Seth on Simulink

May 15th, 2008

Have you ever been in this situation: You run into a software bug, and you verify that the bug has been fixed in the latest version, but you can't install the latest version to get the bug fix. Why not? Because your team has a coordinated upgrade policy.

I often work with teams who have standardized on a specific release of Simulink. For them, rapid upgrading is not an option. With that in mind, if you can't upgrade to R2008a, I want to let you know that bug fixes to the R2007b versions of eight core Simulink family products are now available online.

Who can't upgrade?

While we always recommend that people upgrade to the latest version of Simulink, we realize this isn't possible for everyone. People in this situation are often part of large, extended teams, or they may be required to deliver models in a specific version to another company. While this is a nuisance in some ways, it can save a lot of trouble. For example, if people in the Widget Drive Train team take advantage of a brand new Simulink feature, then their colleagues in the Widget Engine Control Team who didn't install the new release may not be able to share work or integrate their models. This is why guidelines as simple as the specific version to use for a project are so important.

How do I find out when a bug is fixed?

MathWorks publishes bug reports (requires login) for all customer reported bugs.

If you have reported a bug, or discovered a bug report you are interested in, you can subscribe to that bug report to receive updates when anything changes.

You can even customize the bug reports to show only products and releases that you care about. This provides you with an RSS feed to which you may subscribe.

These updates can also be delivered daily, weekly or monthly to your e-mail inbox. Here are my subscription settings:

When the R2007b+ release went live for download, I received an e-mail notifying me the bug fixes.

Critical bugs fixed in R2007b+

The updates resolve key customer-reported issues in R2007b (which are also fixed in R2008a). Here are links to the bug reports for each product (requires login):

   Seth,

   Are ALL bugs reported by customers (or found by TMW) listed on the website? My personal experience with a recently-reported bug and subsequent dialog with a TMW support engineer suggested that only bugs deemed to affect a wide enough audience are listed.

   Seth,
   1. The Release pulldown list doesn’t include R2007b+ products. How did you get their URLs for your blog?

   2. How do access older versions of document at TMW web site?
