# Chainstack updates: September 2, 2026

> Starknet nodes are upgrading to Pathfinder v0.24.0, adding Starknet 0.14.4 support. WebSocket clients need no changes.

**Starknet**. Chainstack is upgrading Starknet nodes to [Pathfinder v0.24.0](https://github.com/equilibriumco/pathfinder/releases/tag/v0.24.0), which adds support for Starknet 0.14.4.

Pathfinder 0.24.0 upstream requires WebSocket clients to answer server-initiated pings. **On Chainstack this needs no action from you.** Your endpoint keeps the WebSocket connection alive on your behalf, so the upstream change does not reach your client and your existing subscriptions are unaffected.

One behavior change does reach you: the fallback path that `starknet_traceTransaction` and `starknet_traceBlockTransactions` use when a trace is not available locally is now bounded at 30 seconds. A trace request that previously waited on a slow sequencer now returns within that ceiling instead.

The JSON-RPC API versions served do not change — 0.9 on `/rpc/v0_9` and the default path, 0.10 on `/rpc/v0_10` — and no RPC methods are added or removed.
