in your pybombs directory or pybombs recipe directory run

git remote update
git pull

this should pull down any pybombs updates that may be available
you may want to 'git stash' before pulling and 'git stash pop' after if
you have any local changes.
or merge with a local branch with local modifications if you know what
you are doing

The 'safe' way to rebuild updated modules is to run
./pybombs update
this will
1. find any out of date packages - and all packages that depend on these
2. uninstall all of these packages for you
3. perform a fresh install of all of these packages

this may seem like overkill - but it is the only truly safe way to ensure
you can try the shortcut approach - which is to run

cd pybombs/src/gnuadio/
git remote update
git pull
cd build
make install

this is much much faster to do, it may not even need to run cmake if
changes were very minor
however - if you don't rebuild everything that links against gnuradio
there is a danger that you will break linkage or some API/ABI contract
with the dependent library, and there is always a danger that cmake
won't automatically re-generate some file that is is supposed to when
running this (like swig sources) - so when you do this you are rolling
the dice.
You may be able to get away with this a few times, but invariably one
day you will start running into strange seg-faults which seem
nonsensical, and which would completely go away in a fresh build.
The other safe thing is to just do a fresh pybombs build in a separate
directory so you don't lose your old working build while testing against
the latest versions of code from various repos.
