Is there a space matrix available for LEED V4?

The USGBC has not yet created a matrix for LEED v4, instead similar content was added to the reference guide, in the intro section or the EQ credit category.

Could you please advise when was the release date of the IEQ Space Matrix. Since I have a project which was registered on Dec 20th , 2011. I was wondering if this list would be applicable and mandatory in my submittal for IEQ 6.1.

The space matrix was first released in November 2011. From a procedural standpoint, the matrix is essentially an extension of the reference guide or guidance document. It was never published as a LEED Interpretation.
The existing FAQ I wrote earlier may also help:
Is the IEQ Space Matrix a Guidance Document or is it required?
If your project was registered after the release of the IEQ Space Matrix then LEED reviewers will expect you to use the matrix to help determine which spaces to include in various credit requirements. However, as is the case for all LEED credits, if you have an exceptional circumstance you can make a case in a narrative for why your project must take a path not outlined or clarified in the matrix.

Thank you for your prompt feedback. Another quick question please, are all the spaces in the aforementioned matrix to be included in the " shared multi-occupant spaces ' part of the credit ? i.e. the matrix doesn't segregate between areas applicable to the individual workstations parts of the credit against the shared multi-occupant spaces part. As the definition of the shared multi-occupant spaces as per the reference guide is " spaces including conference rooms, classrooms, and other indoor spaces used as a place of congregation." which differs from the definition stated in the matrix " places of congregation, or where occupants pursue overlapping or collaborative tasks. Multi occupant spaces may be regularly or non-regularly occupied spaces. ".
Thank you for your help ! :)

Not necessarily. The IEQ Matrix addresses both multi-occupant and individual occupant spaces. For instance, if you check out the "BD+C and ID+C Matrix" tab you'll see that under "Cells", for example, there is an indication that they are generally considered Individual Occ. Spaces.

Reviving a dead thread... Has USGBC updated the Space Matrix for v4? Lauren's response above references the intro section of the reference guide, but this isn't sufficient for defining Classroom and Core Learning Spaces for the Minimum Acoustic Performance Prerequisite. Classroom and Core Learning Spaces are no longer listed in the intro section like in previous versions (See pg. 404 of the v2009 Reference Guide). Step 1 of the v4 step-by-step guidance for the Minimum Acoustic Performance Prerequisite states to "see EQ Overview for a list of space types that are considered classrooms and other core learning spaces." this list just doesn't exist in the v4 version.
