Changelog

3.5.0

• 🚀 Feature: Added support for Easy Connect Plus (ECP) URLs

3.4.5

• 🐛 Fix: Read connection pool size and max response size from the [plugin.grafana-oracle-datasource] grafana.ini section (forwarded as GF_PLUGIN_POOLSIZE and GF_PLUGIN_MAX_RESPONSE_SIZE). On Grafana 12.4.2 and later, host environment variables are no longer forwarded to plugin backend processes by default, so the previous GF_PLUGINS_ORACLE_DATASOURCE_POOLSIZE / GF_PLUGINS_ORACLE_DATASOURCE_MAX_RESPONSE_SIZE variables silently fell back to defaults. Those legacy variables are still read for backward compatibility.
