v2.1.0

Fixed

• Prevent SQLite sidecar crash on startup in multi-tenant applications due to trigger/index deployment running before tenant tables exist
• Invoke enhanceModel in after-deploy handler of cds.xt.DeploymentService because the loaded handler is not invoked on the tenant CSN from ModelProviderService.getCsn()
• Fix HDI deployment failure (sap.changelog.Changes_CT_INDEX.hdbindex requires db://SAP_CHANGELOG_CHANGES which is not provided by any file) caused by adding .hdbindex artifacts even when Changes table does not exist in the compiled model
• HDI deployment failure (invalid column name: CHANGEVIEW_0.PARENT_ENTITYKEY) during extensibility upgrades since enhanceModel was not called on the tenant CSN before HANA compilation
• Support model enhancement with xtended CSN flavor to support extensibility and feature toggle setups

v2.0.3

Fixed

• Skip trigger generation for localized text tables (*.texts)

v2.0.2

Fixed

• Fix <expr>.cds compilation error during cds deploy --to hana when expression-based @changelog annotations (CXL) are used as objectIDs on entities with compositions
• Prevent @PersonalData field values from leaking into objectID or valueChangedToLabel columns when @changelog annotations reference such fields via path expressions or CXL
• Fix missing cds.Composition parent entry and broken parent_ID links in generated triggers when a DB-level select * view of a parent entity inherits the same composition

v2.0.1

Fixed

• Resolve false "Conflicting @changelog annotations" error when a service projection flattens association and inherits plain true instead of a specific @changelog annotation value (e.g., [author.name]) due to CDS annotation propagation

v2.0.0

Added

• Trigger generation for SQLite, HANA, Postgres and H2 to perform change tracking on the database level
• Allow grouping of changes via new transactionID column
• valueChangedFromLabel and valueChangedToLabel columns on sap.changelog.Changes for localized labels
• Allow change tracking skip via session variables for entire transactions, entities, elements (ct.skip)
• Dynamic localized label lookup: if a @changelog label points to a localized property from a code list entity, the label is resolved in the reader's locale at read time
• Support CDS expression language (CXL) in @changelog annotations for custom objectIDs and changelog labels
• Customizable objectID for composition changelog entries on parent entities
• Support for tracked Date, DateTime, Time and Timestamp properties with correct formatting
• Support for @Common.Timezone on change-tracked entities
• Database indexes on sap.changelog.Changes for faster parent composition lookups and deduplication queries
• Generation of .hdbmigrationtable and updating undeploy.json via cds add change-tracking-migration
• HANA procedure SAP_CHANGELOG_RESTORE_BACKLINKS to restore parent-child hierarchy for composition changes

Changed

• Display changes with a Tree Table
• Changes from child entities are shown on the parent ChangeView by default (configurable via maxDisplayHierarchyDepth)
• Composition changelog entries on parents always have update as modification type
• Only skip change tracking for @PersonalData.IsPotentiallySensitive and @PersonalData.IsPotentiallyPersonal (not @PersonalData.FieldSemantics)
• Localization is performed on database level via sap.changelog.i18nKeys table
• Modifications on sap.changelog.Changes:
  • Removed serviceEntityPath, keys and foreign key changeLog
  • Renamed entityID to objectID
  • Added entityKey, createdAt and createdBy from deleted entity sap.changelog.ChangeLog
  • Added parent association and children composition
• Change History section is hidden in draft mode

Fixed

• Performance issues when working with entities that include a large number of fields and children
• Creation of changelogs at bulk operations
• Search and sort functionality on the ChangeView
• LargeString values are truncated and don't lead to failing inserts
• Explicit type casts for Date, DateTime, Time, Timestamp and Decimal fields in ChangeView
• Format tracked decimal values with correct precision (e.g., Decimal(11,4) stores 0 as 0.0000)
• ObjectID correctly falls back to entity key when all @changelog fields are NULL

Removed

• Event handler registration for change capture mechanism
• Entity sap.changelog.ChangeLog and flattened into sap.changelog.Changes
• Removed configuration option considerLocalizedValues
• Information about which service a change originated from

v2.0.0-beta.13

Changed

• Composition changelog entries on parents have always 'update' as modification type
• HANA triggers now use statement-level execution by default for improved bulk DML performance

Added

• Consider @Common.Timezone on entities that are change-tracked only via a service-level @changelog. Previously, valueTimeZone in ChangeView was resolved only for entities annotated with @changelog at the DB level
• rowLevelTriggers configuration flag to opt into legacy row-level HANA triggers as a workaround for "invalid RID address" errors

Fixed

• Migration table now correctly handles composite keys from v1 using HIERARCHY_COMPOSITE_ID (supports up to 5 key parts)
• @Capabilities.ReadRestrictions on ChangeView is now only applied when the view is auto-created by the plugin. Services that explicitly expose ChangeView allow direct read access.
• HDI deployment failure caused by adding .hdbindex artifacts even when Changes table does not exist in the compiled model

v1.2.2

Fixed

• Adjust MERGE SQL statement for migrating Changes and ChangeLog table in multitenant scenarios

v1.2.1

Fixed

• Removed @cds.persistence.journal annotation from Changes entity that caused deployment errors

v2.0.0-beta.12

Fixed

• Build crash when using @changelog path annotations on unmanaged associations due to missing guard on col.keys
• SQLite update trigger OF clause generates correct column names for unmanaged associations (e.g., assocName_fkField instead of fkField)
• SQLite association label lookup using the entity's primary key instead of the foreign key field in the where clause for unmanaged associations
• Deduplication of column names in update trigger OF clauses when a field is referenced by both a tracked element and an unmanaged association
• Prevent server crash when no db connection is available during session variable assignment

Added

• Optimization to skip unnecessary subselect lookups for unmanaged associations when the @changelog path references a target key that is already available as a local foreign key field

v2.0.0-beta.11

Added

• Database indexes for sap.changelog.Changes table on parent_ID for navigating the parent association hierarchy (SQLite, HANA, Postgres)

Fixed

• ChangeView in services is no longer directly accessible. Now it can only be accessed via the navigation paths
• Deployment error when an entity key uses a custom type defined as an association (e.g., type MyType : Association to SomeEntity) due to incorrect entityKey expression in the changes association mapping
• Runtime error when requesting ChangeView due to incorrect where clause for entities with association-typed keys in timezone column subselects
