WalkthroughAdds new tooling interfaces for building function-pointer blobs, many internal codegen helpers and formatting controls, an idempotent filesystem helper for emitting generated pointer files, updates two submodule pointers, and adds documentation/NatSpec and minor formatting changes to scripts, tests, and utilities.

💡 Result:
Commit 1801b0541f4fda118a10798fd3486bb7051c5dd6 is the tagged release forge-std v1.14.0 (released Jan 5, 2026). Breaking change: forge-std now requires Solidity ^0.8.13 (this is the first release with that requirement); for Solidity <0.8.13 you must stay on v1.13.0. [1][2]
Context for the break: the project is explicitly narrowing its compiler-compatibility window (it was already not truly 0.6.* compatible), enabling newer language features and accommodating newer-compiler warnings/changes around “memory-safe assembly” syntax. [3]

💡 Result:
I couldn’t retrieve a public “compare”/commit list for the exact range b8f065fda83b8cd94a6b2fec8fcd911dc3b444fd → 1801b0541f4fda118a10798fd3486bb7051c5dd6 via web sources (those SHAs didn’t resolve in indexed GitHub pages), so I can’t produce an authoritative, itemized changelog for that commit range from search results.
You can generate the changelog locally (most reliable) with:
git clone https://github.com/foundry-rs/forge-std.git
cd forge-std
git fetch --all --tags
# commits in the range:
git log --oneline b8f065fda83b8cd94a6b2fec8fcd911dc3b444fd..1801b0541f4fda118a10798fd3486bb7051c5dd6

Verify Solidity compiler compatibility before merging this forge-std upgrade.
forge-std v1.14.0 (commit 1801b0541f4fda118a10798fd3486bb7051c5dd6) introduces a breaking change: it now requires Solidity ^0.8.13 (the first release to enforce this). Projects using Solidity <0.8.13 must remain on v1.13.0.
Confirm your project's minimum Solidity version is compatible with this requirement before merging. If you need to support older compilers, you will need to keep forge-std on v1.13.0.

Hyphenate compound modifier “sub-parsers”.
Use “sub-parsers” as a compound adjective for correctness and consistency.
