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 https://developer.salesforce.com/releases, 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.

There is a What’s New in Salesforce? help article that has links to the older PDFs.

Not Released

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

Matching Releases to API versions

You can use /services/data/ to get XML that links from the release name to the API version from Winter '11 onward. [Source]

You can always find the list here: https://help.salesforce.com/apex/HTViewHelpDoc?id=whats_new.htm&language=en_US

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


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

You can check using the below link: https://developer.salesforce.com/search?q=release%20notes&language=en
