+	Version 0.1.1
+
+	Added:
+	 * Dynamic Arrays `[dynamic]Type`
+	 * Dynamic Maps   `map[Key]Value`
+	 * Dynamic array and map literals
+	 * Custom struct alignemnt `struct #align 8 { bar: i8 }`
+	 * Allow `_` in numbers
+	 * Variadic `append`
+	 * fmt.sprint*
+	 * Entities prefixes with an underscore do not get exported on imports
+	 * Overloaded `free` for pointers, slices, strings, dynamic arrays, and dynamic maps
+	 * enum types have an implict `names` field, a []string of all the names in that enum
+	 * immutable variables are "completely immutable" - rules need a full explanation
+	 * `slice_to_bytes` - convert any slice to a slice of bytes
+	 * `union_cast` allows for optional ok check
+	 * Record type field `names` (struct/raw_union/enum)
+	 * ?: ternary operator
+	 * Unions with variants and common fields
+	 * New built-in procedures
+	     - `delete` to delete map entries `delete(m, key)`
+	     - `clear` to clear dynamic maps and arrays `clear(map_or_array)`
+	     - `reserve` to reserve space for the dynamic maps and arrays `reserve(map_or_array)`
+	 * Unexported entities and fields using an underscore prefix
+
+	Removed:
+	 * Maybe/option types
+	 * Remove `type` keyword and other "reserved" keywords
+	 * `compile_assert` and `assert`return the value of the condition for semantic reasons
+
+	Changed:
+	 * thread_local -> #thread_local
+	 * #include -> #load
+	 * Files only get checked if they are actually used
+	 * match x in y {} // For type match statements
+	 * Version numbering now starts from 0.1.0 and uses the convention:
+	 	- major.minor.patch
+	 * Core library additions to Windows specific stuff
+
+	Fixes:
+	 * Many fmt.* fixes
+	 * Overloading bug due to comparison of named types
+	 * Overloading bug due to `#import .` collision
+	 * disallow a `cast` from pointers of unions
+	 * Minor bugs in generated IR code for slices
+
+	To come very Soon™:
+	 * Linux and OS X builds (unofficial ones do exist already)
