If you want to stick with the .deb package, you have to wait until Michael made a new one (usually happens nearly every day).
Otherwise, you can of course simply checkout from svn and build your own, it is not hard.
Something like this should do just nicely:
sudo apt-get install libwxgtk2.6-0 libwxgtk2.6-dev wx2.6-headers wx-common
mkdir cb && cd cb
svn checkout svn://svn.berlios.de/codeblocks/trunk
cd src
./bootstrap && ./configure && make && sudo make install
It might be that you need to install gcc or automake, too, if those are not on your system (but normally they should be).
