Solidity is evolving rapidly

We aim for a regular (non-breaking) release every month, with approximately one breaking release per year. You can follow the implementation status of new features in the Solidity GitHub project.

Get started

Contribute to Solidity

Solidity continues to improve with help from our global community. Check out these ways to get involved and contribute to the Solidity project.

Reporting issues and vulnerabilities

To report an issue, please use the GitHub issues tracker. To report a vulnerability, please check out the instructions in the SECURITY.md.

Translating the documentation

Translations help developers from all corners of the world to be able to read the documentation and learn Solidity.

Fixing and responding to issues

Fixing and responding to issues, especially those tagged as “good first issue”, is a great way to get started for external contributors.

Contributing to language design

We welcome Solidity power users, auditors, security experts and tooling developers to get involved in the Solidity language design process. Join the Solidity forum, where existing properties of the language and proposals for new language features can be discussed.

Stay Updated

Stay always up-to-date by following the Solidity blog.

You can see the upcoming changes for the next breaking release by switching from the default branch (develop) to the breaking branch. You can actively shape Solidity by providing your input and participating in the language design in the Solidity forumand participating in the yearly Solidity developer surveys.

Bug 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...
