All healthy distributions will have either a `Changes` file, or a `ChangeLog` file. Sometimes authors also leave older versions on CPAN, and you can scan through them. Example: Module::Starter. Many currently-maintained modules have public repositories such as a Github repo, or a Subversion repo. Example: The Module::Starter Github repo. Backpan maintains practically all versions of all past CPAN releases. There's The Gitpan Project, which has a pretty good Git history for almost all CPAN modules that were in existence about three years ago. That project was assembled a few years back, and hasn't been updated. But if you want to look at really old diffs, it's there. If you have a specific need that isn't covered here, email the module's author and ask him if he's got what you need. Dave	[reply] [d/l] [select]

Usually the Changes file lists such things. Listed in 'Special Files' on the module page.	[reply]

peek() has been in Thread::Queue since version 2.01, based on the results of this: `cpan-listchanges --all Thread::Queue` [download] See: cpan-listchanges.	[reply] [d/l]

Permalink that points to the latest release and will still work when v3.02 is deleted: http://search.cpan.org/dist/Thread-Queue/Changes	[reply]

There's also a diff utility, though it may only be able to use versions the author hasn't deleted. Just another Perler interested in Algol Programming.	[reply]
