- Issues with Jenkins machines because Rust builds run out of memory—workaround increased build time but is a temporary solution

- 5 additional objects need to be added.
- Working on the HIPE for the new Schema object.
- Warnings from rust cargo clippy (Mike and Axel)
- New design for revocation / Anoncreds 2.0 (Mike)

Other Business
- PostgreSQL leaving experimental status (see previous discussion)
- Would like to update existing issues first.
- Ian will be going on vacation.
- Kiva is interested in helping.
- Want to see this happen this year, but maybe wait for the Aries Wallet repo? (Kiva prefers to do it in Aries.)
- Maintainership requirements for Indy Node and Indy SDK
- Don't worry about new maintainers for Indy SDK now, wait for Aries decisions.
- Need for cross organizational review.
- Should define the process, including how we handle exceptions (emergency fixes shouldn't be blocked, but would require notification)
- After PBFT view change (middle of October).
- Ken and Cam can do the reviews of Evernym work.
- For now, Alex will continue reviewing everything.
- Alex should train other reviewers on how to do good reviews.
- How long should we maintain Indy SDK after we start work on Aries core libraries?
- Will need to understand the Aries plan first.
- Partially completed refactoring of the Request format: INDY-1375 and IS-567
- New pack / unpack requires disclosure of recipient
- Cannot hide the receiver of the message like we could with msg_pack
- Allows having multiple recipients of the same message
- Should list the drawback in the Aries-RFC? Is there an alternative way that preserves the capability to selectively disclose the recipient?
- From Kyle Den Hartog
msg_pack presents problems when dealing with an agent that maintains more than one relationship. For example, if I receive a message, I don't know which key in my agent I should be using to decrypt the message. We can get sender anonymity or receiver anonymity, but I don't believe it's possible to get both and still determine who the message is for. - Pack/unpack only exposes the Verkey of the recipients. It does not do forward secrecy.
Future Calls
- Define pull request review process for Indy Node.
- Should define the process, including how we handle exceptions (emergency fixes shouldn't be blocked, but would require notification)
- What is important in a good review?
- Fully Qualified DID support in Indy SDK
- fuzzing libindy https://github.com/AxelNennker/indy-sdk/tree/fuzzing/
`cargo +nightly fuzz run fuzz_target_1 -- -only_ascii=1`
Worried about unsafe code in libindy
```

``` - Ursa and AMCL: Discussed in the Ursa call (August 21), but no decision yet.
- Architecture questions for Indy SDK:
- How to handle old pull requests that failed DCO Checks? Close?
- How to handle pull requests for IOS / Swift wrappers? Close and encourage the move to Aries?
- How to handle pull requests for LibVCX? Deprecate?
- Close PR https://github.com/hyperledger/indy-sdk/pull/1048 as something that will be replaced by the advanced schema work?
