# 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. The ShenYu graduated last month, Crail has retired, and HiveMall is 
still in the thread for the retirement vote.

There was one IP clearance in July.

Successfully ApacheCon Asia, IPMC, and some Podlings shared their stories with the Incubator and the Apache experience.

Most discussions on the mailing list were around releases.

## PageSpeed

             PageSpeed represents a series of open source technologies to
help make the             web faster by rewriting web pages to reduce
latency and bandwidth.

### Three most important unfinished issues to address before graduating:

  1.
  2.
  3.

### Are there any issues that the IPMC or ASF Board need to be aware of?
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.
