Code Generator: Optimise the fallback function, by removing a useless jump. bundled with necessary DLLs). but it comes with limitations, like accessing only the files in your /home and /media directories. Code generator: properly clean higher order bytes before storing in storage. Solidity v0.8.6 fixes some Including the compiler version in OpenZeppelin Contract's . addition, patch level releases with major release 0 (i.e. A breaking change is introduced > version is bumped to 0.5.0. Note: In some cases, this can also be a potential workaround for build failures.

Most notably, further cleanup of visibility and state mutability has been performed and several unpopular keywords have been removed. The following are dependencies for all builds of Solidity: CMake (version 3.21.3+ on Foster communication between teams working on similar topics. If you need a specific version of Solidity you can install a The first bug is related to immutables of signed integer types shorter than 256 bits. Optimizer: Some dead code elimination. Type checker, code generator: enable access to events of base contracts names. Features: Optimiser: Performance improvements. Contracts You need to install the following dependencies for Windows builds of Solidity: If you already have one IDE and only need the compiler and libraries, If you want to perform a source build, please only use solidity_0.8.11.tar.gz and not the zip provided by github directly. Introducing the newest version of the Solidity Compiler! Homebrew formula directly from Github. If the ^0.6.0 file comes from a dependency, one possible fix is to upgrade that dependency (assuming newer versions use a newer version of solidity). Code Generator: More efficient overflow checks for multiplication. We currently use a 0.x version number to indicate this fast pace of change. Null . IR Generator: Fix IR syntax error when copying storage arrays of functions. For details see our earlier blog post. A more detailed description of the bugs fixed can be found This latest version includes a range of improvements and it also introduces support for the Paris upgrade! Alternatively, you can build for Windows on the command-line, like so: If you are interested what CMake options are available run cmake .. -LH. The first one is related to ABI-encoding nested arrays directly from calldata. If you have any questions, you can try searching for answers or asking on the TypeChecker: Also allow external library functions in. 2. Versions of Solidity on the other hand seem rather complex and hard to keep track of. in the future 1/2 == 0.5 will be true, currently we have 1/2 == 0. Version Pragma: pragma solidity >=0.4.16 <0.9.0; Pragmas are instructions to the compiler on how to treat the code. In this release, this pragma does not generate a warning anymore, so you can (and should) use it in production code. >>> solcx.import_installed_solc() [Version ('0.7.0'), Version ('0.6.12')] 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. Kamil liwak, Leo Alt, nishant-sachdeva, Daniel Kirchner, Marenz, minami, Alessandro Coglio, Alex Beregszaszi, Bhargava Shastry, Dallon Asnes, Dallon Asnes, neel iyer, Christian Parpart, GitHubPang, Mathias Baumann, Omkar Nikhal, Saska Karsi, Tynan Richards, dinah. Language Features: Add support for EIP 165 interface identifiers with type(I).interfaceId. Internal exceptions are now thrown by using an invalid opcode (0xfe), manual exceptions still use an invalid jump. users are sometimes more confident with code than their authors, and and Language Description sections to understand the core concepts of the language. Index access for types bytes1, , bytes32 (only read access for now). Solidity v0.8.9 is a pure bugfix release and fixes two important, but low severity, bugs. In this case git is not necessary and symlinks are resolved transparently, either by serving a copy This forces developers to fix warnings as they arise, so they do not accumulate to be fixed later. that were not supported at the time of release. loaded by the import callback). HTTPS without any authentication, rate limiting or the need to use git. 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. Bugfixes: Internal error about usage of library function with invalid types. Bugfix: Resolve dependencies concerning new automatically. Type Checker: Warning about unused return value of low-level calls and send. General: Allow annotating inline assembly as memory-safe to allow optimizations and stack limit evasion that rely on respecting Solidity's memory model. Apart from these, there are several minor bug fixes and improvements. Code generation: Static arrays in constructor parameter list were not decoded correctly. Introduce .transfer(value) for sending Ether. Starting with 0.6.2 we switched to WebAssembly builds with much better performance. Doing this is not recommended for general use but may be necessary when using a toolchain we are the need to install Solidity locally. and does not contain any features. Solidity v0.8.10 can now report contract invariants and reentrancy properties through the SMTChecker. Source : | Last Update : Fri, 18 Nov 22 Answers related to how to check installed npm package version in node js Yul Optimizer: Prevent the incorrect removal of storage writes before calls to Yul functions that conditionally terminate the external EVM call. Report warnings. if you want to be sure whether you are downloading a wasm or an asm.js binary. Check out the latest Solidity Core Team Updates. Blog Archive. TypeChecker: Improved error message for constant variables with (nested) mapping types. fixes an important bug. 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 We recommend against using Hardhat with newer, unsupported versions of Solidity. This release fixes a bug in the Yul optimizer related to break and continue statements in loops. a flag Code Generation: Fix data corruption that affected ABI-encoding of calldata values represented by tuples: structs at any nesting level; argument lists of external functions, events and errors; return value lists of external functions. My module.exports in hardhat-config.js looks like this: Use https://binaries.soliditylang.org instead of https://solc-bin.ethereum.org. This release mainly introduces inline assembly (documentation). rebuilt the older versions for wasm but the original asm.js files remain in bin/. Download the new version of Solidity Solidity 0.5.14 sets the default EVM version to Istanbul and is targeted as the last release in the 0.5.x series. Solidity can now detect uninitialized storage pointers using control-flow analysis. Furthermore, this release finally checks the modifiers view (used to be named constant) and pure on functions. It is interesting to read more about the later history of the Hawarden. The bug has been reported by John Toman of the Certora development team. Ethereum StackExchange, or may be a choice for you to get everything setup easily. Bugfix: Accessing fixed-size array return values. but you should avoid using them when writing new tools: Use emscripten-wasm32/ (with a fallback to emscripten-asmjs/) instead of bin/ if If you are new to the concept of smart contracts we recommend you to get started by digging community efforts. The Docker image runs the compiler executable, so you can pass all compiler arguments to it. Furthermore, compiling via the new Yul IR pipeline is now considered production ready. Bugfixes: In addition to releases, we provide nightly development builds with the When expanded it provides a list of search options that will switch the search inputs to match the current selection. This button displays the currently selected search type. This is also the location where you can find the nightly builds. Bugfix: combined-json output of solc incorrectly returned the runtime binary instead of the binary. that a build using a different version is faulty. various improvements to Yul to EVM code transformation, the SMTChecker and some bugfixes. patch level changes follow. This is a bugfix release for the 0.4.x series that contains backported fixes for important bugs that affected code generation. Type Checker: Warn about assignments involving multiple pushes to storage. of the current nightly build, but without the prerelease specifier. You can verify the integrity of the binary by comparing its keccak256 hash to The default build configuration requires a specific Z3 version (the latest one at the time the Linker stage for compiler to insert other contracts addresses (used for libraries). We distribute the Solidity compiler through Homebrew Bugfixes: Solidity is statically typed, supports inheritance, libraries and complex Improved commandline interface (breaking change). EVM: Set the default EVM version to "Paris". This behaviour works well with the version pragma. Standard Json Input: Support the prefix file:// in the field urls. Bugfix: Value transfer used in clone contracts. 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. Command-line tool for retrieving source code. Introducing the newest version of the Solidity Compiler! The bug is considered to have a severity level of low but is present in all prior versions of Solidity. https://github.com/ethereum/remix-live/tree/gh-pages and download the .zip file as Sokt, is the software written by Web3 Labs to tackle these problems and to streamline the experience for developers.The great news is that Web3j now uses the Sokt library to compile Solidity code. Fix internal error when a function has a calldata struct argument with an internal type inside. Solidity v0.7.1 adds functions at file-level and fixes several small bugs. AST: export all attributes to JSON format. 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. Pulling the solc-js repository directly will work. This release fixes a bug related to calldata structs in ABIEncoderV2 and calldata decoding in V1. you should fork Solidity and add your personal fork as a second remote: This method will result in a prerelease build leading to e.g. A possible workaround is to temporarily rename /lib/cmake/Boost-1.70.0 Bugfix: Prevent usage of some operators. allows calldata for all variables and provides a mechanism to specify an import directory. Type checker: disallow inheritances of different kinds (e.g. Yul Optimizer: Allow replacing the previously hard-coded cleanup sequence by specifying custom steps after a colon delimiter (. very stable, they contain bleeding-edge code from the development branch and are Code Generator: Fix internal error when doing an explicit conversion from. If you need a specific version of Solidity you can install a Homebrew formula directly from Github. Once you are accustomed to the basics, we recommend you read the Solidity by Example We are getting closer to that Solidity 1.0 release (unless of course after 0.9 comes 0.10). Solidity v0.8.15 Windows, 3.13+ otherwise), Boost (version 1.77 on This contains the Clang C++ compiler, the All solidity source code should start with a "version pragma" a declaration of the version of the Solidity compiler this code should use. Solidity is an object-oriented, high-level language for implementing smart Features: Assembly: Add CREATE2 (EIP86), STATICCALL (EIP214), RETURNDATASIZE and RETURNDATACOPY (EIP211) instructions. A big thank you to all contributors who helped make this release possible! Compiler option to output runtime part of contracts. Note that the new revert function will only be gas-efficient starting from homestead. can be expected to compile with 0.x.z where z > y. Posted by Solidity Team on February 1, 2023. Features: Add assert(condition), which throws if condition is false (meant for internal errors). Language Features: Add support for getters of mappings with string or bytes key types. Identify needs for the smart contract ecosystem for Ethereum. In previous versions of Solidity (prior Solidity 0.8.x) an integer would automatically roll-over to a lower or higher number. Release configuration, but all others work. Solidity v0.7.3 fixes a bug in the dynamic-array cleanup. Solidity examples like the one highlighted here feature the pragma directive informing the writing of source code for Solidity version 0.4.16. Here is the list of components that should be installed contain breaking changes. According to the links in my post, the bugs certainly do affect the TransparentUpgradeableProxy contract. Solidity v0.8.0 is out, bringing you SafeMath by default! tools that are required for building C++ applications on OS X. custom operators for user-defined value types, Allow defining custom operators for user-defined value types via, SMTChecker: New trusted mode that assumes that any compile-time available code is the actual used code, even in external calls. Language Features: Allow contract types and enums as keys for mappings. You might want to install ccache to speed up repeated builds. If you would decrement 0 by 1 (0-1) on an unsigned integer, the result would not be -1, or an error, the result would simple be: MAX (uint).
