Just wanted to drop some info about Kindle jailbreaks for those curious. All this information is as far as I know. Newer methods and exploits could have released.

The latest jailbreak’s can typically be found on the MobileRead website. The current version/exploit is compatible with Kindle devices running the following firmware versions:

KT3, KT4, KOA1, KOA2, KOA3, PW3, PW4, PW5:

5.14.2

5.14.1 (5.14.1.1 on PW5)

5.13.7

5.13.6

5.13.5

5.13.4

KV:

5.13.6

5.13.5

5.13.4

KT2, PW2:

5.12.2.2

KOReader is why a lot of people jailbreak their Kindles and it can be used to tweak settings to make things like PDFs fit better and read unsupported file types like CBZ and EPUB.

If you do jailbreak your Kindle make sure to keep it in airplane mode to prevent automatic updates.
