Breaking changes

• Upgrade to Spring Boot 3 RC2
  Commit · Pull request

  As Spring Boot now uses Tomcat 10.1, we cannot mix Jetty 11 (servlet 5) and Tomcat 10.1 (servlet 6) in the same test modules so they are all run with Jetty 11 for now.

• Require Node 18 (npm 8.6)
  Commit · Pull request

  Node 18 is the latest LTS version and what everbody should at least have going forward

• Enable auto update of installed Node by default
  Commit · Pull request

  This makes Flow keep its installed Node version up to date. Manually installed node versions are not affected

• Extract addon files to frontend/generated/jar-resources instead of a fake npm package
  Commit · Pull request · Issue

  No longer creates target/flow-frontend so any tool or script relying on that needs to be updated

New features

• Add polymer2lit converter
  Commit · Pull request · Issue

  Introduces a mvn vaadin:convert-polymer Maven command that converts Polymer-based source files into Lit. The following arguments are supported:
  -Dvaadin.useLit1 forces the converter to use lit-element rather than lit imports.
  -Dvaadin.disableOptionalChaining disables the usage of the optional chaining operator which can be helpful for projects still based on Webpack.
  -Dvaadin.path=/path/to/directory/or/file allows specifying the path to a file or directory that needs to be converted. By default, the converter scans all **/.js and **/.java files in the project.
  Note: When testing this command in the Flow repo, run the command mvn flow:convert-polymer instead.

• Add Gradle support for polymer2lit
  Commit · Pull request

  Adds a ./gradlew vaadinConvertPolymer Gradle task that converts Polymer-based sources to Lit. The following parameters are supported:
  -Dvaadin.useLit1 forces the converter to use lit-element rather than lit imports.
  -Dvaadin.disableOptionalChaining disables the usage of the optional chaining operator which can be helpful for projects still based on Webpack.
  -Dvaadin.path=/path/to/directory/or/file allows specifying the path to a file or directory that needs to be converted. By default, the converter scans all **/.js and **/.java files in the project.

• Basics for Spring native support
  Commit · Pull request

  This is the foundation to make Spring native work. It does not cover dynamic use like Route classes.

Fixes

• Add a default value to expressions when optional chaining is enabled
  Commit · Pull request

  The PR makes the converter add a default value to expressions that are built with the optional chaining operator. Before, the converter used to add a default value only in the case optional chaining was disabled. A follow-up to #14972

• Prevent adding an extra dot to expressions consisting of one non-null variable
  Commit · Pull request

  This PR prevents adding an extra dot to expressions that consist of only one variable that is assumed to never be null. This could occur before when running the converter with the enabled optional chaining operator. A follow-up to #14972

• Skip IBMRestServlet when checking for VaadinServlet
  Commit · Pull request · Issue

• Do not log null if servlet deployer is disabled
  Commit · Pull request · Issue

• Interpret a directory import as an import for index.js in the directory
  Commit · Pull request · Issue

  This is only used by the theme import rewriter which traverses all imports. It does not actually affect which files are imported
