This gets thrown around a lot, but it's not entirely true. Depending on the particular distro, only certain core packages are likely to get updates on LTS releases. Non-core packages may just get left to rot until the next LTS release. Specifically Ubuntu follows this. A lot of their non-core packages just get imported from Debian and then just sit unmaintained until next release (this goes doubly if not using Ubuntu Pro).
