I just updated my version of Chrome to 0.2.149.30. Surprisingly it doesn't come with a "new release detector", so you will have to go to tools button and them choose "about google chrome" and then it will detect it's outdated and you can press in the link to upgrade.
I had posted before with my first impressions of my first week using google chrome:http://echofloripa.blogspot.com/2008/09/google-chrome-7-days-after-updated.html
I could notice that the problem with the link was solved. Also the mouse wheel problem now seems to be solved as well. But still the lack of add-ons is really annoying.
What I see as a problem is the lack of a release notes with the changes made to this new version. Is it or not an open-source software? It should come with a proper release notes of the major changes made.
 Just found out that there is a blog with the release notes. Why google doesn't make our lives easier putting a link in the download page or in the official google blog, I don't know :)
 Aparently they've made some improvement for the "on-demand installation".
 Just found another problem, if you are inside a text box and try to select with the left button and use the mouse wheel (to go down or up and continuing to select) it doesn't work.
