Cargo has an RFC in progress and the registry-side infrastructure for cooldowns is stabilized in Cargo 1.94 (releasing March 5, 2026). Their approach sidesteps the exemption list problem entirely: instead of exempting packages from cooldowns, you explicitly opt in to a new version with cargo update foo --precise 1.5.10, which records the choice in your lockfile. No exclude list to remember to clean up later. In the meantime there’s also cargo-cooldown, a third-party wrapper that enforces a configurable cooldown window on developer machines as a proof-of-concept. Go has an open proposal for go get and go mod tidy, Composer has two open issues, and NuGet has an open issue though .NET projects using Dependabot already get cooldowns on the update bot side since Dependabot expanded NuGet support in July 2025.
I don’t give much fanfare to incremental chip increases because the performance gain is usually minimal. However, the M4 is up to 30 percent faster than the M3, according to Apple. That might be noticeable to even casual users, especially as the years go on and iPadOS becomes more demanding. For power users, it’ll mean more demanding work like video editing will be noticeably quicker.
