## ♫ Sound Behind The Release ♭
I figured, why not share one of the tunes I was spinning when powering thru teh bugs? Might as well share the pain/pleasure while viewing this release notes!

Contrarily to popular belief, OSS is not free! We've now reached ~9k stars and 300k downloads! As you all know, this project is not pimped out by a big company with deep pockets or a large team. K9s is complex and does demand a lot of my time. So if this tool is useful to you or your organization and part of your daily Kubernetes lifecycle, please contribute! Your contribution whether financial, PRs, issues or shout-outs on social/blogs are crucial to keep K9s growing and powerful for all of us. Don't let OSS by individual contributors become an oxymoron!
## Full Screen
We've added a new option to enable full screen while describing or viewing a resource YAML namely `f`. This works similarly to the full screen toggle option while viewing logs ie pressing `f` will toggle fullscreen on/off.

## Best Effort... Not!
In this drop, we've added 2 new columns to the Pod/Container views namely `CPU(R:L)` and `MEM(R:L)`. These represents the current request/limit resources specified at either the pod or container level. While in Pod view, you will need to use the wide command `Ctrl-W` to see the resources set at the pod level or you can use K9s column customization feature to volunteer them by default.

While in Pod view, you will need to use the wide command `Ctrl-W` to see the resources set at the pod level or you can leverage K9s column customization feature to volunteer them while in Pod view. In the Container view these columns will be available by default.
## Container Images
You have now the ability to tweak your container images for experimentation, using the new SetImage binding aka `i`. This feature is available for standalone pods, deployments, sts and ds. With a resource selected, pressing `i` will provision an edit dialog listing all init/container images.
You have now the ability to tweak your container images for experimentation, using the new SetImage binding aka `i`. This feature is available for unmanaged pods, deployments, sts and ds. With a resource selected, pressing `i` will provision an edit dialog listing all init/container images.
NOTE! This is a one shot commands applied directly against your cluster and won't survive a new resource deployment.
Big `ATTA Boy!` in effect to [Antoine Méausoone](https://github.com/Ameausoone) for putting forth the effort to make this feature available to all of us!!
## Crumbs On, Crumbs Off, Caterpillar
We've added a new configuration to turn off the crumbs via `crumbsLess` configuration option. You can also toggle the crumbs via the new key option `C`. You can enable/disable this option in your ~/.k9s/config.yml or via command line using `--crumbsless` flag.
```yaml
k9s:
refreshRate: 2
headless: false
crumbsless: false
readOnly: true
...
```
## FILTER...NOT!
Some folks have voiced the desire to use inverse filters while filtering to content in the resource table views. There is now a new filter option available when performing these filtering operations. For example, in order to see all pods that are not named `fred` you can now use `/!fred` as your filtering command.
## Disturbance In the Keyboard Force...
In this drop we've changed the key binding to toggle the header from `Ctrl-E` to `H`
