Two more development builds of Mac OS X 10.5.3 were released recently, according to a report at Apple Insider. Build 9D20, quickly following build 9D19 released last Friday, contains only two known, minor issues. The notes accompanying the build also reduces the areas of focus that developers are asked to keep an eye on while running the build.

Build 9D20 contains nearly 150 fixes and improvements to Leopard. The 10.5.3 update is also expected to fix graphics issues experienced by Penryn-based laptops owners. The frequency of build releases and very short list of known issues gives good reason to believe we'll be seeing the update released very soon.
