Log Buffer Limit (#932)

Added a configurable upper bound on the number of lines retained in the log view buffer to prevent unbounded memory growth during long log sessions.

• Config: logging.max_lines in ~/.config/kubetui/config.yaml
• Per-query override: limit:<n> (alias lim) keyword in the log query
• When the buffer exceeds the limit, the oldest lines are dropped first

logging:
  max_lines: 5000

pod:api log:error limit:1000

Namespace Fallback (#952)

Configurable list of namespaces to display when the Kubernetes API does not allow listing namespaces (e.g. RBAC restrictions). The namespace selector now falls back to the configured list with an indicator in the title.

fallback_namespaces:
  - production
  - staging
  - dev

Per-widget Error Display (#953, #956)

Reworked the way data-fetch errors are displayed in widgets. Previously, errors were shoehorned into each widget's data type — Table widgets had their header replaced with ERROR, and Log/List widgets had ANSI-colored error lines mixed into their content. The Tab/Dialog layer now manages widget error state separately and renders the error in place while preserving the widget's title and border. The view automatically reverts to the normal display when fresh data arrives. The display style is themable via theme.component.error.

theme:
  component:
    error:
      fg_color: red
      modifier: bold

What's Changed

Bug Fixes

• Workaround kube-rs not respecting NO_PROXY (#919) - Fixed an issue where the NO_PROXY environment variable was not being respected by kube-rs, causing requests to bypass proxy exclusion rules.

Features

OSC 52 Clipboard Support for Remote Sessions (#901)

Added OSC 52 escape sequence clipboard support for SSH/WSL/tmux/screen environments:

• New CLI option: --clipboard=auto|system|osc52 (default: auto)
• Environment variable: KUBETUI_CLIPBOARD
• Auto detection: Automatically uses OSC 52 when SSH session is detected (SSH_CONNECTION/SSH_CLIENT/SSH_TTY)
• Terminal-specific handling: Proper DCS wrapping for tmux and screen

tmux Configuration (tmux 3.3a+):

set -g allow-passthrough on
set -g set-clipboard on

Bug Fixes

• Defer initialization of inactive contexts to prevent startup crashes (#898) - Fixed an issue where kubetui would crash on startup if any non-selected context had authentication errors. Contexts are now initialized only when selected. Thanks @umegbewe!

What's New

Features

Drag-to-Scroll Text Selection (#880, #885)

Added tmux-like drag-to-scroll functionality for text selection in log views:

• Automatic scrolling at boundaries: When dragging text selection to the top or bottom edge (1st line or last line), the view automatically scrolls in that direction
• Continuous auto-scroll: When the mouse stops moving at boundaries, scrolling continues automatically every 200ms
• Expanding selection area: The selection range expands automatically during auto-scroll
• Horizontal scrolling support: Works for horizontal scrolling when text wrapping is disabled
• Performance optimized: Auto-scroll only processes the active widget

This enhancement makes it much easier to select and copy large portions of log data without multiple manual scroll operations.

Technical Details

• Uses existing Tick worker (200ms interval) for periodic updates
• Tracks dragging widget to continue event routing when cursor moves outside widget bounds
• Stores last mouse position and scroll direction for smooth auto-scroll behavior
