I want to update my LibreOffice (whole package). Is there a way to do it without uninstalling old and then installing new? If there is no option for updating directly, how should I do it otherwise? P.S. I don't want to keep the old version.
The PPA mentioned by jbuch14 is bleeding edge and not for you if you just want the 4.3 LibreOffice release.
For that, use
This leaves you stuck on 4.3 until you decide to switch in a new repo and repeat this process but it will ensure you get all the release quality 4.3 updates without risking loading in libreoffice alpha or beta code.

I just updated LibreOffice 4.2 to 4.3 myself (Ubuntu 14.04.1 LTS), following those instructions. Contrary to a lot of misleading information on the web, it is really totally simple and you do not have to remove anything or delete your customizations etc. So to upgrade 4.2 to 4.3 while keeping all your settings all you have to do is:
$ sudo apt-get install python-software-properties
Then check out the PPA for very latest version of LibreOffice: https://launchpad.net/~libreoffice/+archive/ppa (below is for 4.3)
$ sudo add-apt-repository ppa:libreoffice/libreoffice-4-3
$ sudo apt-get update
$ sudo apt-get install libreoffice
