VERSION_HISTORY CONSTANT VARCHAR2(4000) :=
'v2.12.0 (2026-02-24): CRITICAL FIX - Rewritten DELETE_FAILED_EXPORT_FILE to use file-specific pattern matching (prevents deleting parallel CSV chunks in shared folder). Added vQuery logging before DBMS_CLOUD calls. Added CSV maxfilesize logging.' || CHR(10) ||
'v2.11.0 (2026-02-18): Added pJobClass parameter to EXPORT_TABLE_DATA_BY_DATE and EXPORT_TABLE_DATA_TO_CSV_BY_DATE for Oracle Scheduler job class support (resource/priority management).' || CHR(10) ||
'v2.10.1 (2026-02-17): CRITICAL FIX - Remove redundant COMPLETED chunks deletion before parallel export that caused ORA-01403 errors (phantom chunks created by CREATE_CHUNKS_BY_NUMBER_COL).' || CHR(10) ||
'v2.10.0 (2026-02-13): CRITICAL FIX - Register ALL files created by DBMS_CLOUD.EXPORT_DATA (multi-file support due to Oracle parallel processing on large instances). Prevents orphaned files in rollback.' || CHR(10) ||
'v2.9.0 (2026-02-13): Added pProcessName parameter to EXPORT_TABLE_DATA and EXPORT_TABLE_DATA_TO_CSV_BY_DATE procedures for process tracking in A_SOURCE_FILE_RECEIVED table.' || CHR(10) ||
'v2.8.1 (2026-02-12): FIX query in EXPORT_TABLE_DATA - removed A_LOAD_HISTORY join to ensure single file output (simple SELECT).' || CHR(10);
'v2.9.0 (2026-02-13): Added pProcessName parameter to EXPORT_TABLE_DATA and EXPORT_TABLE_DATA_TO_CSV_BY_DATE procedures for process tracking in A_SOURCE_FILE_RECEIVED table.' || CHR(10);
