ChainSafe/forest v0.38.0

v0.38.0 "Ayanant"

on GitHub

Mandatory release for mainnet node operators. It includes support for the NV29 Solstice network upgrade for mainnet, which is set to activate at epoch 6470279 (2026-10-19T12:59:30Z).

For RPC providers

• JSON-RPC batches are now limited to 100 requests by default. Larger batches are rejected with error -32010. If your clients send bigger batches, raise the limit with FOREST_RPC_MAX_BATCH_LEN.
• Size the RPC caches for your traffic. The defaults suit a general node. If you serve trace methods or clients that walk block ranges, the defaults evict cache entries before they are reused, and every miss re-executes a tipset or rebuilds a block. The RPC fine-tuning guide says which setting to raise for which traffic, what each costs in memory, and which metrics confirm the effect.
