# Incubator PMC report for August 2022

The Apache Incubator is the entry path into the ASF for projects and 
codebases wishing to become part of the Foundation's efforts.
There are presently 34 podlings incubating. Podlings made 5 distinct 
releases. ShenYu graduated last month, Crail has retired, and HiveMall is 
still deciding on retirement. This month we were missing reports from 
Annotator, DataLab, EventMesh, Flagon, Livy, Marvin-AI, Milagro, PageSpeed, 
Pegasus, PonyMail, Sedona, Spot, Teaclave, Toree and Training. All will be 
asked to report next month.
We are currently having an issue with podlings submitting reports and 
getting mentor signoff, even when podlings have been reminded or noted as 
needed to report in previous reports. This points to a lack of PPMC and 
mentor engagement. Some podlings are having issues finalising retiring, and 
some have very low activity. The IPMC will discuss what to do.
There was one IP clearance in July.
Some Podlings shared their stories and the Apache experience at ApacheCon 
Asia.
Most discussions on the mailing list were around releases.
