As a follow on to the recently posted question "What are all of the reasons why Salesforce customers should upgrade the API version on their Apex classes, triggers, and pages?".

Where can I find all past Salesforce Release Notes, so I can review changes necessary to upgrade my Apex classes, triggers and pages to newer API versions?

I need notes all the way back as far as v18.0, other people may need to go back even further.

Going to, currently shows Summer '14 Release Preview. There is a link there to "Past Release: Spring '14" but that doesn't go anywhere and there is no link to all past releases that I can find.

I just spent like 10 minutes searching for it, and I just couldn't find it! I could have sworn there was a page that listed them all out, but the best I could find is… which only has the past 3. – Jesse Altman Jun 12 '14 at 19:18
Here are all Earlier Reference Docs However, these do not include Release Notes, ideally they would be listed here as well. – Alan Morey Jun 12 '14 at 19:20

Not Released

It turns out that Spring '05 and Spring '06 were not released. Hence--no release notes!

The above answer has all the links and it should be upvoted but isn't it easy to go to and search for release notes.

You can check using the below link:

You can always find the list here:

Should the link change in future searching for "past releases" should find it.
