The final version of 0.8 (known as 'd') is out and available, including the Patreon version (SE) for PC, Linux, and MAC. You can get the full 0.8d SE version for PC/Linux, or a patch file for previous 0.8 versions for PC/Linux/MAC in the downloads.

It's been delayed a bit because of getting the full Android 0.8 version available. It's been difficult to get it working 100% properly, but it is now fixed. Here is the information on it:

ECA: 0.8d SE - Android Version

Here's the official full 0.8d version for the Android. It works differently from the previous versions but it should work with those versions and allow you to keep your saves from previous official versions. Read below and follow the instructions.

If you have installed and played ECA for the Android before:
1. Download and install the APK.
2. Download the archive.rpa file and copy to the /Documents/RenPy_Saves/<appname>/game/ folder.

If you haven't installed and played ECA for the Android before:
Between steps 1 and 2 above, run the game after installation and give it file permissions. Without this, it will cause errors.
