Marinade Borrow is live.
Borrow USDC or SOL against your staked SOL. Stake accounts work, and so do mSOL and SOL in your wallet. Everything keeps earning while it backs the loan.

My machine kept freezing when I used async-profile.
This is the deepest I've ever gone: debugging a Linux kernel deadlock, performing live surgery on a frozen CPU with GDB, and pulling off a questionable resurrection.

📝 I have a write-up about working with @solana @anchorlang programs from different versions

@solana_devs
I just found that the anchor-gen @anchorlang Rust library for IDL handling and managing compatibility with older Anchor versions was updated a few months ago to support the latest Anchor version. Nice.
