New firmware updates are out for the Sony a6300 and a6500. The updates add support for the new Sony E 18-135mm F3.5-5.6 OSS lens and improve overall stability.

You can download them from the following links:

Whether or not they will also release firmware updates for the a5000, a5100 and a6000 to support the new 18-135mm lens remains to be seen. Perhaps there are no issues with these cameras and a firmware update will not be required.
