+# v1.0-4
+
+## Summary
+
+### Features 
+
+- cta-admin tapefile ls command: list the tape files located in a specific tape
+- New schema verification tool (cta-catalogue-schema-verify)
+- New tape statistic updater tool (cta-statistics-update)
+- TODO : New features ?
+
+### Modifications
+
+- Backward-compatible Catalogue schema changes:
+  - CTA_CATALOGUE table contains a status that can be 'UPGRADING' or 'PRODUCTION'. If the status is UPGRADING, the columns NEXT_SCHEMA_VERSION_MAJOR and NEXT_SCHEMA_VERSION_MINOR will contain the future version number of the schema.
+  - INDEXES and CONSTRAINT renaming to follow the [naming convention](https://eoscta.docs.cern.ch/catalogue/naming_convention/)
+  - UNIQUE CONSTRAINT on ARCHIVE_ROUTE (UNIQUE(STORAGE_CLASS_ID, TAPE_POOL_ID))
+  - Creation of an INDEX ARCHIVE_FILE_DFI_IDX on ARCHIVE_FILE(DISK_FILE_ID)
+  - Added 3 columns to the TAPE table : NB_MASTER_FILES, MASTER_DATA_IN_BYTES, DIRTY
+
+### Bug fixes
+
+- The scheduler does not return a mount if a tape is disabled (unless if the tape is repacked with the --disabledtape flag set)
+
+### Improvements 
+
+- CASTOR-To-CTA migration improvements
+
+## Package changes
+
+TODO: put the versions of EOS, XRootD, and Oracle versions with which CTA is compiled against
+
+## Upgrade Instructions from v1.0-3
+
+### 1. Upgrade the Catalogue schema version from version 1.0 to 1.1
+
+Before updating CTA, the Catalogue schema should be upgraded. Here is the link to the documentation about the database schema updating procedure : [https://eoscta.docs.cern.ch/catalogue/upgrade/](https://eoscta.docs.cern.ch/catalogue/upgrade/)
+
+The liquibase changeLog file is already done so you can directly run the [*liquibase update*](https://eoscta.docs.cern.ch/catalogue/upgrade/backward_compatible_upgrades/#3-run-the-liquibase-updatesql-command) command with the changeLogFile located in the directory *CTA/catalogue/migrations/liquibase/oracle/1.0to1.1.sql*.
+
+### 2. Update CTA components
+
+TODO : Instructions about how to update the tapeservers and the frontend.
