v1.11.0

A dependency-refresh release on top of 1.10.0 that also reworks how make versions reports dependency updates. There are no DSL, content, or runtime source changes. Existing Content.kt definitions compile and run unchanged, and the build still targets JDK 25. The minor-version bump reflects the readingbat-core minor bump, the core-utils major-version jump, and the new make versions-all target.

Highlights

• make versions lists only what is behind. A custom outputFormatter on DependencyUpdatesTask (in configureVersions() in build.gradle.kts) replaces the plugin's report. It prints one line per outdated dependency (group:name current -> latest), a ? line for each dependency that could not be checked, a line for a newer Gradle release, and All dependencies are up to date when nothing is behind. The existing pre-release filter is unchanged.
• New make versions-all target. It runs the same task with --output-formatter=plain to get the plugin's full report, which also lists every up-to-date dependency. Only this target writes build/dependencyUpdates/report.txt now.
• readingbat-core / readingbat-kotest 3.4.0 → 3.5.0. A minor bump; no call-site changes were required. correctAnswers() is still a suspend function, so ContentTests.kt keeps its runBlocking { … } wrapper.
• core-utils 3.2.2 → 5.1.1. This is two major versions. Content.kt (FileSystemSource, GitHubRepo, OwnerType) and ContentTests.kt (toDoubleQuoted) compile unchanged. readingbat-core 3.5.0 itself moved to the common-utils 5.1.1 line, so the whole runtime classpath agrees on 5.1.1 and no conflict resolution is involved.
• Kotlin 2.4.10 → 2.4.21. A patch bump. The -Xreturn-value-checker=check compiler flag on compileKotlin still reports nothing.
• Gradle 9.7.1 → 9.8.1. The wrapper jar, gradle-wrapper.properties, gradlew.bat, and the gradle-wrapper catalog key all moved together via make upgrade-wrapper. The configuration cache still stores and reuses entries.
• ben-manes versions plugin 0.64.0 → 0.66.0.
• Gradle daemon JVM args. gradle.properties now sets org.gradle.jvmargs to give the Gradle and Kotlin daemons a 4 GB heap, write a heap dump on OutOfMemoryError, and use UTF-8 file encoding.
• Docs refreshed. CHANGELOG.md and RELEASE_NOTES.md gained 1.11.0 entries, llms.txt picked up the new Gradle, readingbat-core, and core-utils versions and the new targets, and README.md / CLAUDE.md now document make versions and make versions-all.

Upgrade Notes

• No source changes are required for forks that track this template. This release touches only build.gradle.kts (the dependencyUpdates formatter), the Makefile, gradle/libs.versions.toml, gradle/wrapper/*, gradlew.bat, gradle.properties, and the docs.
• core-utils 5.1.1 removes or changes some public API, including ScopeFunctionsKt, SingleAssignVar.ThreadSafeSingleAssignVar, MiscFuncs.waitForPortAvailable (which now returns Boolean), toCreated(LocalDateTime), and the SecureObjectInputStream, NonNullableAtomicReferenceDelegate, and SingleSetAtomicReferenceDelegate constructors. This template uses none of them. Forks that call core-utils directly beyond what Content.kt uses should check their call sites against that list.
• The new org.gradle.jvmargs asks for a 4 GB daemon heap. On a machine with little memory, lower -Xmx in gradle.properties.
• Re-run ./gradlew --version after pulling so the new wrapper (9.8.1) downloads on first use.
• Under Gradle 9.8.1 every build prints "Deprecated Gradle features were used in this build, making it incompatible with Gradle 10". The cause is detekt 2.0.0-alpha.6 calling Configuration.setVisible(), which Gradle 9.8 deprecated and plans to remove in Gradle 11. It's harmless for now and should go away with a later detekt release.
• make versions no longer writes build/dependencyUpdates/report.txt. Use make versions-all if you rely on that file.
• JDK 25 is still required, unchanged since 1.8.0.
