Bumps undici to 6.28.0 and updates ancestor dependency hardhat. These dependencies need to be updated together.

Updates undici from 5.28.4 to 6.28.0

Release notes

Sourced from undici's releases.

v6.28.0

⚠️ Security fixes

  • GHSA-m8rv-5g2x-5cg5: a malicious type property on a duck-typed blob-like HTTP/1.1 request body could inject CRLF sequences into the generated content-type header. Undici now coerces and validates the value before adding it to the request. Fixed by 740a0b7c.
  • GHSA-8xcm-r25x-g524: the retry interceptor could expose a stale Content-Length after resuming a partial response, potentially causing downstream response desynchronization, hangs, or corruption. Undici now rejects partial responses whose Content-Length is inconsistent with Content-Range. Fixed by cba3a52a, with corrected fixtures in 4fd5a0c6.
  • GHSA-v3r7-h72x-cjcm: unsanitized domain and unparsed values passed to setCookie() could inject cookie attributes. Undici now validates cookie domains, paths, and unparsed attributes more strictly. Fixed by af748404.

GHSA-4cwx-7wf7-3272 and GHSA-jr45-8vmc-qm54 affect the cache interceptor in Undici v7 and v8; Undici v6 is not in their affected version ranges.

v6.27.0

⚠️ Security Release

This release line addresses 4 security advisories.

Action required: Upgrade to undici 6.27.0 or later.

npm install undici@^6.27.0

Note on patched version: the v6 fixes shipped in v6.27.0, not 6.26.0 — v6.26.0 contains only the chunked-EOF fix (#5308) and the version bump, none of the security fixes below.

The v6 line is not affected by the SOCKS5 advisories (GHSA-vmh5-mc38-953g, GHSA-hm92-r4w5-c3mj), the shared-cache disclosure (GHSA-pr7r-676h-xcf6), or the 8.x-only WebSocket regression (GHSA-38rv-x7px-6hhq).

Updates hardhat from 2.22.7 to 3.12.0

Release notes

Sourced from hardhat's releases.

Hardhat v3.12.0

This release includes two new features: negative test filtering with the --grep-exclude flag for both Solidity tests and Mocha test suite, and experimental Amsterdam "EIP-7843: SLOTNUM" support, see our Amsterdam support guide.

Changes

  • #8442 4904c72 Thanks @​ChristopherDedominici! - Support test name filter negation (--grep-exclude) for Solidity and Mocha tests.

  • #8472 2a66c2e Added experimental EIP-7843 support to the Amsterdam hardfork: blocks now include the slotNumber header field, and the SLOTNUM (0x4b) opcode returns it. EDR has no consensus layer, so the value is simulated: it increments by one per mined block, starting at 0 on a new chain, or from the forked block's slot number when forking.

  • #8464 b2b69f7 Thanks @​nishant-uxs! - Prefer environment variables over configurationVariables hooks when resolving config vars.

  • #8474 49cc2f0 Thanks @​Wodann! - Report chain type to Google Analytics

  • #8458 0c60e08 Thanks @​schaable! - Fixed project initialization so that compilation and build output directories are never copied from a template into a new project.

  • #8472 2a66c2e Thanks @​kanej! - Fixed empty stack traces on Solidity test failures when running with -vvv or above.

  • #8472 2a66c2e Thanks @​kanej! - Fixed missing stack traces when an invariant already fails on its initial check, when running with -vvv or above.

  • #8470 341807c Thanks @​kanej! - Update the chokidar runtime dependency to its latest major version.

  • #8470 4a71543 Thanks @​kanej! - Update the p-map dependency.

  • #8461 841423a Thanks @​kanej! - Reduce installation warnings with updated dependencies.

💡 The Nomic Foundation is hiring! Check our open positions.

Hardhat v3.11.1

This release removes the Hardhat 2 option from project initialization and fixes how Solidity files are classified when the same directory is configured for both sources and tests.

Changes

  • #8451 5c9d4a4 Thanks @​kanej! - Remove Hardhat 2 option from init process

  • #8452 724b7cd Thanks @​kanej! - Fixed Solidity source classification so that a directory listed in both paths.sources.solidity and paths.tests.solidity is treated as a source.

  • Updated dependencies:

    • @​nomicfoundation/hardhat-utils@​4.1.6

💡 The Nomic Foundation is hiring! Check our open positions.

Hardhat v3.11.0

This release adds two further EIPs to Hardhat's experimental Amsterdam support: EIP-7778: block gas accounting without refunds and EIP-7928: Block-Level Access Lists. See our Amsterdam support reference for full details of how these work within Hardhat.

3.11.0

Minor Changes

  • #8447 dff401d Thanks @​kanej! - Added experimental EIP-7778 support to the Amsterdam hardfork: a block's gasUsed excludes gas refunds; transaction receipts are unchanged.

  • #8447 dff401d Thanks @​kanej! - Added experimental EIP-7928 support to the Amsterdam hardfork: blocks on Amsterdam now include the blockAccessListHash header field. The value is simulated, not the real keccak256(rlp(blockAccessList)).
