The goal of the 3.10 release is to improve the process of making Squeak releases and to improve the quality of the code. The release team is not concentrating on adding features or packages, rather in improving testing, in making Squeak more modular, and in getting rid of bad code. However, we expect to add features and packages. These will come from you. Naturally, they must pass the quality standards, and we would prefer to add things that have been tried out by more than the author, and that are generally considered to be a good idea.
In general, changes will come through Mantis (the squeak bugs and changes managagement system). Ideally, a Mantis patch will be a [[Monticello]] package, but we will also accept .cs files, though we will first convert them to .mcz Monticello files. Ideally, changes will be approved by one of the stewards, though if code does not have a steward or if the stewards are not responsive, the release team will approve them.
You can get the latest image from http://ftp.squeak.org/3.10alpha/
You can also get the latest 3.10 release by selecting "local code updtes" from the left-hand flap. Be sure to save your image first! You can update a 3.9 image this way, but the more you have in your image, the less likely it is to work. Updating a 3.10 image will be much more likely to work.
