Hi, rajman. Spam can't be handled instantly / automatically. Whatever automatic blocking methods we put in place, the spammers always find a way around. When we become aware of a spam post, we do delete it.
Next, please remember to read the forum guidelines before posting. Please don't "bump" your own post. We respond to all posts in order, oldest first, and the date of your post is based on the date of the last post in the thread, not the first. If you bump your own post, you will wait longer for a response.
Unfortunately, in this case, you caused yourself to wait longer for a response by bumping your own post twice.
Please also note that the forums are a free service, open to the public. Because of the volume of traffic we receive, it is not unusual to wait a week from the date of the last post (sometimes longer) for a response. If you see that older posts in the same folder have not yet been answered, then you know that we haven't missed you - we just haven't gotten to your question yet.
Now, on to your question. There is additional information in some of the books, but some have changed more than others. The quant books have been reorganized but most of the material itself is the same. There are additional practice drills in the 5th edition quant books, though.
On the verbal side, the critical reasoning book changed the most - for that one, it might be worth getting the 5th edition book. You're probably fine with RC and SC.
The 4th edition uses OG12 and the 5th edition uses OG13, so just note that.
Finally, the 5th edition included a new book on Integrated Reasoning (this didn't exist for the 4th edition), so you may want to get that one.
For the most part, though, you're fine with your 4th edition books!
