Version 0.4.36 introduced an unexpected breaking change and was yanked. In it LocalResult was renamed to MappedLocalTime to avoid the impression that it is a Result type were some of the results are errors. For backwards compatibility a type alias with the old name was added.
As it turns out there is one case where a type alias behaves differently from the regular enum: you can't import enum variants from a type alias with use chrono::LocalResult::*. With 0.4.37 we make the new name MappedLocalTime the alias, but keep using it in function signatures and the documentation as much as possible.
See also the release notes of chrono 0.4.36 from yesterday for the yanked release.
v0.4.36
This release un-deprecates the methods on TimeDelta that were deprecated with the 0.4.35 release because of the churn they are causing for the ecosystem.
New is the DateTime::with_time() method. As an example of when it is useful:
use chrono::{Local, NaiveTime};
// Today at 12:00:00
let today_noon = Local::now().with_time(NaiveTime::from_hms_opt(12, 0, 0).unwrap());
Use different method to ignore feature-dependent doctests (#1534)
Thanks to all contributors on behalf of the chrono team, @djc and @pitdicker!
v0.4.35
Most of our efforts have shifted to improving the API for a 0.5 release, for which cleanups and refactorings are landing on the 0.4.x branch.
The most significant changes in this release are two sets of deprecations.
We deprecated all timestamp-related methods on NaiveDateTime. The reason is that a timestamp is defined to be in UTC. The NaiveDateTime type doesn't know the offset from UTC, so it was technically wrong to have these methods. The alternative is to use the similar methods on the DateTime<Utc> type, or from the TimeZone trait.
