CLI extension management

We've added explicit install and update commands to the Goldsky CLI for extensions like Compose. You can now run goldsky compose install to set up the extension, or goldsky compose update to grab the latest version—including support for pinning specific versions with --version 0.2.0.

This also fixes a longstanding bug where goldsky compose --version would show the help menu instead of the version number. Small fix, big annoyance gone.

Stellar Ledgers 1.2.0 with XDR support

Mirror now supports Stellar ledger data via XDR sources. You can stream Stellar mainnet ledgers directly into your pipeline with the new stellar_mainnet.ledgers dataset—complete with all the transforms from v1.1.0 baked in. Just point to the dataset, set your block range, and go.

If you're building on Stellar, this makes indexing ledger data significantly cleaner.

Address checksum function

We've rolled out a new to_checksum_address function for transforms. It handles EIP-55 and EIP-1191 checksumming of hex addresses, so you can normalize addresses without external tooling. Works exactly how you'd expect—pass in a hex address, get back the properly checksummed version.

Compose concurrent execution fix

We tracked down a subtle but painful bug where Compose tasks would hang indefinitely when running concurrent context function calls (like multiple fetch or readContract calls with identical parameters). The root cause was deterministic IPC message ID generation that caused collisions under concurrent load.

This affected pipelines with parallel operations—particularly oracle feeds and multi-contract reads. Tasks that previously hung for 30 minutes until timeout will now complete normally. If you've been seeing mysterious hangs in Compose, this is the fix.
