The new Cisco Packet Tracer 6 looks pretty much the same as previous release 5.3.3, also still geared towards CCNA learning. I do still highly recommend using GNS3 which provides emulation instead of simulation.
Packet Tracer allows activity authoring for approximately 80% of the topics and skills required for CCNA Certification, and has relevance to CCNA-Security, CCNP, IT Essentials, and general TCP/IP courses as well. Although the program includes some sample activities, we strongly encourage you to share activities that you create with others in the CCNA teaching and learning community. In addition, integrated into the Discovery and Exploration courses are hundreds of already-written Packet Tracer activities.
The following have been highlighted as new from the previous version:
