Check the ChangeLog below for firmware requirements!
INSTALLATION
Put the zip file of the ROM on your sdcard or internal storage, boot into recovery and flash. When coming from stock: boot into TWRP, format data, reboot to recovery and wipe all internal partitions. Then flash the ROM, GApps (if needed) and root (if needed).
Note: There is not going to be a LOS su addon anymore. If you need root, flash a root manager of your choice. No guaranteed support from LOS for this.
When updating from builds, simply dirty flash the ROM.
If coming from 16.0, please see advice below in second post ("UPGRADE LINEAGEOS").

SECURITY ADVICE
Don't flash ROMs or Magisk modules which set SELinux to permissive or you welcome malware on your device!
UPGRADE LINEAGEOS
I have not tried upgrading the device from 16.0 and cannot guarantee that it will work - You should do a backup just in case. If things go wrong, flash it as if coming from stock (see instructions in OP).
UPGRADE FIRMWARE
Grab the Sony Stock firmware using e.g. XPeriFrim. You should always flash the firmware matching the LOS build.
Grab newflasher and put it in the same folder as the firmware files.
Read the newflasher original post on XDA for general instructions!
Remove the following from the folder so they won't get flashed:
all *.ta files (keep the one in the boot/ directory)
cache*.sin
fotakernel*.sin
kernel*.sin
system*.sin
userdata*.sin
vendor*.sin
Turn off your phone
Hold the volume down button and attach it via USB to your system till you see LED turning green
Run newflasher from within this directory to flash the remaining files
You can say yes to the first optional step, in case you don't have working drivers installed.
Skip the second optional step (dumping of trim area), it's useless if your bootloader is unlocked already and takes a long time.
How to get root?
As mentioned before, there will not be an official su addon from LOS anymore. If you need root, flash an unofficial solution.
Google Apps
You can download and install the Google Apps from opengapps.org. You need ARM64 and 10.x. I suggest to *always* use the pico or nano package. If you need additional apps you find them in the Play Store.
MicroG
This ROM doesn't support Signature Spoofing. However we are watching MicroG and check if they provide newer builds e.g. for Android Pie.
Simple Mobile Tools
This is a collection of really awesome Open Source and AD-free Apps! Don't get confused by the name! Especially the Calendar and Gallery app are really good! If you like his stuff, support him by buying the Simple Thanks app.
You can find them in FDroid and the Play Store.

because I prefer the old one. the new one is still in the ROM and enabled by default, but you can choose between 3 or 4 different styles in the settings...

Anyone have this problem on launcher after installing apps from CH Play? There is always an app icon currently installed in the app drawer, but when I click on it, there is no application installed, I tried restarting to see if it lost or not but it still seems there. This error I encountered in the first test but I thought that it should be fixed now but it still hasn't. I hope it will be fixed soon.

I can't say for sure. the December security patch has not been merged into 17.0 yet because of some issues, so I haven't tried a build with it yet either.

The normal play store that's included in gapps? strange cause I haven't experienced this bug. if it doesn't happen with a different launcher, it must be related to trebuchet (the los launcher) then. so likely a los issue upstream.
