Magento 1.5 on the way.
The first version of Magento I used was 1.3. Instantly I was surprised and shocked at the way in which Magento performed.. There are so many useful features that come as standard but more often than is acceptable, you will be greeted by errors and extensions simply not working.
It is after these sort of things happen a number of times that you realise that Magento is rather fragile. You have to make sure that extensions are suitable for your version. Even if you do everything right you will at some point find a bug. Another couple I found were when moving categories via the backend and also when importing and exporting products.
An issue I am having at present with an installation of Magento 1.4 is that the indexing system has seized up. Luckily the site still works but it is this sort of fragility that means that everytime you press the refresh button, you cross your fingers!
So you can imagine how happy I am to have found that Magento 1.5 has entered the testing phase. Ok, so they are about 9% through this process but I think I am allowed to get a little excited. Anything that makes my life easier is ok with me.
Here are a few things which caught my attention:
Fixed Onepage checkout – Shipping address issues
– added resetting property to save billing address in address book
– added saving of new shipping address
– simplified condition in order preparation routine
Improved Import/Export
Fixed Displaying Out of Stock Products on the front-end
I have had problems with all of the above fixes. Hopefully this will save loads of time in the future.
On one site that I recently finished, the one page checkout was simply not completing. I could add products and proceed to the cart but when it came to selecting the shipping method, the cart would reset. I had to search long and hard to find the fix for this.

@Joe
I found the issue mentioned somewhere on the web, though sadly I cant recall where.
In fact in the end, the issue was resolved by changing the theme of the installation, as it was actually this that was breaking the one page checkout.
Hi, good blog!
I was wondering where you found the fix to the problem you were having with the one page checkout resetting?
Give more details about this topic. Thanks for such a good article blog.
