(Same applies to CCSv5)
[quote user="Gaston_Melo_Arg"]I have a lot of programs in CCSv3.3, they can be opened by this new releases?[/quote]
The CCSv5 project format is different but v5 will automatically convert v3 projects to v5 format when you open it in v5.
[quote user="Gaston_Melo_Arg"]If I'm going to purchase CCSv3.3, this will be the last version? which one is it? will be released new patches or upgrades?[/quote]
The last update to v3.3 was over 3 years ago (3.3.83.20). v3.3 is no longer supported. There will be no upgrades to it.
To purchase v3.3, you will need to purchase a v5 license. When you purchase a v5 license, you can use the same license with CCSv3, v4 and v5.
Thanks
