See [Sustained Use Gas Discounts](/developer/deployment-and-production/sustained-use-gas-discounts.md). * **Blake2f fix:** corrects an edge case in the Blake2f precompile * **`GASPRICE` semantics:** the `GASPRICE` opcode (`tx.gasprice`) now returns the price actually charged for the transaction - the sender's discounted base price plus their priority fee - rather than the block's base gas price. This applies to all transactions, calls and simulations, and makes `GASPRICE` sender-dependent. Contracts that use `tx.gasprice` for gas reimbursement or fee floors should review that logic. * **Block history:** gas limits reported for historical blocks are now capped consistently This release also improves RPC compatibility, consensus performance and stability: * \#1762 Implement eth\_sendRawTransactionSync * \#1751 Add accessList field in RPC responses * \#1734 Add `removed` field to eth\_getLogs log objects * \#1765 Harden RPC storage key-type validation * \#1742 Aggregate BLS public keys for message verification * \#1743 #1744 Parallelise and cache the PBFT leader's BLS verifications * \#1737 Parallelise backend validation by transaction * \#1749 Replace validator shards with a single MPMC queue * \#1724 Reduce storage database stalls when pruning * \#1730 Retire obsolete storage data types Reclaiming disk space: After upgrading, node operators can reclaim significant disk space (hundreds of gigabytes on long-running nodes) by deleting the storage data types retired in #1730. With the node **stopped**, run: ```bash somnia delete-obsolete-storage --storage-database-path ``` *** ### somnia-369f69e34c9778c-release - RPC compatibility **Released**: 3rd July 2026 This release is for RPC servers only and fixes compatibility issues: * \#1717 Report gas limits in line with wallets logic (namely Rabby) * \#1721 Better handle bursty loads of historical state requests *** ### somnia-f03d9d276649877-release - Bug fixes and stability {% hint style="info" %} This release matches somnia-e07ba4d147406c9-release on the testnet. {% endhint %} **Released:** 3rd June 2026 Improves system performance and stability, fixes minor bugs: * \#1695 Fix simulation override on an existing contract (eth\_call) * \#1686 Fixes for HSDB rollback * \#1459 Speed up Ice DB compaction * \#1685 Session transaction cancellation and timeout * \#1679 Force PBFT\_PERSISTENT\_STATE pruning * \#1678 Add metrics for reactivity *** ### somnia-f444d2cf8f428d6-release - Hotfix **Released:** 11th May 2026 A hotfix release addressing Cuthbert (shadow verification subsystem) issue that could result in false positive divergence when malicious transaction is executed. *** ### somnia-f6e406d2fb3ef90-release - Hotfix **Released:** 22nd April 2026 A hotfix release addressing RPC issues discovered after the Ingot hard fork. *** ### somnia-c1a0de06c6bcdae-release - Ingot Hard Fork **Activated:** 15th April 2026, 11:30 AM UTC The Ingot hard fork is a major network upgrade that introduces: * **Reactivity:** enables on-chain events * **Session transactions:** allows users to pre-authorize a sequence of transactions, reducing friction for interactive applications * **EIP-7702:** a standard that lets regular accounts temporarily act like smart contracts, enabling more flexible transaction flows * **Agentic L1:** expands Somnia to become a hyper-performant L1 for agents and applications *** ### somnia-0e939b9869cab33-release - Hotfix **Released:** 13th January 2026 A hotfix release addressing storage issues and improving storage efficency. *** ### somnia-3e094e96eab9d76-release - Genesis **Launched:** 1st September 2025 The first mainnet release of the Somnia blockchain - an ultra-high-speed EVM-compatible L1 built for scale. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.somnia.network/developer/network-info/somnia-mainnet-releases.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
