# Version 0.18
## Version 0.18.1 (Mar 25, 2024)
### New Features
* Added support for the draft `Partitioned` attribute.
The new `CookieBuilder::partition()`, `Cookie::partitioned()`, and
`Cookie::set_partitioned()` methods allow enabling and/or disabling the
attribute. Additionally, the attribute is recognized during parsing.
* Added `CookieBuilder::removal()`, counterpart to `Cookie::make_removal()`.
## Version 0.18.0 (Oct 9, 2023)
### Breaking Changes
* The MSRV is now 1.56.
* `Cookie::value()` no longer trims surrounding double quotes. (89eddd)
Use `Cookie::value_trimmed()` for the previous behavior.
* Many methods now expect a `T: Into<Cookie>` in place of `Cookie`. (49ff7b)
Functions and methods that previously accepted a `Cookie` now accept any `T:
Into<Cookie>`. This particularly affects the `CookieJar` API, which now allows
simpler addition and removal of cookies:
* `jar.add(("foo", "bar"));`
* `jar.add(Cookie::build(("foo", "bar")).path("/"));`
* `jar.remove("foo");`
* `jar.remove(Cookie::build("foo").path("/"));`
* `CookieJar::force_remove()` now expects a `T: AsRef<str>` in place of
`&Cookie`.
Force-removal never requires more information than a cookie's name. The API
has been simplified to reflect this.
* `CookieBuilder::finish()` was deprecated in favor of
`CookieBuilder::build()`.
This largely serves as a compile-time notice that calling `finish()` or
`build()` is largely unnecessary given that `CookieBuilder` implements
`Into<Cookie>`.
* `Cookie::named()` was deprecated in favor of using `Cookie::build()` or
`Cookie::from()`.
* `Cookie::named("foo")` is equivalent to `Cookie::from("foo")`.
* `Cookie::build("foo")` begins building a cookie equivalent to
`Cookie::named("foo")`.
### New Features
* Added `Cookie::value_trimmed()` and `Cookie::name_value_trimmed()`.
These versions of `Cookie::value()` and `Cookie::name_value()`,
respectively, trim a matching pair of surrounding double quotes from the
cookie's value, if any are present.
* String-like types, tuples of string-like types, and `CookieBuilder`
implement `Into<Cookie>`.
Implementations of `Into<Cookie>` for string-like types (`&str`, `String`,
`Cow<str>`), tuples of string-like types `(name: string, value: string)`,
and `CookieBuilder` were added. The former implementations create a cookie
with a name corresponding to the string and an empty value. The tuple
implementation creates a cookie with the given name and value strings. The
`CookieBuilder` implementation returns the built cookie.
* `Key` implements `Debug`.
To not leak sensitive information, the representation is simply `"Key"`.
* `CookieBuilder` implements `Borrow{Mut}<Cookie>`, `As{Ref,Mut}<Cookie>`,
`Display`.
* Added `CookieBuilder::inner{_mut}()` to (mutably) borrow cookies being
built.
* Added `PrefixedJar` and `CookieJar::prefixed{_mut}()`, which implement the
cookie prefixes HTTP draft.
## Version 0.18.0.rc.0 (Sep 27, 2023)
See the entry above for 0.18.0.
# Version 0.17
## Version 0.17.0 (Jan 22, 2022)
### Breaking Changes
* Cookie parsing no longer removes a `.` `Domain` prefix. `Cookie::domain()`
now removes a `.` prefix before returning.
As these changes are inverses, they are not likely observable. The change
only affects manually set `domain` values via the `.domain()` builder
method, the `set_domain()` setter method, or similar, which will now have a
prefix of `.` removed when returned by `Cookie::domain()`. This results in
more consistent treatment of `Domain` values.
### New Features
* Added `Cookie::split_parse()` and `Cookie::split_parse_encoded()` methods.
The methods split a `;`-joined cookie string and parse/decode the split
values. They return a newly introduced iterator value of type `SplitCookies`
over the parse results.
### General Changes and Fixes
* Parsing fuzzers were introduced and run for 48 CPU hours without failure.
* `base64` was updated to `0.21`.
# Version 0.16

* Stale doc references to version `0.14` were updated.
## Version 0.15.0 (Feb 25, 2021)
### Breaking Changes
* `Cookie::force_remove()` takes `&Cookie` instead of `Cookie`.
* Child jar methods split into immutable and mutable versions
(`Cookie::{private{_mut}, signed{_mut}}`).
* `Cookie::encoded()` returns a new `Display` struct.
* Dates with year `<= 99` are handled like Chrome: range `0..=68` maps to
`2000..=2068`, `69..=99` to `1969..=1999`.
* `Cookie::{set_}expires()` operates on a new `Expiration` enum.
### New Features
* Added `Cookie::make_removal()` to manually create expired cookies.
* Added `Cookie::stripped()` display variant to print only the `name` and
`value` of a cookie.
* `Key` implements a constant-time `PartialEq`.
* Added `Key::master()` to retrieve the full 512-bit master key.
* Added `PrivateJar::decrypt()` to manually decrypt an encrypted `Cookie`.
* Added `SignedJar::verify()` to manually verify a signed `Cookie`.
* `Cookie::expires()` returns an `Option<Expiration>` to allow distinguishing
between unset and `None` expirations.
* Added `Cookie::expires_datetime()` to retrieve the expiration as an
`OffsetDateTime`.
* Added `Cookie::unset_expires()` to unset expirations.
### General Changes and Fixes

* Added `readme` key to `Cargo.toml`, updated `license` field.
## Version 0.14.0 (May 29, 2020)

### New Features
* Added `Key::from()` to create a `Key` structure from a full-length key.
* Signed and private cookie jars can be individually enabled via the new
`signed` and `private` features, respectively.
* Key derivation via key expansion can be individually enabled via the new
`key-expansion` feature.
### General Changes and Fixes
* `ring` is no longer a dependency: `RustCrypto`-based cryptography is used in
lieu of `ring`. Prior to their inclusion here, the `hmac` and `hkdf` crates
were audited.
* Quotes, if present, are stripped from cookie values when parsing.
# Version 0.13
## Version 0.13.3 (Feb 3, 2020)
### Changes

* The `time` dependency was pinned to `0.2.4` due to upstream breaking changes
in `0.2.5`.
## Version 0.13.1 (Jan 23, 2020)

* `CookieBuilder` gained a lifetime: `CookieBuilder<'c>`.
### General Changes and Fixes
* Added a CHANGELOG.
* `expires`, `max_age`, `path`, and `domain` can be unset by passing `None` to
the respective `Cookie::set_{field}()` method.
