Google has announced that the first update for its Android M Developer Preview is now available.

The update features various enhancements and bug fixes that are designed to improve the original version of the OS' Developer Preview.

Following in the footsteps of its Android L Developer Preview, Google released the same version for its upcoming Android M software earlier in May of this year.

But unlike the former, the Mountain View-based tech giant promised that it will roll out periodic updates for its Android M Developer Preview. The company said it will continue doing this until the final version of the new OS is stable enough to be released to all users.

Then, on July 9, Jamal Eason, Google's product manager for the Android announced through the Android Developers Blog that the first OTA update for the Android M Developer Preview has been released.

According to Eason's post, the latest update features several firmware changes. Some of these include Android platform permissions to access the device and its external storage, contacts and Wi-Fi and Bluetooth location.

The update also comes with a fix to solve the issue regarding the use of camera permissions with legacy apps.

According to Google, one of the main reasons regarding the release of periodic updates is to gather feedback from users. By reporting issues that they have encountered with the firmware, they'll be able to help the company develop a more stable update for the Android M.

Based on Google's timeline, the next or third update for the Android M Developer Preview is scheduled to arrive sometime during the last weeks of this month. It is also expected to be the final update for the preview version of the OS before it is officially unveiled to the public.

Eason noted that the final version of Android M is scheduled to be released to the public this fall or during the third quarter of 2015.
