Unreleased

0.2.0 - 2026-10-20

Requires Java 25 and the Clojure CLI.

Added

• Layered weller.edn configuration files with deep merging and environment variable placeholders.
• Automatic CRAL configuration and Alfresco ticket validation and renewal through weller.config/ticket.
• Node path predicates supporting exact strings and regular expressions.
• remove-taps to stop a pipe and remove its processing taps.
• Clojure CLI aliases and tools.build tasks for packaging, local installation, and Clojars deployment.
• Interactive deploy.sh script for Clojars publishing.

Changed

• Use Java 25 for development, builds, and CI.
• Move make-tap from weller.predicates to weller.pipe.
• Allow filtered taps to be added to running pipes, starting their handlers immediately.
• Run JMS reception and message callbacks on blocking workers separate from the core.async go dispatch pool, preserving sequential processing within each handler.
• Replace Leiningen with Clojure CLI and tools.build, including CI and cljdoc preview scripts.
• Update Clojure to 1.12.6, ActiveMQ to 6.3.2, data.json to 2.5.2, CRAL to 0.3.5, core.async to 1.9.865, and Telemere to 1.4.0.
• Update the Docker development stack to ACS and Share 25.3.0, Search Services 2.0.17, and PostgreSQL 18, and increase Solr memory.
• Standardize GPL license headers with SPDX identifiers and copyright years.
• Expand configuration, development, build, and publishing documentation.

Fixed

• Wake and stop waiting message handlers through a dedicated stop channel, allowing restarts without leaving previous consumers active.
• Log and discard malformed JSON, non-object JSON values, and unsupported JMS message types without stopping the listener.
• Keep handlers processing subsequent messages after callback exceptions, without automatically retrying failed callbacks.
• Disconnect, close, and drain removed tap channels to release pending mult deliveries and prevent message distribution from stalling.

Removed

• Unused Component dependency and immuconf dependency.

0.1.0 - 2024-05-20

Added

• Initial Clojars release of org.saidone/weller, providing Alfresco out-of-process extensions in Clojure.
• ActiveMQ event listener and core.async message pipes with filtered processing taps.
• Composable predicates for Alfresco events and node resources.
• Component lifecycle operations for starting and stopping message processing.
• EDN configuration for Alfresco and ActiveMQ connections.
• Integration tests and a Docker-based Alfresco development environment.

This release was published to Clojars on 2024-05-20. Both the published POM's SCM tag and the JAR's pom.properties identify commit 7cc85880b396c334526afe769a2b516d2d82759b. The GitHub tag and release were added retrospectively for that exact commit.
