+RABCDAsm Changelog
+==================
+
+RABCDAsm v1.4 (2011.02.xx)
+--------------------------
+
+ * Add support for forward-references for TypeName-kind Multinames
+ * Correctly order classes by dependencies (extends/implements) and reference
+   count
+ * Finish Metadata support
+ * Documentation updates
+
+RABCDAsm v1.3 (2010.11.11)
+--------------------------
+
+ * Fixed double precision problem
+   * This also fixes problems with illegal default values for function
+     parameters (default values for integer parameters are stored as doubles, 
+     which might become out-of-range due to inadequate double precision)
+ * Added Changelog
+ * Documentation markdown fixes
+
+RABCDAsm v1.2 (2010.11.06)
+--------------------------
+
+ * Fixed ref generation for orphan objects which were only referenced
+   by other orphans
+ * Better error handling in `abcexport`; warn when no DoABC tags found
+ * Documentation updates
+
+RABCDAsm v1.1 (2010.06.30)
+--------------------------
+
+ * Private namespaces are now referenced by auto-generated names
+ * Use `:` to delimit namespace and name in QNames for consistency
+    * Warning: this breaks compatibility with v1.0 disassemblies
+ * Fixed relative include paths
+ * Add optional byte offsets to labels, which allows lossless representation
+   of jumps inside instructions and outside the function bounds
+ * Documentation updates
+
+RABCDAsm v1.0 (2010.05.05)
+--------------------------
+
+ * Initial release.

 Limitations
 ===========
 
-* Metadata is currently ignored. I haven't noticed any metadata blocks in any
-  SWF files I've disassembled.
-
-* Floating point numbers may not be disassembled with adequate precision.
-
-* `rabcasm` may create a broken file due to not ordering classes by ancestry.
-
-  The problem originates from the fact that a class's ancestors (extended 
-  class and implemented interfaces) are stored as multinames, and not as 
-  class indices. (This makes sense, since classes may extend objects outside 
-  the current ABC file.) Since `rabcasm` currently doesn't decode multinames, 
-  it is unaware of the class dependencies, and may thus write the classes out 
-  of order. This results in a file that, when opened, will fail to load with 
-  an error message similar to:
-
-  `VerifyError: Error #1014: Class AncestorClassName could not be found.`
-
-  The simple work-around is to re-order the classes as they are declared in 
-  the `.main.asasm` file, and place ancestors before descendants.
+* None known.
