Xperia M4 Aqua E2303 5.0 Lollipop 26.1.A.2.147 firmware. Any improvements?

Just flashed 26.1.A.2.147 firmware on my xperia m4 aqua.
How are you finding this update? Any improvements?

I am a little confused... is this newer firmware than 26.1.A.2.99 ???

I wasn t wiping data and app log. Should I? Just wanted to keep my phone data there

Thanks guys.
