 # Changelog
 
+## [v0.9.0] - 2023-01-??
+
+This release continues support for Go 1.19 and the upcoming Go 1.20.
+
+Noteworthy changes include:
+
+* Randomize the magic number header in `pclntab` - [#622]
+* Further reduce binary sizes with `-tiny` by 4%  - [#633]
+* Reduce the size overhead of all builds by 2% - [#629]
+* Reduce the binary size overhead of `-literals` by 20%  - [#637]
+* Support assembly references to the current package name - [#619]
+* Support package paths with periods in assembly - [#621]
+
+Note that the first two changes are done by patching and rebuilding Go's linker.
+While this adds complexity, it enables more link time obfuscation.
