wavetermdev/waveterm v0.14.4-beta.2 on GitHub

Wave v0.14.4 introduces vertical tabs, upgrades to xterm.js v6, and includes a collection of bug fixes and internal improvements.

Vertical Tab Bar:

New Vertical Tab Bar Option - Tabs can now be displayed vertically along the side of the window, giving you more horizontal space and easier access to tabs when you have many open. Toggle between horizontal and vertical tab layouts in settings.

Terminal Improvements:

xterm.js v6.0.0 Upgrade - Upgraded to the latest xterm.js v6, bringing improved terminal compatibility and rendering. This should resolve various terminal rendering quirks observed with tools like Claude Code.

Other Changes:

backgrounds.json - Renamed presets/bg.json to backgrounds.json and moved background config to new tab:background key (auto-migrated on startup)
Config Errors Moved - Config errors removed from the tab bar and moved to Settings / WaveConfig view for less clutter
Warn on Unsaved Changes - WaveConfig view now warns before discarding unsaved changes
Stream Performance - Migrated file streaming to new modern interface with flow control, fixing a large time-to-first-byte streaming bug
macOS First Click - Improved first-click handling on macOS (cancel the click but properly set block/WaveAI focus)
Deprecated legacy AI widget has been removed
[bugfix] Fixed focus bug for newly created blocks
Electron upgraded to v41
Package updates and dependency upgrades
