Many times it would have been advantageous to be able to query a running node and retrieve some diagnostic data about it. To this end we should add APIs for querying the following data from the debug-endpoint:

Per stackoverflow post https://stackoverflow.com/questions/69115892/hyperledger-fabric-java-chaincode-timeout-expired-while-starting-chaincode , it appears Java chaincode is missing from chaincode as an external service doc topic:

Looking at the list of Yul transformations in the documentation, I noticed a few slight differences between the list at https://docs.soliditylang.org/en/latest/yul.html#optimization-step-sequence and the list at https://docs.soliditylang.org/en/latest/internals/optimizer.html#optimizer-steps:

Issue
The "Full Example" of using @truffle/contract to interact with contracts should include an example of listening to an event with a filter.
In the past, it used to be possible to pass a filter object on indexed event parameters when listening to an event, as seen for example [here](https://ethereum.

Background
Macaroons are created after wallet creation. However, the documentation in the main installation (https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md) states the following:

Problem
Solana CLI tools display user controlled input from various sources without any sanitization. A malicious user can craft input to include ANSI escape sequences, hijacking a victim's console and spoofing legitimate command output. Naturally leading to social attacks
Some affected sources of user-controlled text input
- Memo instructions
- Program logs
- Validator info
