Version 0.5.2

Bug Fix

This release fixes UI issues and memory consumption that was reported in #141.

Fixes

• Internal refactor to better manage locks
• Introduction of scrape timeout to avoid freeze
• Reduce the number of metrics to only store 8 metrics that ktop actually uses
• Add string interning for metrics label deduplication
• Reduce Prom MaxSamples to 50

Version 0.5.1

Bug Fix Release

This patch release fixes a critical startup hang that could occur when using Prometheus metrics.

Problem: ktop would sometime hang indefinitely when using Prometheus
metrics source and one or more nodes were slow or unresponsive.

Root Cause: The initial metrics collection blocked startup, waiting synchronously for
all nodes to respond. Sequential node scraping meant one slow node would block all others,
with no per-request timeout.

Solution:

• Test connectivity before starting collection (fails fast on RBAC issues)
• Non-blocking first collection with timeout
• Parallel node scraping instead of sequential
• Per-request timeout (30s) prevents indefinite blocking

Result: ktop now starts immediately and populates metrics in the background.

Version 0.5.0

v0.5.0 Release Notes

This is a massive release that updates ktop in several major ways. First, this release introduces Prometheus as a (default) metrics source, providing richer metrics and better accuracy when available. Second, the UI has been significantly enhanced with new detail views, improved navigation, and polished visualizations to make ktop a tool you can use daily to watch over your Kubernetes clusters.

What's Changed

New Features

• Prometheus Metrics Support - Native Prometheus scraping from kubelet, cAdvisor, and API server endpoints
• Prometheus as Default - Metrics source now defaults to Prometheus with graceful fallback
• Runtime Namespace Filtering - Filter pods by namespace at runtime
• Content Filtering - Search and filter content within views
• Column Sorting - Sort tables by clicking column headers
• Resource Detail Views - Drill-down detail pages for nodes, pods, and containers
• Context-Aware Navigation - Navigation hints adapt to current view
• Toast Notifications - User messages displayed via toast windows

Improvements

• Redesigned cluster summary panel
• Improved summary statistics display
• Enhanced health check reporting
• Enhanced sparkline visualizations
• Unified runtime storage backend for metrics
• Dynamic height adjustment on terminal resize

Documentation

• Updated documentation to reflect the new changes
• New GitHub Pages published at https://vladimirvivien.github.io/ktop/

Full Changelog: v0.4.1...v0.5.0

Version 0.4.1

This release is a minor release to fix how goreleaser configuration places Homebrew script in its default location.

Refer to release v0.4.0 for detail on major changes introduced in v0.4.0.

What's Changed

• Fix Homebrew cask placement by @vladimirvivien in #56

Full Changelog: v0.4.0...v0.4.1

Version 0.4.0

This release introduces new command-line options to filter which columns are displayed in nodes and pods tables.
Users can now customize the view by specifying columns with --node-columns and --pod-columns flags.

Column Filtering

You can now customize which columns are displayed in the nodes and pods tables. This is useful when you want to focus on specific metrics or when working with limited screen space.

To show only specific node columns:

ktop --node-columns NAME,CPU,MEM

To show only specific pod columns:

ktop --pod-columns NAMESPACE,POD,CPU,MEMORY

You can combine both filters:

ktop --node-columns NAME,CPU,MEM --pod-columns NAMESPACE,POD,STATUS

Available node columns:

NAME
STATUS
AGE
VERSION
INT/EXT IPs
OS/ARC
PODS/IMGs
DISK
CPU
MEM

Available pod columns:

NAMESPACE
POD
READY
STATUS
RESTARTS
AGE
VOLS
IP
NODE
CPU
MEMORY

These enhancements improve the usability and customization of ktop, allowing users to tailor the displayed information to their needs. The updated automation scripts also ensure a smoother release workflow.

Metrics-API informer

This minor release introduces an informer for the metrics-api types. This change should reduce api server chatter by caching metrics data and allowing ktop to perform better when clusters have large number of workload components.

Launching ktop via containers

The GitHub Action has been update to release ktop as an OCI container at ghcr.io/vladimirvivien/ktop. You can now run ktop as follows:

export KUBECONFIG=/home/user/.kube/config
docker run --network=host --rm --platform="linux/arm64" -it -v $KUBECONFIG:/config -e KUBECONFIG=/config -e TERM=xterm-256color ghcr.io/vladimirvivien/ktop:latest
