SMTChecker: Fix display error for negative integers that are one more than powers of two. A pragma directive is always local to a source file and if you import another file, the pragma from that file will not automatically apply to the . The most important fix concerns the optimizer which generated invalid code connected to the SHA3 opcode in certain situations. SMTChecker: Fix internal error when an unsafe target is solved more than once and the counterexample messages are different. Yul Assembler: Fix internal error when function names are not unique. Version 0.6.5 of Solidity fixes an important bug and introduces immutable as a major feature. This release deliberately breaks backwards compatibility mostly to enforce some safety features. version 0.4.0 for calls where the output is larger than the input. Code Generator: More efficient code for checked addition and subtraction. This version is synchronized to the Homestead changes on the main Ethereum network and introduces various breaking changes. Further options on this page detail installing commandline Solidity compiler software Features: Inline assembly: support both suicide and selfdestruct opcodes (note: suicide is deprecated). Furthermore, this release finally checks the modifiers view (used to be named constant) and pure on functions. difference is that we do not generally update old releases on the Github release page. Starting on version 0.5.0, the Solidity team switched to a faster release cycle, with minor releases every few weeks (v0.5.0 was released on November 2018, and v0.5.5 on March 2019), and major, breaking-change releases every couple months (with v0.6.0 scheduled for late March 2019). but it comes with limitations, like accessing only the files in your /home and /media directories. The usage of solcjs is documented inside its own Bugfix: combined-json output of solc incorrectly returned the runtime binary instead of the binary. Copyright 2016-2023, The Solidity Authors.
