# Release Notes 2.9

Next to these Release Notes a**more end user oriented article explaining all new functions**can be found here**in [German](https://eblocker.org/de/magazin/eblockeros-2-9-neuerungen/) and [English](https://eblocker.org/magazine/eblockeros-2-9-new-developments/).**

## eBlockerOS 2.9.1: April 21st 2022

With this maintenance release we have focused to improve several annoyances and glitches in the background. We've also improved the user interface and improved the overall security of the system.

**Attention white cube users:**With eBlockerOS 2.9 we have updated the linux kernel (integral part of the operation system). This update unfortunately **breaks the functionality of the color LED** only a few white cube eBlockers have build-in. This update will result the LED to permanently light up in white or blue. Unfortunately we can not fix this issue at our end and need to wait for a future kernel release. In case you are annoyed by the LED light, you can simply remove the LED without harm: Just open the case by pressing firmly to the left/right side of the eBlocker and lift the lid. The LED is set on a separate board with post connectors that can be simply pulled out.

### Thanks to the Team

### **eBlockerOS 2.9 Highlights & Changes**

- **Added**new beta technology to eliminate tracking parameters in links (i.e. links in newsletters are sanitized from tracking components)
- **Added**a new feedback link to user defined Trusted Apps so they can be shared more easily with eBlocker
- **Improved** the user interface in several ways: new Backup tab to save settings (System > Backup), moved Reset License to "License & Update", new Auto Trust App on/off switch under HTTPS
- **Improved**Several small eBlocker Doctor improvements (i.e. show a warning if no admin password has been set, better doctor texts, etc.).
- **Improved**eBlocker's firewall to block external Internet access (i.e. no access to eBlocker is granted if eBlocker is accidentally set up as "Internet exposed host")
- **Improved**accuracy of Auto Trust App, so even more native apps are added correctly
- **Improved**recognition of EasyList pattern to avoid overblocking even better
- **Improved**backup & restore of settings to include eBlocker's HTTPS certificate/key (encrypted by password) to ease migration
- **Improved**and updated the cloaked device user agents to hide better in the mass
- **Improved**security by updating all components used. This includes a linux kernel update which unfortunately breaks the LED control (see above for more details)
