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.

Changing M4 Aqua CPU clock (Kernel mod.)

Good afternoon. I appoligise for the noob question but is there a way I can edit (I want to add overclock to a kernel) an already made (compiled?) kernel instead of having to completely build the kernel from source? For example, is there a way I can unpack a boot.img and modify the kernel, repack the boot image, and flash it instead of (in my case) going to Sony Developer World and compiling an AOSP kernel from source, I can just modify the frequencies of the CPU in the kernel the phone is currently running and reflash it? Sorry for the complicated and stupid question, i'm very new to kernel modifying... Thanks for any responses and/or help. ^^
