# Polish & Improvements - December 2024
> December 2024: multiple VCS agents, GitLab access token auth, Terragrunt cost estimation, Vault certificate auth, and deployment filtering by user and status.
This month, we've rolled out several updates and improvements to enhance workflows, address common challenges, and bring new capabilities based on user feedback. Here's a quick look at what's new.
## Improved Self-Hosted VCS Management
With the latest update to managing self-hosted VCS, we've introduced two key improvements:
### Support for Multiple VCS Agents
Manage multiple VCS Agents (Proxies) within the same organization. This enhancement allows routing requests to different servers, providing greater flexibility for distributed systems and workload-specific setups.
### Centralized Configuration in the UI
Use the Agents tab in Organization Settings to configure a self-hosted VCS connection once, assign a VCS agent key, and reuse it across templates and environments. This streamlines management and eliminates redundant configurations.
When creating a new template or VCS environment, the repository URL selection is now available as a dropdown list instead of a free-text field, allowing you to select a repository defined in the VCS Connections list, or add a new one.
These updates make it easier to scale and manage VCS connections efficiently.
For more information, visit the updated [Documentation on Managing Self-Hosted VCS](/guides/admin-guide/templates/self-hosted-vcs).
## Vault Authentication via Certificates
We've added support for Vault authentication via certificates in env zero's [Secrets](/guides/admin-guide/variables#secrets) in Self-Hosted Agent. This enhancement ensures secure, secure access to Vault-managed secrets using certificate-based authentication for improved security and easier integration with your existing PKI infrastructure.

## GitLab Personal & Group Access Token Support
We now support GitLab integration using [Personal](https://docs.gitlab.com/ee/user/profile/personal_access_tokens.html) or [Group](https://docs.gitlab.com/ee/user/group/settings/group_access_tokens.html) Access Tokens, making permission management more flexible and efficient.
When setting up a new Environment or Template, you'll see GitLab Access Token as an authentication option alongside OAuth.

## Cost Estimation for Terragrunt Run-All
You can now set up cost estimation for Terragrunt run-all executions. env zero uses Infracost to perform cost evaluation on each of the generated plans and combine them together. [Learn more](/guides/policies-governance/cost-estimation)
## Filter Deployments by User and Status
You can now filter deployments by status or by user that started the deployment.
## Filter Environments from the Summary Chart
Clicking any part of the Environments donut chart in the Summary Dashboard will now filter the Environment table below according to the selected Environment Status, making it easier to drill down into relevant data.
## Global Search by Environment ID
Our Global Search (CMD/CTRL + K) now supports searching by Environment ID, making it easier to immediately navigate to a specific environment you'd like to take a look at.
