 #### New Features
-* Added ability to set [SQL Security](https://clickhouse.com/docs/en/sql-reference/statements/create/view#sql_security) for normal views, referenced by [issue 359](https://github.com/ClickHouse/dbt-clickhouse/issues/359).
-* Add support for "microbatch" incremental strategy.
-* Added support for [TTL (time-to-live)](https://clickhouse.com/docs/guides/developer/ttl) as a column configuration for `table` and `ephemeral` materializations. This feature is implemented as a [custom constraint](https://docs.getdbt.com/reference/resource-properties/constraints#custom-constraints), which requires model contracts to be enforced. For example:

 ### Improvements
-* Upgrade `dbt-core` to version `1.9` and `dbt-adapters` to `>=1.10` ([#403](https://github.com/ClickHouse/dbt-clickhouse/pull/403))
-* Previously, delete_insert would fall back to legacy silently. Now it raises an error if LWD is not enabled.
-* Refactored the logic for applying the `ON CLUSTER` clause during model creation.
+* Upgrade `dbt-core` to version `1.9` and `dbt-adapters` to `>=1.10` ([#403](https://github.com/ClickHouse/dbt-clickhouse/pull/403)).
+* Escape column names in comments ([#428](https://github.com/ClickHouse/dbt-clickhouse/pull/428)).
+* TTl is now available for distributed tables ([#430](https://github.com/ClickHouse/dbt-clickhouse/pull/430)).
+* Previously, delete_insert would fall back to legacy silently. Now it raises an error if LWD is not enabled ([#447](https://github.com/ClickHouse/dbt-clickhouse/pull/447)).
+* Refactored the logic for applying the `ON CLUSTER` clause during model creation ([#447](https://github.com/ClickHouse/dbt-clickhouse/pull/447)).
     - Previously, `ON CLUSTER` was inconsistently applied based on engine type and materialization, often leading to confusion and unexpected results.
     - Now, if a `cluster` is defined in the profile and the engine is **not** `Replicated`, the `ON CLUSTER` clause will **always** be added by default.
     - A new model-level config `disable_on_cluster: true` has been introduced to explicitly opt out of this behavior.
