+# Releases stay pre-releases, which Lithe Store's tracker skips, for these
 # reasons:
 #   1. Lithe still bundles Java Support under the old ID
 #      dev.lithe.plugin.java-support.
-#   2. Current Lithe hosts reserve languageServers[].hostIntegration (the JDT
-#      integration) to dev.lithe.* plugin IDs and accept the short tool ID
-#      "java" only from verified official provenance, so they reject this
-#      package.
-#   3. The backend links Rust plugin SDK 0.2.0, which requires the host to
-#      offer litheLogging 1 and refuses to start without it. Only the latest
-#      Lithe preview offers it so far; no stable Lithe does.
+#   2. The package declares the Rust backend (backend 2), plugin-owned
+#      language server sessions (languageServers 3, requestMethods and
+#      commands) and plugin functions (pluginFunctions 1), and the backend
+#      links the Rust plugin SDK 0.3.0 (plugin function protocol 4). A host
+#      that predates the Lithe changes #1745 and #1746 does not offer them and

+#      no stable Lithe does. The SDK also requires the host to offer
+#      litheLogging 1 and refuses to start without it.
+#   3. The Maven and Gradle project templates have moved to lithe-plugin-maven
+#      and lithe-plugin-gradle. Until those plugins carry them, a release
+#      would drop the Maven and Gradle choices from New Project.
