Oracle data sources now connect through the pure-Rust oracledb thin driver (pinned to 26.0.0-beta.5) instead of ODPI-C, so no Oracle Instant Client, ORACLE_HOME or Instant Client setting is needed; TNS descriptors and tnsnames.ora aliases still work in the Database field. The database tree gains a packages folder for Oracle schemas, and a package's DDL opens as its specification and body. The database guide's Oracle section is rewritten for the thin driver.
