Release proposal for libdd-telemetry and its dependencies

This PR contains version bumps based on public API changes and commits since last release.

Cut from non-default ref

This proposal was generated from 5ff99ff6c465a95a740a494f42cce258c0e80be8 instead of the default latest origin/main.### Non-default workflow options

bypass_standard_checks was enabled: the ongoing-proposal branch guard was skipped; branches use proposal prefix release-proposal-testing and release prefix release-testing. Crates whose resolved git tag is not the latest SemVer tag for that crate are still included (normally skipped).## libdd-common
Next version: 3.0.1
Semver bump: patch
Tag: libdd-common-v3.0.1

Comparison

Benchmark execution time: 2026-03-25 17:09:21

Comparing candidate commit 11783ad in PR branch release-proposal-testing/libdd-telemetry/20260325-164719 with baseline commit db9b9f4 in branch release-testing/libdd-telemetry/20260325-164719.

Found 5 performance improvements and 12 performance regressions! Performance is the same for 44 metrics, 0 unstable metrics.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

  • 🟩 = significantly better candidate vs. baseline
  • 🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'
