[TYPO3-english] documentation: "inside TYPO3"

[Roland]

hi everybody,

i just started to read "inside TYPO3" at http://bit.ly/8CYD1z - and wonder
if there is a more uptodate resource covering the same topic? online or
offline. german or english. or is it still current enough? i am thinking
about e.g. the caching framework, the workspace and localization, where
there has been a lot of changes since 2008 if i am right. maybe there is a
reworked "inside TYPO3" planned for the T3O relaunch?

kind regards

roland
