Most notable changes in this breaking release: Arithmetic operations are checked by default, the ABI coder v2 is activated by default, internal errors like division by zero, assertion failure and others do not use the invalid opcode anymore, but use revert with a special error message.
For all details please refer to the announcement post and check out the new release here.
As a relatively young language, Solidity is advancing at a rapid speed. We aim for a regular (non-breaking) release every 2-3 weeks, with approximately two breaking releases per year. You can follow the implementation status of new features in the Solidity Github project. 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.

The winners of this year's Solidity Underhanded Contest have been selected! Read summaries of the winning submissions and more in the winner announcement.
As a beginner, you find great tutorials, resources and tools that help you get started building with Solidity on the ethereum.org developer portal.
Alternatively, you can start by learning the basics about blockchain, smart contracts and the Ethereum Virtual Machine (EVM) in the Solidity docs.
We welcome Solidity power users, auditors, security experts and tooling developers to get involved and actively contribute to the Solidity language design process.
Join the solidity-users forum, where existing properties of the language and proposals for new language features can be discussed.
Give input by completing (feature) feedback surveys which are regularly distributed via Twitter and the solidity-users forum.
Join the dedicated language design discussion calls, in which selected topics, issues or feature implementations are debated in detail.
Or share your thoughts and take part in design discussions directly via relevant Github issues.
For ad-hoc inquiries and questions you can reach out to the core team using the Solidity-dev Gitter channel, a dedicated chatroom for conversations around the Solidity compiler and language development.
The 1st Solidity Summit took place online on April 29-30 2020 and featured discussions & talks on Solidity, Yul, language design and tooling. The event aimed to...
