Here is a good (not perfect) translation provided by me and my co-worker since we're bored at work and nireyes25 never sent more things for us to translate for his English patch:
(Please click the thumbs up icon in the lower right corner of this post if you like that I'm doing this)

Feb 12th:
[Content changes]
1. New Years Cash Shop items have been removed.
2. (Above our translation skills)

[Bug fixes]
1. No longer able to escape out of the battlefield area in Siege.
2. Fixed an issue causing item upgrade to be too easy/successful. -If you took advantage of this, you will be compensated in the future.
