We are excited to announce the release of the Solidity Compiler v0.8.26. This newest version of the compiler brings support for custom errors in require, improved default Yul Optimizer sequence that will speed up compilation via IR, several bugfixes, and more! Notable Features Custom errors support in require Custom errors in Solidity provide a convenient and gas-efficient way to explain to the user why an operation failed. Solidity 0.8.26 introduces a highly anticipated feature that enables the usage of errors with require function. The require function...

EDIT REMARK: We noticed a minor error in the graphical representation of [1] popular Ethereum-specific IDEs and [2] Sourcify usage. The results in this blog post and corresponding graphical data in the slide deck has been updated to reflect this rectification that represents the survey data accurately. We are thrilled to share with you the Solidity Developer Survey 2023 results! In this blog post, we will be going over key insights and detailed analysis of the various sections of the survey. Before...

Introducing the newest version of the Solidity Compiler: v0.8.25. This is a minor release following the Dencun hard-fork on Ethereum mainnet that occurred on March 13, 2024 at 13:55 UTC. Dencun Upgrade The Dencun upgrade combines changes to both Ethereum's consensus and execution layers. The full list of protocol changes can be found in EIP-7569. With Dencun now live on mainnet, we are accordingly making cancun the default EVM version the compiler will emit code for. MCOPY in code generator The previous release made the mcopy() builtin...

Solidity 0.8.24 supports the opcodes included in the upcoming Cancun hardfork and, in particular, the transient storage opcodes TSTORE and TLOAD as per EIP-1153. Transient storage is a long-awaited feature on the EVM level that introduces another data location besides memory, storage, calldata (and return-data and code). The new data location behaves as a key-value store similar to storage with the main difference being that data in transient storage is not permanent, but is scoped to the current transaction only, after which...

We are excited to announce the release of the Solidity Compiler v0.8.24. This newest version of the compiler brings readiness for the "Cancun" network upgrade, including support for transient storage (EIP-1153), shard blob transactions (EIP-4844) & more. The release binaries for macOS are now also compatible with Apple silicon chips. Cancun Network Upgrade The "Cancun" network upgrade provides new features in the form of opcodes and precompiles, which will need to be explicitly used to have any benefits, but also introduces changes in the existing...

We can't believe it's already been two weeks since we met in Istanbul, Türkiye, for the third edition of Solidity Summit! Solidity Summit 2023 was part of the Devconnect week and took place on Thursday, November 16, 2023. With roughly 300 participants, the event was well attended. The day was packed with 15+ sessions on: Solidity internals and tips & tricks Solidity tooling Smart contract testing & security best practices EVM Languages and mechanisms ... and more! The full agenda of the day can be found here. You...

On October 24, Ori Pomerantz reported a bug affecting the use of verbatim builtin in Yul code. After investigating, the team was able to confirm the problem and locate its origin. The bug existed in the Block Deduplicator optimizer step, wherein equivalent assembly blocks are identified and merged. verbatim assembly items surrounded by identical opcodes were incorrectly considered identical and unified. The bug existed since version 0.8.5, which introduced verbatim, and only affected pure Yul compilation with optimization enabled. Solidity code or Yul used in inline assembly blocks would...

Today, we announce the release of the Solidity Compiler v0.8.23. This newest version of the compiler is meant to be a pure bugfix release that includes the fix for an important bug of low severity. Based on our investigations, we do not foresee real-world instances of the bug being used as an exploit or an attack vector and thus, we assess its overall severity as low. This version also introduces a small change to optimizer settings to make them more intuitive. Since v0.8.21,...

We are excited to announce the release of the Solidity Compiler v0.8.22. This newest version of the compiler includes a range of language as well as compiler improvements such as file-level event definitions, optimizations for unchecked loop increments, support for importing EVM assembly JSON, & more. Important Note This release deprecates support for EVM versions older than Constantinople, which are becoming increasingly hard to maintain. These ancient versions have long been obsolete on the Ethereum mainnet and testnets and we suspect that they are no...
