<p class="MsoNormal"><span style="font-size:11pt">I had the pleasure of helping review issues/PRs for Kata this week as part of the review rotation. Here are some highlights from the project over the past week:<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11pt">identified that our burn-rate for CI resources has been increasing with the number of jobs and length of PR based CI jobs. This motivated several of us to stop and look at improvments that could be done. Initial
changes include utilizing smaller container images for basic tests and reducing duplicated tests across various jobs. We plan to make further improvements by predicating larger test jobs by a passing static-check (ie, proper utilization of a pipeline), and
better utilizing filters to not require full CI for non-code changes.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>

<p class="MsoNormal"><span style="font-size:11pt">There are several outstanding PRs which could use help moving forward, and I marked these with the label `needs-help`. If any sound interesting, please jump in! Examples include:<u></u><u></u></span></p>

<p class="MsoNormal"><span style="font-size:11pt">creating sizing annotations for Kata, and creating an example k8s admission controller which would set kata annotations in the PodSpec, which Kata would then consume. The initial PR has some suggestions on
how to do this in a generic way, but is starting to go stale. We'd love to have help here. See
