We last reported about the release of Windows 10 Mobile Build 14393.189 as the Anniversary update CU build for everyone. It was later released to Release Preview Ring too. We also reported about Windows 10 Mobile Build 14393.201 appearing on BuildFeed.
Now a newer Anniversary update build has appeared on BuildFeed. Build 14393.206 that has shown up now, may also bring lots of fixes and improvements for issues faced with the Anniversary update.
Build 14393.206 has been compiled on September 12. Though it may not be released to non-insiders, as by next month we may see more release candidates emerging. It may be headed to Slow / Release Preview Rings however for testing and feedback.
