Solidity Developer Survey 2023 Results
Posted by Vishwa Mehta on April 3, 2024
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...

Posted by Solidity Team on March 14, 2024
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...
Read moreTransient Storage Opcodes in Solidity 0.8.24
Posted by Solidity Team on January 26, 2024
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...

Posted by Solidity Team on January 26, 2024
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...

Read moreBug in Deduplication of Verbatim Blocks
Posted by Solidity Team on November 8, 2023
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...

Posted by Solidity Team on November 8, 2023
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,...

Posted by Solidity Team on October 25, 2023
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...
