v0.10.0

This release represents a significant redesign of the secrecy crate. We will update this section
with upgrade instructions based on feedback from people upgrading, as it's been a long time since
the previous release, and this release includes a number of breaking changes.

The most notable change is the generic Secret<T> type has been removed: instead use SecretBox<T>
which stores secrets on the heap instead of the stack. Many of the other changes fall out of this
change and things which were previously type aliases of Secret<T> are now type aliases of
SecretBox<T>.

This unfortunately means this crate no longer has support for "heapless" no_std targets. We don't
have a good solution for these targets, which was a motivation for this change in the first place.

Added

• SecretBox::{init_with, try_init_with} (#​1212)
• SecretBox::init_with_mut (#​1213)
• ?Sized bounds for SecretBox (#​1213)
• SecretSlice<T> (#​1214)

Changed

• Rust 2021 edition upgrade (#​889)
• MSRV 1.60 (#​1105)
• SecretBox<T> is now a newtype rather than a type alias of `Secret<Box> (#​1140)
• SecretString is now a type alias for SecretBox<str> (#​1213)
• Disable serde default features (#​1194)

Removed

• alloc feature: now a hard dependency (#​1140)
• bytes crate integration: no replacement (#​1140)
• DebugSecret trait: no replacement (#​1140)
• Secret<T>: use SecretBox<T> instead (#​1140)
