What changed in JobRunr 9?
Job history becomes a timeline
JobRunr 9.0.0 adds a Chart tab to dashboard job history. It represents a job as a Gantt-style timeline, with rows showing state changes and durable steps. The feature is available in both the open-source and Pro editions. The JobRunr Team describes the goal as making background jobs less of a “black box”; that is product positioning, not an independent assessment of the dashboard.

Know which features are Pro-only
The vendor distinguishes the shared chart from paid capabilities. Job Analytics, controls to pause or resume a batch, and instant job starts on PostgreSQL are Pro features. The vendor’s release announcement does not make these features part of the open-source release.
Check compatibility before upgrading
Version 9 is the last open-source JobRunr release to support Java 8. The upgrade removes support for Micronaut 4, removes APIs deprecated in v8, and requires JDK 17 or later for test fixtures. JobRunr adds support for Micronaut 5 and Quarkus 3.40. Consult the project’s migration guidance before moving from v8, particularly if an application uses Micronaut 4 or deprecated APIs.
For Pro installations with large job tables, plan for the first startup after migration: database indexes are created during that migration, so startup work may be significant.
What’s new in OpenXava 8?
Modernized stack, with Java 17 as the minimum
OpenXava 8.0.0 defaults to Spring Boot 4.1 and supports Jakarta EE 11. Java 17 is now required; Java 8 and 11 are no longer supported. The release supports Jakarta Persistence 3.2 and drops JPA 2.2, supports Tomcat 11 and drops Tomcat 10, 9, and 8. A standard Jakarta EE 11 WAR remains supported, and generated WARs can run with java -jar.
Rank #2
UI and application-development changes
The project describes the release as a major modernization while retaining its simple-Java-class approach to application development and its existing entities, actions, and calculators. The UI has been redesigned with light, dark, and automatic themes. OpenXava also introduces a pure-Java UI generator and removes the legacy JSP renderer, alongside numerous dependency upgrades. Its announcement describes “more than 60 new features”; that is the project’s own count.

Existing applications should follow OpenXava’s migration instructions before upgrading. Configuration has moved into Spring Boot conventions, and older classes and properties have been removed, so a version change may require application-level edits rather than a simple dependency update.
Rank #3
Is Quarkus 3.40 an LTS release?
Yes. Quarkus announced 3.40 as a new LTS on September 30, 2026. The announcement says it is based on 3.39 and that Quarkus LTS releases receive 12 months of support.
Do not confuse 3.40 with the 3.34.0 fixes
The roundup separately reports bug fixes in Quarkus 3.34.0: improved AeshLauncher signal and timeout diagnostics, and removal of an unnecessary warning when a REST endpoint returns void. Those fixes belong to 3.34.0, not to the 3.40 LTS announcement.
What changed in Micronaut 5.2?
InfoQ reports Micronaut Framework 5.2.1 and 5.2.0, based on Micronaut Core 5.2.11 and 5.2.8, respectively. The reported additions include experimental compile-time processing of Python source through Micronaut for Python and a new Micronaut Jakarta EL module implementing Jakarta Expression Language. These release details are reported by InfoQ; they were not independently confirmed against Micronaut’s release announcements.

InfoQ reports that LangChain4j 1.21.0 includes bug fixes, dependency upgrades, and experimental decision-model APIs. The named components are DecisionModel, DecisionServices, RoutingChatModel, and DecisionRouterPlanner. Treat these APIs as experimental; the release summary does not establish production validation. The specific release notes and tutorial were not independently reviewed.

What does Eclipse JNoSQL 1.19.0 add?
According to InfoQ, Eclipse JNoSQL 1.19.0 adds ScyllaDB support and updates its drivers for Neo4j 6.3.0, InfluxDB 1.11.1, DynamoDB 2.55.7, and MongoDB 5.13.0. The roundup also reports improved lifecycle logging involving Oracle NoSQL and Jakarta Persistence extensions. It describes Eclipse JNoSQL as the compatible Jakarta NoSQL implementation and notes that the project moved from incubation to an Eclipse EE4J project. These release specifics are based on InfoQ’s account rather than an independent review of the release notes.
What changed in Google ADK for Java and Kotlin?
InfoQ reports separate updates for the two language SDKs:
- ADK for Java 1.11.0: adds
rewindBeforeInvocationId()and thread-safe session methodsimmutableEvents(),addEvent(), andaddEvents()as replacements for deprecatedevents(). - ADK for Kotlin 1.3.0: adds the
@ExperimentalLiveApiannotation for a live, bidirectional streaming API and changes event-author initialization fromnullto an empty string.
These details are attributed to InfoQ’s roundup; the project release announcements were not independently reviewed.
What is Lathe?
Lathe is a Java language server implementing the Language Server Protocol (LSP). InfoQ identifies Alexey Gavrilov, a senior software engineer at Telenor Linx, as its creator and reports version 0.1.14 as the latest release that week.
Its distinguishing approach is to derive editor project context from a Maven build model and keep that context synchronized, rather than relying on a traditional project import and manual classpath or module-path configuration. InfoQ says it works with LSP-compatible editors and ships with a Neovim client and an MCP server for AI coding agents. These Lathe details are based on the roundup’s account.
