  11    - **General Code Housekeeping**: Ongoing code optimizations and bug fixes.
  12    - **Trending and release testing**: Ndrpdr tests use newer code

  17    - [Performance dashboard](https://csit.fd.io/) got updated with the
  18      possibility to [search in tests](https://csit.fd.io/search/).
  19    - [Per Release Performance Comparisons](https://csit.fd.io/comparisons/) got
  20      updated with the function removing extreme outliers from data presented in
  21      the comparison table.

  23 # Known Issues
  24
  25 These are issues that cause test failures or otherwise limit usefulness of CSIT
  26 testing.

  28 ## New
  29
  30 Any issue listed here may have been present also in a previous release,
  31 but was not detected/recognized/reported enough back then.

  53 # Root Cause Analysis for Regressions
  54
  55 List of RCAs in CSIT 24.02 for VPP performance regressions.
  56 Not listing differences caused by known issues (uneven worker load
  57 due to randomized RSS or other per-worker issues).
  58 Also not listing tests which historically show large performance variance.
  59
  60 Contrary to issues, these genuine regressions do not limit usefulness
  61 of CSIT testing. So even if they are not fixed
  62 (e.g. when the regression is an expected consequence of added functionality),
  63 they will not be re-listed in the next release report.
