As stated in that news, this is just a bugfix and limited functionality-improving version over the one coming with XOOPS 2.073.
for encoding options, I prefer change the 'select' to 'input' which allows you to add any encoding that you think valid. (Another way is rss encoding auto-detection, which has been implemented in our local language version.)
Currently if you wanna add new encoding options, you have to change the code.
