The commit upgrades the application to React 19.2 and refreshes the surrounding toolchain to newer compatible versions, including React DOM, Redux Toolkit, Vite, TypeScript, ESLint, and Vitest. It also moves the routing stack from the older React Router line to v7, which brings API and behavior changes in navigation and route handling. The build and CI environment are updated as well, with the pipeline switching to Node 22 and the dependency graph modernized to match newer package requirements.

Jenkins Migration to Java 25 LTS

My Turnkey Jenkins LXC stopped updates via apt a month ago, so I had to update the key:

curl -fsSL https://pkg.jenkins.io/debian/jenkins.io-2026.key | sudo tee /usr/share/keyrings/jenkins-keyring.asc > /dev/null

And to update the repository:

echo "deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian-stable binary/" | sudo tee /etc/apt/sources.list.d/jenkins.list

Also, Jenkins needs Java 21 or higher. Installing it via deb package (Zulu):

sudo dpkg -i zulu25.32.17-ca-jdk25.0.2-linux_amd64.deb

In case any dependencies are missing, install them:

sudo apt --fix-broken install -y

Finally, fix the jenkins service path:

nano /lib/systemd/system/jenkins.service

Change

ExecStart=/usr/bin/java -jar /usr/share/jenkins/jenkins.war`

to

ExecStart=/usr/bin/java -jar /usr/share/java/jenkins.war

Reload systemd:

sudo systemctl daemon-reload

Clematis Desktop Plugins Installer

The next update for Clematis Desktop includes a new version of Runtime Manager UI plugin enriched with plugin downloader and installer, plus some more JVM monitors with GC marks.

There are many ideas yet to be implemented; the current list of changes is as follows:

  1. Removed Kiwi Plugin 'expected' type.
  2. Kiwi Plugin type control: ANY type can be loaded as SYSTEM or USER types of plugins, otherwise the types have to match
  3. Replaced the plugin list with the plugin table in Runtime Manager UI
  4. Fixed Kiwi Plugin classloader resource bundle issue
  5. Improved layout of the monitors' section
  6. Improved layout of the tabbed pane
  7. New type of UI extension shells that are loaded as USER plugins but are common for all users. Their lifecycle is slightly different from the one of SYSTEM plugins, since these shells are being destroyed at the end of each user session.
  8. Plugin download from a URL and automatic installation afterward
  9. Plugin uninstallation buttons
  10. New log panel component
