Hi All, If it helps I asked those same questions. The replies are below. I did upgrade and transaction went through for v4.2.42, but it will work on v5.x when it is available for download. Strange that my card was charged but have not received an email notification or a key as yet. RitLabs also said it will be released in a few weeks, so I am counting the days when I can try these new features. Hope it's worth the upgrade.
would like to know the price to upgrade to 5 and what is the procedure?
There is a 30% discount for upgrading to v5.xx. The procedure is simple. First you upgrade your key and receive it via e-mail. After that you download the latest version from our web-site and install it over the existing version. Before doing this create a backup under the "Tools" menu.
Will this 188.8.131.52 update run on my present key?
No, the last version to accept your key is v4.0.38.
However, that latest version currently is v4.2.42.
Would you suggest I update or wait for 5?
You can upgrade your key already now and it will be valid starting with version 4.2.38.
When will it be released?In several weeks, we are dong the final preparations.
How long will my upgrade last for updates to new versions if I buy a key to version 5?
From v4.2.38, through the 5.xx series up to v 6.0.99.
