| If you plan to upgrade to v24.3 directly from v24.1 and skip v24.2, be sure to also review the [v24.2 release notes]({% link releases/v24.2.md %}) for backward-incompatible changes from v24.1. | ||
| - The old `BACKUP TO`, `RESTORE FROM <collectionURI>`, and `SHOW BACKUP IN <collectionURI>` syntaxes are now fully deprecated and no longer usable. [#133610][#133610] | ||
|
|
||
| - Upgrading to v24.3 is blocked if no [license]({% link v24.3/licensing-faqs.md %}) is installed, or if a trial/free license is installed with telemetry disabled. [#130576][#130576] | ||
| - Altering a paused backup schedule's recurrence or location no longer resumes the schedule. [#134829][#134829] | ||
|
|
||
| [#130576]: https://github.com/cockroachdb/cockroach/pull/130576 | ||

| - Introduced the `legacy_varchar_typing` session setting. If `on`, type checking and overload resolution for VARCHAR types ignore overloads that cause errors, allowing comparisons between VARCHAR and non-STRING-like placeholder values to execute successfully. If `off`, type checking of these comparisons is more strict and must be handled with explicit type casts. As of v25.1.0 this setting defaults to `off`. [#137844][#137844] | ||
|
|
||
| - Several metrics are redundant and have been removed. The following list maps each removed metric to an existing, identical metric. [#138786][#138786] | ||
| - Removed `sql.schema_changer.running`, which is redundant with `jobs.schema_change.currently_running`. | ||
| - Removed `sql.schema_changer.successes`, which is redundant with `jobs.schema_change.resume_completed`. | ||
| - Removed `sql.schema_changer.retry_errors`, which is redundant with `jobs.schema_change.resume_retry_error`. | ||
| - Removed `sql.schema_changer.permanent_errors`, which is redundant with `jobs.schema_change.resume_failed`. | ||
|
|
||
| - The default value of the `autocommit_before_ddl` session variable is now `true`. This will cause any schema change statement that is sent during a transaction to make the current transaction commit before executing the schema change in a separate transaction. | ||
|
|
||
| This change is being made because CockroachDB does not have full support for multiple schema changes in a transaction, as described [here]({% link v25.1/online-schema-changes.md %}#schema-changes-within-transactions). | ||
|
|
||
| Users who do not desire the autocommit behavior can preserve the old behavior by changing the default value of `autocommit_before_ddl` with a command such as: | ||
|
|
||
| ``` ALTER ROLE ALL SET autocommit_before_ddl = false; ``` | ||
