41+
- Add `doc_cfg`
42+
- zeroize entire capacity of `String`
43+
- zeroize entire capacity of `Vec`
44+
45+
## 1.1.0 (2019-12-02)
46+
- Add `TryZeroize` trait
47+
- Add `From<Z: Zeroize>` impl for `Zeroizing<Z>`
48+
- Remove `bytes-preview` feature
49+
50+
## 1.0.0 (2019-10-13)
51+
- Initial 1.0 release 🎉
52+
- zeroize_derive: Remove legacy `no_drop` attribute support
53+
- Rename `bytes` feature to `bytes-preview`
54+
- Further relax `Zeroize` trait bounds for `Vec`
55+
- Derive `Clone`, `Debug`, and `Eq` for `Zeroizing`
56+
57+
## 1.0.0-pre (2019-09-30)
58+
- Loosen `Vec` trait bounds for `Zeroize`
59+
60+
## 0.10.1 (2019-09-03)
61+
- (Optionally) Impl `Zeroize` for `Bytes` and `BytesMut`
62+
63+
## 0.10.0 (2019-08-19)
64+
Barring unforeseen circumstances, this release aims to be the last `0.x`
65+
release prior to a `zeroize` 1.0 release.
66+
67+
- Disable `zeroize_derive` Cargo feature by default
68+
- Remove `std` feature in favor of `alloc`; MSRV 1.36+
69+
- Deprecate `#[zeroize(no_drop)]` attribute
70+
- Use 1.0 `proc-macro2`, `quote`, and `syn` crates
71+
72+
## 0.9.3 (2019-07-27)
73+
- Improved attribute parser; fixes nightly build
74+
75+
## 0.9.2 (2019-06-28)
76+
- README.md: add Gitter badges; update image links
77+
78+
## 0.9.1 (2019-06-04)
79+
- Impl `Zeroize` for `Option<Z: Zeroize>`
80+
81+
## 0.9.0 (2019-06-04)
82+
**NOTICE**: This release changes the default behavior of `derive(Zeroize)`
83+
to no longer derive a `Drop` impl. If you wish to derive `Drop`, you must
84+
now explicitly add a `#[zeroize(drop)]` attribute on the type for which you
85+
are deriving `Zeroize`.
86+
87+
- Remove CPU fences
88+
- Remove scary language about undefined behavior
89+
- Bound blanket array impls on `Zeroize` instead of `DefaultIsZeroes`
90+
- Require `zeroize(drop)` or `zeroize(no_drop)` attributes when deriving
91+
`Zeroize` .
92+
- Support stablized 'alloc' crate
93+
94+

95+
- Impl `Drop` by default when deriving `Zeroize`
96+
97+

98+
- Use synstructure for custom derive
99+
- Add explicit array impls for `DefaultIsZeroes`
100+
- Remove `nightly` feature
101+
- Add `Zeroizing<Z>` to zeroize values on drop
102+
103+
## 0.6.0 (2019-03-23)
104+
- Add ZeroizeOnDrop marker trait + custom derive
105+
- Custom derive support for `Zeroize`
106+
- Rename `ZeroizeWithDefault` to `DefaultIsZeroes`
107+
108+
## 0.5.2 (2018-12-25)
109+
- Add `debug_assert!` to ensure string interiors are zeroized
110+
111+
## 0.5.1 (2018-12-24)
112+
- Avoid re-exporting the whole prelude
113+
114+
## 0.5.0 (2018-12-24)
115+
This release is a rewrite which replaces FFI bindings to OS-specific APIs with
116+
a pure Rust solution.
117+
118+
- Use `core::sync::atomic` fences
119+

120+

- Replace `secure_zero_memory` with `Zeroize`
133+
134+
## 0.2.0 (2018-10-11)
135+
- Add `Zeroize` trait
136+
137+
