-# CHANGELOG
-This document summarizes main and fixes changes published in stable (aka `main`) branch of this project.
-Ongoing work and development releases are under `develop` branch.
-
-## 0.24.0
-
-### main features
-* ARM64 support -- Mizu is now available for ARM 64bit architecture
-  * Now you can run Mizu with `minikube` on your Apple M1 laptop or any other ARM-based hosts
-* New command helps user verify Mizu deployment
-  * Run `mizu check` to verify Mizu was deployed successfully
-  * `mizu check` verifies version compatibility, resources and permissions required by Mizu
-* EXPERIMENTAL: Service Map - graph of all service interactions
-  * Arrow direction show client to server connection
-  * Graph edge width reflects volume of traffic captured between the services
-  * to enable this experimental feature use `--set service-map=true` flag
-
-### improvements
-* Mizu container images are now served from [Docker Hub](https://hub.docker.com/r/up9inc/mizu), as multi-architecture images (arm64, amd64)
-* in Mizu GUI the filter query can now be applied by pressing CONTROL/COMMAND + ENTER
-* try port-forwarding if http-proxy connection to Mizu API server is not available
-
-### notable bug fixes
-* Fixed HTTP/1.0 presentation which was shown as HTTP/1.1
-* Fixed handling of long-living TCP connections, improves capturing gRPC and HTTP/2 traffic, and helps in service-mesh setups (istio, linkerd)
-
-
-## 0.23.0
-### notable bug fixes
-* fixed errors in Redis protocol parser (better handling of Array and Bulk String message types)
-
-
-
-## 0.22.0
-
-### main features
-* Service Mesh support -- mizu is now capable to tap mTLS traffic between pods connected by Istio service mesh
-  * Use `--service-mesh` option to enable this feature
-* New installation option - have the same Mizu functionality as long living pods in your cluster, with password protection
-  * To install use `mizu install` command
-  * To access use `mizu view` or `kubectl -n mizu port-forward svc/mizu-api-server`
-  * To uninstall run `mizu clean`
-* At first login
-  * Set admin password as prompted, use it to login to mizu later on.
-  * After login, user should select cluster namespaces to tap: by default all namespaces in the cluster are selected, user can select/unselect according to their needs. These settings are retained and can be modified at any time via Settings menu (cog icon on the top-right)
-
-
-### improvements
-* improved Mizu permissions/roles logic to support clusters with strict PodSecurityPolicy (PSP) -- see [PERMISSIONS](PERMISSIONS.md) doc for more details
- 
-### notable bug fixes
-* mizu now works properly when API service is exposed via HTTPS url
-* mizu now properly displays KAFKA message body 
-
-
-
-
-## 0.21.0
-
-### main features
-* New traffic search & stream exprience
-* Rich query language with full-text search capabilities on headers & body
-* Distinct live-streaming vs paging/browsing modes, all with filter applied
-
-### improvements
-* GUI - source and destination IP addresses & service names for each traffic item
-* GUI - Mizu health - display warning sign in top bar when not all requested pods are successfully tapped
-* GUI - pod tapping status reflected in the list (ok or problem)
-* Mizu telemetry - report platform type
-
-### fixes
-* Request duration and body size properly shown in GUI (instead of -1)
