Redmine

I am checking up "Redmine" to change issue tracking system from "JIRA" to "Redmine".
But there are some problems for change.

I want to append some features as follows.

• allow the version field on an issue to assign multiple versions.
• add "affected version" field. (means which versions are affected by the issue)
• add "multiple select" custom field. (Feature #1189)

Our project management system like this.

 Core-Module (Package/Framework)
      |- Project A (customize for CustomerA)
      |- Project B (customize for CustomerB)
      |- ...

If I fix core-module, the issue has much effect on some projects. So I want you to support multiple select version field.

We can change to "Redmine" if there features include in version 0.9.
I want you to think about these features.
