New and Noteworthy

UX improvements

Added Darklaf look and feel that improves several components.

Tree indentation level is easier to follow:

JMeter tree with Darklaf Darcula theme

JMeter tree with Darklaf IntelliJ theme

New look and feel themes. Light: IntellJ, Solarized Light, HighContrast Light. Dark: OneDark, Solarized Dark, HighContrast Dark.

When an element in tree is disabled, all its descendants are shown in gray. For instance, While Contoller is disabled in the following tree, so its children are gray. It is purely a UI change, and the behavior is not altered.

While controller is disabled, so its children are gray

Tree context menu is shown even in case the node selection is changed. Previously the popup did disappear and it was required to select a node first and only then launch popup.

Look and feel can now be updated without a restart

Use CTRL + ALT + wheel for zooming fonts. Previous shortcut was CTRL + SHIFT + wheel, however, it conflicted with horizontal scrolling.

In-app zoom is more consistent (e.g. sometimes not all the labels or even panels were scaled). For instance: log viewer, JSR223 code editor were not previously scaled with zoom-in/out feature

Tree context menu is shown for the full row, not for the label only

Undo and redo support for editable fields. Keystrokes are CTRL + Z / CTRL + SHIFT + Z, or CMD + Z/ CMD + SHIFT + Z depending on the operating system. Undo is implemented on a field level basis (each fields has its own history), and the history is invalidated when tree selection changes.

Mark the currently selected language in the options menu.

Mark the currently selected log level in the options menu.

Rework of many Test Element UI (JUnit Request, ForEach Controller, If Controller, Throughput Controller, WhileController, Counter Config, XPath2 Extractor, Function Helper Dialog, Search popup, JMS Elements)

Incompatible changes

• Default value of httpclient4.time_to_live has been modified from 2000 to 60000, this means HTTP connections will live longer than before. This has impact on connection creation and SSL handshake, see Bug 64289
