 #### :boom: Breaking Change
 
 - Remove the legacy build system. Going forward, only the modern build system is supported, and the `rescript-legacy` command is not available anymore. https://github.com/rescript-lang/rescript/pull/8186 https://github.com/rescript-lang/rescript/pull/8212
 - Remove support for `bsconfig.json`. https://github.com/rescript-lang/rescript/pull/8187
-- `Int.fromString` and `Float.fromString` use stricter number parsing and no longer uses an explicit radix argument, but instead supports parsing hexadecimal, binary and exponential notation.

 - Remove the deprecated uncurried `(. args) => ...` function syntax. https://github.com/rescript-lang/rescript/pull/8211
 - `js-post-build` now passes the correct output file path based on `in-source` configuration: when `in-source: true`, the path next to the source file is passed; when `in-source: false`, the path in the `lib/<module>/` directory is passed. Additionally, stdout and stderr from the post-build command are now logged. https://github.com/rescript-lang/rescript/pull/8190
 - `js-post-build` command now runs in the directory containing the `rescript.json` where it is defined, instead of the unpredictable build invocation directory. This provides consistent behavior in monorepos. https://github.com/rescript-lang/rescript/pull/8195
