## Unreleased

### Added
- Implemented [`reset_stdio_count()`](@ref) to provide a public API for
resetting the stdio count ([#1145]).

### Changed
- IJulia was completely refactored to minimize global state ([#1145]). This
allows for better testing (for the first time we can test kernel execution)
and for executing precompilation workloads. We've tried to avoid any breaking
changes but it's possible that some packages may be relying on internals that
have changed. If you have any problems with this release please open an issue
on Github so we can help.

## [v1.29.2] - 2025-07-29
