0.10.0 - 2023-10-18

This release adds support for Vyper 0.3.7 (thanks to the funding from VyperLang)! Currently, Vyper frameworks such as Ape are not supported. To run slither on Vyper codebases, target the source directory e.g. run slither ./contracts if the Vyper contracts are in the contracts/ directory.

Additionally, this release includes 5 new detectors, 3 new printers, and several bugs fixes related to recent solidity features. The echidna/medusa integration was sped up and provides more information to the fuzzers.

With the release of crytic-compile 0.3.5, support for foundry projects is significantly improved: Slither can now be run on a single file from a foundry project and detect the necessary imports automatically (ex: run slither contracts/some_file.sol instead of slither . ).
