| − | * As updates are made available to a development or stable release, the time it takes for an instance of that image to update itself increases.
| + | |
| − | * There is no way to change the default kernel (aki) and ramdisk (ari) associated with a AMI. Instead, you have to publish a new AMI each time a new kernel or ramdisk is available.
| + | |
| − | * When starting an instance, the user *can* choose a different kernel and ramdisk than the default associated with the ami.

| − | === Stable Releases ===
| + | |
| − | EC2 kernels and ramdisks will be released when kernel updates are done. For example, each time a new version of linux-image is released, a new aki and ami will be released.

| − | Release of a new AKI and ARI will not dictate release of a new AMI. Users can find the newest AKI and ARI for a given AMI release by utilizing the currency function discussed below.

| − | === Development Releases ===
| + | |
| − | Kernels and ramdisks for development releases will be released when the corresponding AMIs are released.

| − | At the time of publish, AMIs will be associated with the latest AKI/ARI that is available.
| + | |
| − | === Development Releases ===
| + | |
| − | Development releases will regularly update the AMIs. Each AMI published will reference the latest AKI/ARI available at the time.

| − | == Support Life Time ==
| + | |
| − | The release policy above will apply to EC2 images for the same time frame that is applied to other Ubuntu Server releases. That is 5 years for LTS releases, and 18 months for other releases.
