# Panfactum Changelog — edge.24-06-04

> Upgrades to devenv 1.0, improves Redis sentinel configuration, significantly speeds up devenv rebuilds on macOS, and fixes several issues with Karpenter autoscaling and ExternalDNS.

## Highlights

- Upgraded to devenv 1.0 — `.env` values can no longer be referenced directly inside `.nix` files
- macOS devenv rebuilds now 10-15x faster (from 10+ minutes down to ~45 seconds)
- Fixed Karpenter autoscaling issue when `extra_tags` was provided

## Breaking Changes

- Upgraded to devenv 1.0. As a part of this upgrade, `.env` file values can no longer be referenced directly inside

## Additions

- Updated [`kube_redis_sentinel`](https://panfactum.com/docs/edge/reference/infrastructure-modules/submodule/kubernetes/kube_redis_sentinel) to automatically limit client buffer size to prevent OOM issues when processing very bursty traffic.
  - Impacts: iac-module `kube_redis_sentinel` — Auto-limit client buffer size to prevent OOM issues
- Added `pf-update` command that runs all the repository scaffolding commands at once.

## Fixes

- Addressed an issue that caused updates to the local devenv to take at least 10 minutes to rebuild on macOS.
- Added missing defaults for `PF_ENVIRONMENTS_DIR` and `PF_IAC_DIR`.
- Resolves an issue where devenv warnings could not be resolved during the initial bootstrapping guide.
- Added extra validation for the terragrunt variable `extra_tags`. Invalid characters will now be replaced with `.` for both keys and
- Fixed core components that were using all Kubernetes labels for `labelSelector` matching rules, which prevented Karpenter from autoscaling when `extra_tags`

  - Reference (issue-report): [Too many label selectors preventing Karpenter scaling](https://github.com/Panfactum/stack/issues/46)
- Added extra constraints to [`kube_external_dns`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_external_dns) to prevent it from querying zones it isn't managing.
  - Impacts: iac-module `kube_external_dns` — Added constraints to prevent querying unmanaged zones
- Prevented [`kube_external_dns`](https://panfactum.com/docs/edge/reference/infrastructure-modules/direct/kubernetes/kube_external_dns) from excluding parent domains of included domains.
  - Impacts: iac-module `kube_external_dns` — Fixed exclusion of parent domains of included domains
