Scheduled
We will be upgrading our Solana nodes on Solana Mainnet to 1.18.15 on 2024-06-13 at 08:00 UTC.

Please note that there will be no network downtime. However, you may experience the following:
- A minor increase in 503 errors.
- Slight increase in response times and some TCP connection interruptions.

During the initial testing, we detected the following API changes:
- RPC's `simulateTransaction` now returns `innerInstructions` as `json`/`jsonParsed`

We understand the importance of reliability and apologize for any inconvenience this may cause. Our team is working diligently to minimize disruptions and ensure a smooth maintenance process. Thank you for your understanding.
