raydium-idl's LaunchLab IDL fixes quote_token_program to SPL Token, but live swaps pass Token-2022. It also lacks 7 instructions that the deployed program has, such as update_platform_curve_rule.
The on-chain IDL has neither problem.

Alpenglow hits mainnet ~Oct 21.
Old Faithful added 2 fields per block:
- block markers (footer, header, parent update, genesis cert)
- block id, the hash validators vote on
Jetstreamer 0.8.1 skips both. No error.

It’s time.
Alpenglow goes live on mainnet-beta Wednesday, October 21, ~14:50 UTC.
18 months of work for a migration that happens in one slot. Finality drops from seconds to ~150ms.
Make sure to follow us @anza_xyz as we countdown to go-live.
Details: anza.xyz/alpenglow

Alpenglow is live on devnet 🏔️
A slot can now have two banks index by slot and mix them freely.
Shipstern PR #345 keeps only the confirmed one. → 369/369 devnet slots correct → both banks tested on replayed mainnet slots

Solana 4.2 + V1 is coming to the stack. 👀🚀 Stay tuned!
Shipstern now handles V1 without changing the Legacy/V0 paths.
Legacy → unchanged
V0 → unchanged + ALT
V1 → config preserved
Message.config was the easiest thing to accidentally lose.
Devnet V1 txs now go through Jetstreamer’s wincode decode path, including txs >1232 bytes.
Thanks to @Sam0xSol and @espicodes
Shipstern 0.9.0 is out.
Live filter updates on the Yellowstone gRPC source. Take a RuntimeHandle, patch the filter set with update_filters, the subscription is replaced mid-stream. No reconnect.
Also: Transaction V1 (SIMD-0385) support with the inline compute budget on InstructionShared, Prefilter now covers the full Yellowstone subscription surface (memcmp, datasize, lamports, data slices, accounts_exclude, vote, interslot_updates), DISCRIMINATOR constants on generated types, and CPI event envelopes read straight from the IDL.
Breaking if you match exhaustively on PrefilterError or build prefilters with struct literals. Builder users unaffected.

Last night an infrastructure provider used by some Solana validators had a failure. You probably didn't notice, because the network didn't: blocks kept producing and transactions kept landing.
The facts:
- The Solana network remained operational
- 597 of 699 staked validators kept voting, roughly 6 out of 7
- Affected validators recovered within 40 minutes
- Validators in the Solana Foundation Delegation Program (SFDP) were unaffected
Because Solana validators are distributed across independent infrastructure providers, the failure of a single provider did not interrupt the network. This is decentralization and infrastructure diversity working as intended, and a proof point for Solana’s resiliency though periods of stress.

Make @solana replayable again. 🔴
@Sam0xSol just shipped jetstreamer 0.7.0 work-stealing, a proper TUI, and it finally shrugs off R2’s throttling.
The fun part: yellowstone-vixen wires jetstreamer in as a replay source. Point it at any old mainnet epoch and it streams straight from Old Faithful’s archives. No validator, no RPC quota, no gRPC x-token nothing to spin up.
Best bit is you write your parser once and it doesn’t care if the data’s live or from six months ago. Same Pipeline/Handler API either way.
Give it a look 👇
Jetstreamer 0.7.0 is now live, featuring:
- a TUI for visualizing progress 📈
- support for OF's new slot index format 📋
- thread work-stealing 🔥
- several performance and behavior fixes ⚡️
- resistance to R2's recent throttling changes 🕵️♂️

Size prefix was only a modifier, so you couldn’t nest it. it’s a type node now, like fixed size already is:
option(size_prefix(string, number(u8)))
the prefix can go positional or named. size prefix isn’t a special case anymore.
tldr: one piece of code can now be reused in more

Found this reviewing my own PR to rpcpool’s yellowstone-vixen:
On SIGTERM the indexer bailed instantly instead of waiting for in-flight handlers. The tokio runtime dropped them mid-await right in the middle of a DB write.
before → exit 0.03s 6983 started 6982 finished ✗ 1 truncated
after → exit 0.54s 11843 started 11843 finished ✓ zero lost
8-line fix. And yeah I checked the regression test actually fails without it.
