# Solidity v0.8.35 is out!

This release introduces Solidity’s first comptime builtin, formalizes how experimental features are exposed behind a new `--experimental` flag, and ships an experimental SSA CFG code generator targeting stack-too-deep and slow compilation in the IR pipeline.

## Notable features:

- `erc7201` is the first comptime builtin in Solidity. It computes the base slot of an ERC-7201 namespaced storage layout from a namespace string, and its result is usable wherever a comptime expression is required, e.g. as the base slot in a `layout at` specifier.

- A new `--experimental` flag formalizes the experimental feature lifecycle. Using any in-development feature now requires `--experimental` (or `settings.experimental` in Standard JSON), and a new docs page lists what’s currently experimental.

- The first major feature under the new experimental lifecycle is an SSA CFG code generator, a new EVM backend for the IR pipeline. The main motivations are stack-too-deep errors and slow compilation, both long-standing pain points. Enable with `--experimental --via-ssa-cfg`.

- v0.8.35 continues the 0.9.0 deprecation work started in 0.8.31, this time warning about identifiers that will be reserved as keywords in 0.9.0:

- Bugfix: in the IR pipeline (`--via-ir`), `--revert-strings strip` was over-stripping the custom-error argument of `require(condition, CustomError(...))`. A failed `require` would revert with empty error data instead of the encoded custom error. Fixed in 0.8.35.
