While the release doesn't bring any new features to the table, it does do something more important: Patches several gaping security holes each of the device's firmware.

According to Samsung, the most vulnerability addressed in the update is one that could allow savvy hackers to manipulate the IMEI of a handset if not blocked off.
This would allow those in possession of a stolen device to circumvent the IMEI blacklist, by reassigning a blacklisted handset a clean IMEI number of resale.
Although, Samsung notes that it's unlikely this specific exploit is present in the Galaxy S10 and Galaxy Note 10 – and rather the Galaxy S9 and Galaxy Note 9.
It's still yet to arrive on the Galaxy S9 and Galaxy S9 Plus.
To see if the update is available for your Galaxy S10, Galaxy Note 10 or Galaxy Note 9, head into Settings, select Software Update and tap Download Updates Manually.
