A big thank you to all contributors who helped make this release possible! 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. Features: C API (jsonCompiler): Export the license method. To learn more about the bug and check if your contract is vulnerable please read this post with further details about the bug. Solidity Team Fixes Code Generation: Remove some non-determinism in code generation. Name resolver: Allow inheritance Bugfixes: We have rebuilt the older versions for wasm but the original asm.js files remain in bin/. may be a choice for you to get everything setup easily. Furthermore, more situations cause exceptions to be thrown. Features: Inline assembly: support both suicide and selfdestruct opcodes (note: suicide is deprecated). Supported versions. In my last blog post, I discussed the issues presented by having to switch between different versions of the Solidity compiler on a daily basis. Thanks for your help @maks-p and all. It also contains some new optimizations with regards to external function calls and enables the new EVM code generator for pure Yul mode. can be expected to compile with 0.x.z where z > y. version then you will need to agree to the license before you can do If you want to perform a source build, please only use solidity_0.8.18.tar.gz and not the source archives generated automatically by GitHub. This release fixes a bug that was introduced in 0.5.14 (the previous release). many new features for the SMTChecker (see below), updates the Solidity v0.8.10 can now report contract invariants and reentrancy properties through the SMTChecker. Solidity v0.8.11 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). A big thank you to all contributors who helped make this release possible! A curated list of awesome Solidity resources, libraries, tools and more - GitHub - bkrem/awesome-solidity: A curated list of awesome Solidity resources, libraries, tools and more . The loaded by the import callback). Optimizer: Some dead code elimination. TypeChecker: Fix internal error when using arrays and structs with user defined value types before declaration. Versions of Solidity on the other hand seem rather complex and hard to keep track of. Features: This release fixes quite some bugs and also adds several new features. difference is that we do not generally update old releases on the Github release page. simply choose your preferred option and follow the steps outlined on the installation page. minimize disruption. You can switch between languages by clicking on the flyout menu in the bottom-left corner With Solidity you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets. >>> solcx.import_installed_solc() [Version ('0.7.0'), Version ('0.6.12')] So if you have not got an IDE and prefer to develop Solidity, Visual Studio 2019 Solidity v0.7.5 adds the ability so select the ABI coder via pragma abicoder v1 and pragma abicoder v2 in preparation for making ABI coder v2 the default for 0.8.0 and introduces --experimental-via-ir which compiles via the new experimental Yul-based compiler pipeline. Inline Assembly: Show useful error message if trying to access calldata variables. A big thank you to all contributors who helped make this release possible! Download the new version of Solidity here. that a build using a different version is faulty. Minimal changes to be made for upgrade: Add payable to all functions that want to receive Ether (including the constructor and the fallback function). When deploying contracts, you should use the latest released Context-dependent path remappings (different modules can use the same library in different versions) Solidity v0.8.15 further down this page. Important Bugfixes: Code Generator: Fix initialization routine of uninitialized internal function pointers in constructor context. Examples: MAX_BLOCKS, TOKEN_NAME, TOKEN_TICKER, CONTRACT_VERSION. 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. This release does not include many features but rather changes that require a backwards-incompatible adjustment in syntax or semantics. We are excited to announce the latest release of the Solidity Compiler, Solidity v0.8.18. Bingo! This button displays the currently selected search type. This Solidity release adds function types. In addition, it also specifies the support of the smart contract for Solidity versions above the specified version. This means that almost all possible Solidity versions . Additionally, v0.7.4 adds constants at file-level. If you need a specific version of Solidity you can install a Homebrew formula directly from Github. Peephole Optimizer: Optimize comparisons in front of conditional jumps and conditional jumps across a single unconditional jump. Solidity - Arrays. after downloading them, you do not have to use HTTPS for the binaries themselves. Smart contract Natspec: Add event Natspec inheritance for devdoc. This release contains several new features and bugfixes and also an important security fix: The ecrecover function can be forced to return invalid data, which can be used to bypass authentication in very special circumstances. You should follow established Code Generation: Avoid writing dirty bytes to storage when copying. Fix internal error when a function has a calldata struct argument with an internal type inside. Language Features: Provide access to creation and runtime code of contracts via type(C).creationCode / type(C).runtimeCode. We strive for a high level of backwards-compatibility. but it comes with limitations, like accessing only the files in your /home and /media directories. There are various ways to install the Solidity compiler, You can also specify release build versions in the tag, for example, for the 0.5.4 release. Solidity Summits usually feature talks & discussions on Solidity, Yul, language design and tooling. None of the questions are mandatory, but keep in mind that filling in as many as possible helps us! Binary packages of Solidity are available at when using inheritance with NatSpec comments and introduces many small improvements to the optimizer. A big thank you to all contributors who helped make this release possible! Solidity was proposed in August 2014 by Gavin Wood; [non-primary source needed] the language was later developed by the Ethereum project's Solidity team, led by Christian Reitwiessner.. Solidity is the primary language on Ethereum as well as on other private blockchains, such as the enterprise-oriented Hyperledger Fabric blockchain. provide early feedback. Solidity v0.7.6 adds better support for calldata types. perform ABI-encoding and fixes several bugs. It helps to avoid extremely time-consuming searches during code optimization. Commandline Interface: Don't return zero exit code when writing linked files to disk fails. immutable variables can be read in the constructor, there is support for retrieving the smallest Use npm for a convenient and portable way to install solcjs, a Solidity compiler. When expanded it provides a list of search options that will switch the search inputs to match the current selection. A big thank you to all contributors who helped make this release possible! Include keccak256() as an alias to sha3(). For example, it would indicate that the source code has been developed for Solidity version 0.4.0 alongside the new versions which do not differ in functionality. A big thank you to all contributors who helped make this release possible! If you pass -DSTRICT_Z3_VERSION=OFF option Bugfix: Properly check the number of Changes: The main change for 0.8.x is the switch to checked arithmetic operations by default. Read more in the respective security alert. These packages are not directly SMTChecker: Fix soundness of assigned storage/memory local pointers that were not erasing enough knowledge. As a relatively young language, Solidity is advancing at a rapid speed. IR Generator: Add missing cleanup for indexed event arguments of value type. Bugfix: Empty single-line comments are now treated properly. being set in each bytecode produced by such a compiler. A big thank you to all contributors who helped make this release possible! Manual jumps in assembly are deprecated in favour of the structured constructs switch, for and function calls also to provide better portability in the future. Solidity Summits usually feature talks & discussions on Solidity, Yul, language design and tooling. 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. 8. it does not refer to any external files that would have to be Important Bugfixes: Fix tuple assignments with components occupying multiple stack slots and different stack size on left- and right-hand-side. A more detailed description of the bugs fixed can be found Language Features: Add support for getters of mappings with string or bytes key types. TypeChecker: Also allow external library functions in. 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. This repository contains current and historical builds of the Solidity Compiler.. Bugfixes: For details on advanced features - see below. install the latest stable version of solc: If you want to help testing the latest development version of Solidity . We recommend against using Hardhat with newer, unsupported versions of Solidity. Download the new version of Solidity here. According to the links in my post, the bugs certainly do affect the TransparentUpgradeableProxy contract. If you want to perform a source build, please only use solidity_0.8.16.tar.gz and not the zip provided by github directly. In some situations, the optimizer generated incorrect code. 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. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Features: Assembly: Add CREATE2 (EIP86), STATICCALL (EIP214), RETURNDATASIZE and RETURNDATACOPY (EIP211) instructions. fixes an important bug, makes overflow checks on multiplication more efficient and adds an LSP feature to Use https://binaries.soliditylang.org instead of https://solc-bin.ethereum.org. Solidity v0.8.10 can now report contract invariants and reentrancy properties through the SMTChecker. Furthermore, we fixed several bugs and the SMTChecker has improved language coverage. ABIEncoderV2: Fix buffer overflow problem when encoding packed array from storage. The most important fix concerns the optimizer which generated invalid code connected to the SHA3 opcode in certain situations. This applies to the compiler output, the linker input and other things. A big thank you to all contributors who helped make this release possible! Posted by Solidity Team on February 1, 2023. This is mainly a bugfix release that corrects a problem with the return value of the low-level delegatecall function and removes some invalid warning messages. Commandline Interface: Fix extra newline character being appended to sources passed through standard input, affecting their hashes. Explicit conversion between bytes and string. the London upgrade, includes Refactoring: Move type checking into its own module. Completing the survey will roughly require 10 minutes of your time. Furthermore, contract types and enums are now allowed as keys for mappings and the doxygen-style comments are better supported by the AST. Common Subexpression Eliminator: Process assembly items in chunks with maximum size of 2000. Furthermore, compiling via the new Yul IR pipeline is now considered production ready. A possible workaround is to temporarily rename
