<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a>: Company that was sponsoring to work on the team has pulled out; as of January 31, will not be sponsored. Will be around but won’t have much time to commit to this project. Focusing on the tickets listed below. These are all around adding/using caches in core functions and will have a large impact, especially for big sites. Hoping to get some across the line before February.
