Bug Defect Tracking Question:

New: In finding an issue in testing, all relevant checks are performed, like whether is was occurring in the previous release. If the issue is so, reopening the bug and creating new defect is done by changing the status of that defect to ‘new’.

Open: When a new bug is opened, development or project manager revises it, followed by assigning the task to the developer, and changes the status from ‘new’ to ‘open’.
