+--------------------
+
+1) Confirm quorum
+
+Quorum is present.
+
+2) Secretary
+
+Secretary is Andre Pradhana.
+
+3) Forum
+
+Nothing to discuss from the Forum.
+4) TAC Update
+
+a) Emily Ollin wants to setup a process for releasing major versions for all
+   projects. Regarding the 9.1 release, Ken will send an email to the larger
+   OpenVDB ASWF mailing list. Dan will make an announcement on twitter.
+
+b) PyPi We should create our own account. This is what OpenTimeIO has done.
+   We will follow their example.
+
+c) CI Amazon has hardwares that we should be able to use. It is being used by
+   OpenColorIO. The process still works through Github Actions, but the host
+   machines are different. It has to be approved by the ASWF governance board.
+   Once this is approved, we can follow up to change the CI machines.
+
+There is a slack channel hosting this ASWF CI topic.
+
+5) Half
+
+Greg met with an Autodesk representative. Greg's plan is to use half as a
+first-class citizen in OpenVDB and to do computations in floats, but to store
+the results in halfs. He plans half for the OpenVDB 10 release in October.
+
+Autodesk cannot use NanoVDB because they need to perform dilation before
+performing motion blur.
+
+6) OpenVDB Mathematica Link
+
+Greg is optimistic that we can find a working solution to have a Wolfram Engine
+for the purpose of contributing to OpenVDB.
+
+7) VFX Reference Platform
+
+Jeff Lait said that VFX Reference Platform now lists OpenVDB 10, unless we fail
+to release version 10 by October 2022, under the CY2023 draft.
+
+8) ValueIterator on LeafNode
+
+Nick improved the VolumeToMesh tool in OpenVDB by making it up-to-date with
+C++11 and C++14. He also improved the use of Leaf Node Value Iterator by creating
+a new wrapper that pulls the buffer data in order to avoid atomic access with
+delayed-loading. The whole effort makes the tool 10-15% faster.
+
+Nick will do a PR on changing the Leaf Value Iterator of the Leaf Node.
+
+9) Next meeting
+
+Next meeting is on June 28th, 2022. 1pm-2pm EDT (GMT-4).
