-## 0.3.0 (2020-01-15)
+## 0.3.1 (2020-01-16)
+### Added
+- Parallelize AVX2 backend ([#87])
+- Benchmark for `ChaCha20Rng` ([#87])
+
+### Fixed
+- Fix broken buffering logic ([#86])

+[#86]: https://github.com/RustCrypto/stream-ciphers/pull/83

+
+## 0.3.0 (2020-01-15) [YANKED]
+
+NOTE: This release was yanked due to a showstopper bug in the newly added
+buffering logic which when seeking in the keystream could result in plaintexts
+being clobbered with the keystream instead of XOR'd correctly.
+
+The bug was addressed in v0.3.1 ([#86]).
+
 ### Added
 - AVX2 accelerated implementation ([#83])
 - ChaCha8 and ChaCha20 reduced round variants ([#84])

 description = """
 The ChaCha20 stream cipher (RFC 8439) implemented in pure Rust using traits
 from the RustCrypto stream-cipher crate, with optional architecture-specific
-hardware acceleration (SSE2, AVX2). Additionally provides the ChaCha8, ChaCha12,
+hardware acceleration (AVX2, SSE2). Additionally provides the ChaCha8, ChaCha12,
 and XChaCha20 stream ciphers, and also optional rand_core-compatible RNGs based
 on those ciphers.
