+* Version 1.0.20
+
+  NOT RELEASED YET.
+
+* Version 1.0.19
+  This release includes all the changes from 1.0.18-stable, as well as two
+additions:
+
+ - New AEADs: AEGIS-128L and AEGIS-256 are now available in the
+`crypto_aead_aegis128l_*()` and `crypto_aead_aegis256_*()` namespaces.
+AEGIS is a family of authenticated ciphers for high-performance applications,
+leveraging hardware AES acceleration on `x86_64` and `aarch64`. In addition
+to performance, AEGIS ciphers have unique properties making them easier and
+safer to use than AES-GCM. They can also be used as high-performance MACs.
+ - The HKDF key derivation mechanism, required by many standard protocols, is
+now available in the `crypto_kdf_hkdf_*()` namespace. It is implemented for
+the SHA-256 and SHA-512 hash functions.
+ - The `osx.sh` build script was renamed to `macos.sh`.
+ - Support for android-mips was removed.
+
+* Version 1.0.18-stable
+ - Visual Studio: support for Windows/ARM64 builds has been added.
+ - Visual Studio: AVX512 implementations are enabled on supported CPUs.
+ - Visual Studio: an MSVC 2022 solution was added.
+ - Apple XCFramework: support for VisionOS was added.
+ - Apple XCFranework: support for Catalyst was added.
+ - Apple XCFramework: building the simulators is now optional.
+ - iOS: bitcode is not generated any more, as it was deprecated by Apple.
+ - watchOS: support for arm64 was added.
+ - The Zig toolchain can now be used as a modern build system to replace
+autoconf/automake/libtool/make/ccache and the compiler. This enables faster
+compilation times, easier cross compilation, and static libraries optimized
+for any CPU.
+ - The Zig toolchain is now the recommended way to compile `libsodium`
+to WebAssembly/WASI(X).
+ - libsodium can now be added as a dependency to Zig projects.
+ - Memory fences were added to remove some gadgets that could be used
+alongside speculative loads.
+ - The AES-GCM implementation was completely rewritten. It is now faster,
+and also available on aarch64, including Windows/ARM64.
+ - Compatibility with CET instrumentation / IBT / Shadow Stack was added.
+ - Emscripten: the `crypto_pwhash_*()` functions have been removed from Sumo
+builds, as they reserve a substantial amount of JavaScript memory, even when
+not used.
+ - Benchmarks now use `CLOCK_MONOTONIC` if possible.
+ - WebAssembly: tests can now run using Bun, WasmEdge, Wazero, wasm3 and
+wasmer-js. Support for WAVM and Lucet have been removed, as these projects
+have reached EOL.
+ - .NET: the minimum supported macOS version is now 1.0.15; this matches
+Microsoft guidelines.
+ - .NET: all the packages are now built using Zig, on all platforms. This
+allows us to easily match Microsoft's requirements, including supported glibc
+versions. However, on x86_64, targets are expected to support at least the
+AVX instruction set.
+ - .NET: packages for ARM64 are now available.
+ - C23 `memset_explicit()` is now used, when available.
+ - Compilation now uses `-Ofast` or `-O3` instead of `-O2` by default.
+ - Portability improvements to help compile libsodium to modern game consoles.
+ - JavaScript: a default `unhandledRejection` handler is not set any more.
+ - Slightly faster 25519 operations.
+ - OpenBSD: leverage `MAP_CONCEAL`.
