Code Igniter,the open source PHP framework that I use to build JungleDragon, has been updated to version 1.7.0. Since I'm still in an early phase of development, I decided to upgrade JungleDragon with the latest version of the framework. Although not completely pain-free, the upgrade was doable:

• First, I simply replaced the core framework files of JungleDragon with the core framework files of CodeIgniter 1.7.0.
• Next, I had to reapply two patches that I made to the core files.
  
  • The first one concerns a bug in nested transactions. It seems to not have been fixed in 1.7.0., so I have to reapply it.
  • The second patch is JungleDragon-specific, where I have altered the Session library to be able to remember a session if the user selects "remember me?" when logging in.
• Finally, I had to rewrite my validation code to make use of the new Form Validation class of Code Igniter. The new class has some great improvements which result in less validation code.
