Solidity versions prior to 0.5.10 can fail to correctly link against Boost versions 1.70+. Only the hash of the compiler binary itself will change due to the replacement, but the new binary will always produce byte-identical output. Immutables: Fix wrong error when the constructor of a base contract uses. can be expected to compile with 0.x.z where z > y. Our SMT tests do not account for these differences and Code Generator: Fix internal error when doing an explicit conversion from. Let's explore how you can migrate your contracts today. Since the Linux binary is not completely static (it dynamically loads Z3 and consequently glibc), it would not run with older glibc when built against newer one. For a detailed explanation, please see the documentation or refer to the list below that shows every single change. allows to catch panic errors and adds other small improvements. We have Yul Optimizer: Fix bug in redundant assignment remover in combination with break and continue statements. adds a first implementation of a Language Server, allows a safer way to A big thank you to all contributors who helped make this release possible! The second bug is triggered in certain inheritance structures and can cause a memory pointer to be interpreted as a calldata pointer or vice-versa. Solidity Team This release fixes important but very unlikely bugs and further completes ABIEncoderV2, SMTChecker and Yul and improves the optimizer. Check out the latest Solidity Core Team Updates. If you are new to the concept of smart contracts we recommend you to get started by digging provide early feedback. Locale set in the environment is now completely ignored. Binaries do not require installation or unpacking (with the exception of older Windows builds Improved commandline interface (breaking change). Language Features: Inline Assembly: Apart from further invisible work on the Yul optimizer, the Solidity to Yul code generation, the eWasm backend and the SMT checker, this release contains two important bug fixes related to storage arrays. You can specify error reason strings for revert and require (support by tooling is still pending). We took this opportunity and also extended the use of these function call options to specifying the gas and value options in external function calls: c.f{value: 10, gas: 20000}(arg1, arg2). Assembler: Avoid duplicating subassembly bytecode where possible. ABI Encoder: When ABI-encoding values from calldata that contain nested arrays, correctly validate the nested array length against. For more details, please see buglist.json. Download the new version of Solidity here. Apart from that, the support for calldata structs and arrays by ABIEncoderV2 is almost finished now, we added some more optimizer rules and added enums and one-dimensional arrays to the SMT checker. Starting with 0.6.2 we switched to WebAssembly builds with much better performance. Bugfixes: Introduce .transfer(value) for sending Ether. A big thank you to all contributors who helped make this release possible! non-emscripten builds. We also added some static analysis features to the compiler, but most changes were done under the hood to pave the way for using the new Yul-based optimizer with ABIEncoderV2. Changes include explicit virtual and override keywords in inheritance, support for try/catch, splitting the fallback function into a receive Ether function and an actual fallback function and limitations on how the length of an array can be changed, among others. This affected code generation. Since we usually do not backport Solidity v0.6.12 adds more flexibility repository. We suggest building Bugfix: Disallow assignment from literal strings to storage pointers. They are not meant for production use. If you need a specific version of Solidity you can install a Homebrew formula directly from Github. Deposit(address,bytes32,uint256)), except you declared the event with the anonymous specifier) data - string - It contains one or more 32 Bytes non-indexed arguments of the log blockNumber - string - The block number where this log was in. This release improves the usability of interfaces, fixes some bugs, extends the SMT checker and provides an early preview of the Yul optimizer. Doing this is not recommended for general use but may be necessary when using a toolchain we are If you need a specific version of Solidity you can install a Type System: Use correct type name for contracts in event parameters when used in libraries. SMTChecker: Improved readability for large integers that are powers of two or almost powers of two in error messages. Refactoring: Move type checking into its own module. You can also verify the integrity of the binary by comparing its sha256 hash to Additionally, v0.7.4 adds constants at file-level. History. Please upgrade if you are using array slices, backslashes in string literals for ABIEncoderV2 or are concerned about non-payable constructors. Solidity is statically typed, supports inheritance, libraries and complex emscripten-wasm32/list.json you will find the following information about version 0.7.4: You can find the binary in the same directory under the name Correctly report source locations of parenthesized expressions (as part of tuple story). Note, however, that while the nightly builds are usually You can learn about it at length in our feature deep-dive blogpost.

This latest version includes a range of improvements and it also introduces support for the Paris upgrade! This latest version includes a range of improvements and it also introduces support for the Paris upgrade! This is a major breaking release of the Solidity compiler and language. Solidity v0.8.9 is a pure bugfix release and fixes two important, but low severity, bugs. Solidity v0.7.6 adds better support for calldata types. Important Bugfixes: Fix tuple assignments with components occupying multiple stack slots and different stack size on left- and right-hand-side. This You can now create complete contracts in Yul through the support of the Yul object format and the special functions datasize, dataoffset and datacopy. fixes an important bug. Features: Syntax Checker: Deprecated throw in favour of require(), assert() and revert(). Code Generator: Avoid including references to the deployed label of referenced functions if they are called right away. The following C++ compilers and their minimum versions can build the Solidity codebase: For macOS builds, ensure that you have the latest version of Code Generation: Avoid writing dirty bytes to storage when copying. The following are dependencies for all builds of Solidity: CMake (version 3.21.3+ on Files are served over both HTTP and HTTPS. m1guelpf/lil-web3 - Simple, intentionally-limited versions of web3 protocols & apps. Data types are of two types: When deploying contracts, you should use the latest released version of Solidity. Important Bugfixes: ABI Encoder: When ABI-encoding values from calldata that contain nested arrays, correctly validate the nested array length against calldatasize() in all cases. Docker images of Solidity builds are available using the solc image from the ethereum organisation. allows calldata for all variables and provides a mechanism to specify an import directory. This release adds reason strings for compiler-generated reverts if you specify revert-strings debug or use the setting settings.debug.revertStrings = "debug". Including the compiler version in OpenZeppelin Contract's . Explicit conversion between bytes and string. We want to provide a preview release binary for everyone to try out so that you can give your feedback. version using the following commands: The nightly version can be installed using these commands: Furthermore, some Linux distributions provide their own packages. Code Generator: More efficient overflow checks for multiplication. Commandline Interface: Fix extra newline character being appended to sources passed through standard input, affecting their hashes. Yul EVM Code Transform: Generate more optimal code for user-defined functions that always terminate a transaction. We currently use a 0.x version number to indicate this fast pace of change.

Constructors should now be defined using constructor(uint arg1, uint arg2) { } to make them stand out and We again introduced several changes that are scheduled for version 0.5.0 and can be activated using pragma experimental "v0.5.0";. replacement. that a build using a different version is faulty. In addition to that, we added a new commandline option for improved (colorized) diagnostics formatting. Furthermore, breaking changes as well as new features are . We also improved our testing framework which now allows for semantics tests to run in 4 seconds instead of 1 minute. A big thank you to all contributors who helped make this release possible! This release contains no changes outside of the documentation. This only happens in solc-bin. is in fact reachable. Solidity v0.8.2 adds an optimizer stage that can inline small amounts of code to save gas and you could install Visual Studio 2019 Build Tools. Compiler Features: Control Flow Graph: Warn about unreachable code. It also contains a fix for a long-standing bug that can result in code that is only used in creation code to also be included in runtime bytecode.

Furthermore, it comes with a considerably broadened language support of the SMTChecker. It was introduced in Solidity 0.6.5. Solidity v0.6.8 fixes three important bugs in the code generator and introduces a recommendation to use SPDX license identifiers. Solidity v0.8.1 introduces Optimizer: Some dead code elimination. when using inheritance with NatSpec comments and introduces many small improvements to the optimizer. To learn more about the bug and check if your contract is vulnerable please read this post with further details about the bug. The Solidity version pragma statement in these files doesn't match any of the configured compilers in your config. always analyze all files in a project. A big thank you to all contributors who helped Changes: Breaking change in storage encoding: Encode short byte arrays and strings together with their length in storage. Bugfix: Resolve dependencies concerning new automatically. Some people do not even consider it a bug, though, which might explain why it was undiscovered for so long: A private function can be overridden in a derived contract by a private function of the same name and types. out-of-the-box but it is also meant to be friendly to third-party tools: The content is mirrored to https://binaries.soliditylang.org where it can be easily downloaded over (via git, HTTPS, IPFS or just have it cached locally) and verify hashes of the binaries Internal exceptions are now thrown by using an invalid opcode (0xfe), manual exceptions still use an invalid jump. In other words: You will not need SafeMath Solidity v0.7.4 fixes a storage corruption bug of medium severity. To This setup means that a file with a pragma solidity ^0.5.0 will be compiled with solc 0.5.5 and a file with a pragma solidity ^0.6.0 will be compiled with solc 0.6.7.. Fix internal error when a function has a calldata struct argument with an internal type inside. There are also two important bug fixes: One was an oversight in the way bytes variables are allocated in memory and can reduce the memory requirements 32-fold. Linker stage for compiler to insert other contracts addresses (used for libraries). Solidity v0.6.7 introduces support for EIP-165 via type(InterfaceName).interfaceId. You signed in with another tab or window. Inline Assembly: Show useful error message if trying to access calldata variables. Posted by Solidity Team on February 1, 2023. is because breaking changes, as well as new features and bug fixes are introduced regularly. many new features for the SMTChecker (see below), updates the Bugfixes: Code generator: throw if calling the identity precompile failed during memory (array) copying. Conversions between Literals and Elementary Types, Error handling: Assert, Require, Revert and Exceptions, Access to External Variables, Functions and Libraries, Compiler Input and Output JSON Description, Differences between Optimized and Non-Optimized Code, Encoding of the Metadata Hash in the Bytecode, Usage for Automatic Interface Generation and NatSpec, Changes the Compiler Might not Warn About, Integrated (Ethereum) Development Environments, Third-Party Solidity Parsers and Grammars. The wrapper now requires at least nodejs v10. and does not contain any features. // SPDX-License-Identifier: MIT // compiler version must be greater than or equal to 0.8.10 and less than 0.9.0 pragma solidity ^0.8.10; contract HelloWorld { string public greet = "Hello World!"; Solidity-Types This repository contains current and historical builds of the Solidity Compiler.. The main goal is to have a resulting bytecode size similar to the old ABI encoder, while having more runtime checks for a stricter decoding process. package manager for installing external dependencies. In order to compile contracts using a specific version of Solidity, the solc.loadRemoteVersion(version, callback) method is available. SMTChecker: Fix display error for negative integers that are one more than powers of two. Now Solidity 0.8 has been released only 5 months after the 0.7 release! The default build configuration requires a specific Z3 version (the latest one at the time the TypeChecker: Also allow external library functions in. The SHA-256 hash of the old binary was a1c0f33eb4482c26f56719ecf62b0ee05d7d7a4f8264ffbddf9ebcd9095c32bd. Download the new version of Solidity here. A big thank you to all contributors who helped make this release possible! Bugfix: Problem with strings as mapping keys. This release mainly fixes an optimizer bug related to multiple shift opcodes that was introduced in the previous release. My module.exports in hardhat-config.js looks like this: The default view of the Solidity Compiler shows the basic configuration. For example, the command below pulls the stable version of the solc image (if you do not have it already), For details about the bug, please see the official announcement. software development best-practices when writing your smart contracts. our Gitter channel. Join the Solidity forum, where existing properties of the language and proposals for new language features can be discussed. For example in Tuple expressions ((1,2,3) or return (1,2,3);) Declaration and assignment of multiple variables (var (x,y,) = (1,2,3,4,5); or var (x,y) = f();) Destructuring assignment ((x,y,) = (1,2,3)) Handling of multiple source files in the json compiler. Code Generator: Fix internal error when accessing the members of external functions occupying more than two stack slots. will likely fail with a different version than the one they were written for. When changes are merged, the version should be bumped according The It might happen that a file can be compiled with more than one of your configured compilers, for example a file with pragma solidity >=0.5.0.In that case, the compatible compiler with the highest version will be used (0.6.7 in . Typically now, to a certain degree, this is easy, as newer versions than y will still support feature x, so you can also run your code with versions y+1, y+2, and so on. We set up a GitHub organization and translation workflow to help streamline the Pragma is generally the first that we do not rename them if the naming convention changes and we do not add builds for platforms loaded by the import callback). Whenever we code in solidity we always see something like pragma solidity ^0.6.0; Do you guys wonder what actually is 'pragma'? This means that x + y will throw an exception on overflow. Optimizer: Knowledge about state was not correctly cleared for JUMPDESTs Yul Optimizer: Allow replacing the previously hard-coded cleanup sequence by specifying custom steps after a colon delimiter (. SMTChecker: Fix internal error caused by unhandled. supported platforms at solc-bin. if you ever want to start again from scratch. Access to types declared in other contracts and libraries via .. that were not supported at the time of release. Hardhat supports projects that use different, incompatible versions of solc. For more details, see the release announcement. Dec 7, 2022. contain breaking changes. solidity/releases. Change the pragma or configure additional compiler versions in your hardhat config. from ethereumjs-util in JavaScript. Important Bugfixes: ABIEncoderV2: Fix bugs related to loading short value types from storage when encoding an array or struct from storage. It is influenced by C++, Python and JavaScript. Solidity versions follow Semantic Versioning. Load verified contracts from Etherscan using contract address SEE MORE. This release fixes a bug in the Yul optimizer. A Computer Science portal for geeks. 2022 Solidity Team Code of Conduct Template by CloudCannon. explained on that page. TypeChecker: Fix internal error when using arrays and structs with user defined value types before declaration. Solidity project uses CMake to configure the build. solc-bin. Code generator: Inject the Swarm hash of a metadata file into the bytecode.
