Offline Mode for the Parca Agent
Collect and upload profiles -- even without a network connection
We're excited to share that the Parca Agent now works offline! Store CPU profiles locally when disconnected, upload when ready. Because not all computing happens in data centers.

If you are using AWS S3 SDK for Rust on Graviton, you should enable the 'asm' feature on the sha2 lib transitive dep explicitly. Otherwise, it will not end up using hardware acceleration. Huge CPU drop for one of our services. Identified this issue using @polarsignals.com
