HI AndrewD
I've just updated to 2.2.6 RC and I've noticed a couple of things ..
When viewing a single entry (if you've clicked a link from the vBa module as an example) the system still shows the subcats for the category the link is in. I would expect not to see this. (I've got a feeling this was in the older version of 2.2.6, but I've only just noticed it)
When viewing a Comments/ratings of an entry, if you have template_altbit set as "Modern" you still get the quick view dropdown - see screenshot (just seems silly to have both on that particular page

)
No other bugs to report at the moment ..
Suggestions:
Any chance of getting the above mentioned dropdown on the "Tabular" linkbit template?
Change the show_hit_parade template to look something like I have at
http://www.yaxleyvillage.com/local_links.php .. but without the dodgy final comma and the breaking up of multi worded entries
On the "Show" dropdown menu add a "Latest Comments" option - possibly add this sort of data to the Statistics admin page?
Add the ability to search comments on the Advanced Search page (third tickbox after title/description and keywords, but leave it unticked?)
I'll let you know if I think of anything else
