Zend Framework Versions Overview

What are the mapping of CE/PE/EE versions to corresponding Zend versions?

If possible I need a list going back before Magento 1.1.

Here is what I have. I hope it's enough. Because PE and EE versions can be related to CE versions I think you can figure out the missing values.

CE 1.0.19870.4 - ZF 1.5.1
CE 1.1.6 - ZF 1.5.1
CE 1.2.0.1 - ZF 1.7.2
CE 1.3.2.1 - ZF 1.7.2
CE 1.4.0.1 - ZF 1.9.6
CE 1.4.2.0 - ZF 1.10.8
CE 1.5 - CE 1.8 - ZF 1.11.1
CE 1.9 - ZF 1.12.3
CE 1.9.1.2 - ZF 1.12.10

PE 1.10 - ZF 1.11.1
PE 1.11 - ZF 1.11.1

EE 1.9.1.1 - ZF 1.10.8
EE 1.10 - 1.13 - ZF 1.11.1 EE 1.14 - ZF 1.12.3

[EDIT]
To get the ZF version of your Magento instance look in the file lib/Zend/Version.php.
The class constant VERSION is what you are looking for.
