Upgrading from Groovy 1.3.5 to 1.7.5

I've just inherited an application written in Groovy (version 1.3.5) and would like to upgrade it to the newest release (version 1.7.5).

I can't seem to find a reference that enumerates the differ开发者_开发问答ences in syntax, etc., which I would need to be aware of ... and yes, I looked at http://groovy.codehaus.org

Does anyone know of a good place that lists version changes?

Many thanks,

I think your best bet would be to try it and see where your tests fail.

You do have tests right? ;-)

If not, I'd write some, then try the upgrade and fix where needed.

I don't believe there is a single page where you'd find all the changes from one version to another.

You could maybe collate something by going through all the release notes, but it's probably quicker to just try it.

You can find the changes from one version to another by looking at the release notes. However, the release notes only describe the changes from version N to version N + 1. I don't know how many versions there were between 1.3.5 and 1.7.5, but I'd guess at least 10.

To discover all the changes between 1.3.5 and 1.7.5, you'll have to look at the release notes for each release. Starting from this page, you should be able to find them all, here are some links to get you started.

1.7.5

1.7.4

1.6.9

1.6.8

1.5.8

You should be able to get older releases (and their notes) from the distribution archive.

Having said all that, reading release notes doesn't guarantee anything, (though it's a good way to learn about new features). The only way to be sure that your code runs under the newest version is to compile and test it under that version.
