo on a small number of engineers? Higher top-1 share = higher key-person risk.

- 20.6ETVchore: update librarian & regenerate (#17705) Updates librarian version to v0.26.0. This includes a gapic-generator update to v1.36.0 resulting in the attached changes, which can be found in the [second commit](https://github.com/googleapis/google-cloud-python/commit/e20a32e72ffece0ec7e9d3e358205230303800f0). Changes to the bigquery and datastore postprocessing scripts were necessary due to the removal of mypy.ini. These can be found in the [first commit](https://github.com/googleapis/google-cloud-python/commit/8f7111a2c498965aec62c59c8007b90ee6252764).
