General: Restrict the existing experimental features (generic-solidity, lsp, ethdebu…
We are excited to announce the release of the Solidity Compiler v0.8.34! Changelog Important Bugfixes: Yul IR Code Generation: Fix a bug that could result in clearing a storage variable instead of a transient storage variable at the same position in the layout (and vice-versa). Compiler Features: Yul Optimizer: Remove redundant prerequisite steps from the default optimizer sequence. We would espec…
We are excited to announce the release of the Solidity Compiler v0.8.32! Changelog Important Bugfixes: Code Generator: Fix a bug in clearing/copying of arrays that straddle the end of storage, potentially resulting in assignment/initialization/delete/push()/pop() skipping some or all of the intended storage writes. Bugfixes: Codegen: Fix internal compiler error when emitting events via module memb…

We would especially like to thank all the contributors that made this release possible: Kamil Śliwak, Matheus Aguiar, Nikola Matić, rodiazet
We are excited to announce the release of the Solidity Compiler v0.8.31! This version of the compiler brings support for the new EVM features introduced by the Fusaka network upgrade, extends the functionality of storage layout specifiers and deprecates the first batch of features scheduled for removal in the 0.9.0 breaking release. We are also adding official ARM Linux builds. Changelog Language…
