I notice that GNS3 v0.8.7-2 was installed on Ubuntu via sudo apt install gns3 instead of the new version which is GNS3 v2.1.20 as this question is asked.
May I know why Ubuntu still using the old version of GNS3 in it's repository?

Description: Graphical Network Simulator
GNS3 is a graphical network simulator that allows simulation of
complex networks and to launch simulations on them. It is an excellent
complementary tool to real labs for administrators of Cisco networks
or people wanting to pass their CCNA, CCNP, CCIP or CCIE certifications.
It can also be used to experiment with features of Cisco IOS or to check
configurations that need to be deployed later on real routers.
.
You may configure devices ranging from Cisco routers, Cisco PIX firewalls,
Cisco ASA Firewalls, Cisco IDS to JunOS routers using Qemu or Pemu. GNS3
uses dynamips as an emulation back end, an IOS emulator which allows users
to run IOS binary images from Cisco Systems.
.
Cisco IOS, PIX, ASA or JunOS software images are not included.

I know I can get the latest version by updating the repo and install it as follows.
sudo add-apt-repository ppa:gns3/ppa
sudo apt-get update
sudo apt-get install gns3-gui
I just want to know why Ubuntu didn't use the latest version of GNS3 by default?
