+# dbt_jira v0.19.0
+[PR #133](https://github.com/fivetran/dbt_jira/pull/133) contains the following updates:
+
+## Breaking Changes
+- This change is marked as breaking due to its impact on Redshift configurations.
+- For Redshift users, comment data aggregated under the `conversations` field in the `jira__issue_enhanced` table is now disabled by default to prevent consistent errors related to Redshift's varchar length limits. 
+  - If you wish to re-enable `conversations` on Redshift, set the `jira_include_conversations` variable to `true` in your `dbt_project.yml`.
+
+## Under the Hood
+- Updated the `comment` seed data to ensure conversations are correctly disabled for Redshift by default.
+- Renamed the `jira_is_databricks_sql_warehouse` macro to `jira_is_incremental_compatible`, which was updated to return `true` if the Databricks runtime is an all-purpose cluster (previously it checked only for a SQL warehouse runtime) or if the target is any other non-Databricks-supported destination.
+  - This update addresses Databricks runtimes (e.g., endpoints and external runtimes) that do not support the `insert_overwrite` incremental strategy used in the `jira__daily_issue_field_history` and `int_jira__pivot_daily_field_history` models.
+- For Databricks users, the `jira__daily_issue_field_history` and `int_jira__pivot_daily_field_history` models will now apply the incremental strategy only if running on an all-purpose cluster. All other Databricks runtimes will not utilize an incremental strategy.
+- Added consistency tests for the `jira__project_enhanced` and `jira__user_enhanced` models.

 Your Jira connector may not sync every table that this package expects. If you do not have the `SPRINT`, `COMPONENT`, or `VERSION` tables synced, add the respective variables to your root `dbt_project.yml` file. Additionally, if you want to remove comment aggregations from your `jira__issue_enhanced` model,  add the `jira_include_comments` variable to your root `dbt_project.yml`:
 ```yml
 vars:
-    jira_using_sprints: false   # Disable if you do not have the sprint table or do not want sprint-related metrics reported
-    jira_using_components: false # Disable if you do not have the component table or do not want component-related metrics reported
-    jira_using_versions: false # Disable if you do not have the versions table or do not want versions-related metrics reported
-    jira_using_priorities: false # disable if you are not using priorities in Jira
-    jira_include_comments: false # This package aggregates issue comments so that you have a single view of all your comments in the jira__issue_enhanced table. This can cause limit errors if you have a large dataset. Disable to remove this functionality.
+    jira_using_sprints: false    # Enabled by default. Disable if you do not have the sprint table or do not want sprint-related metrics reported.
+    jira_using_components: false # Enabled by default. Disable if you do not have the component table or do not want component-related metrics reported.
+    jira_using_versions: false   # Enabled by default. Disable if you do not have the versions table or do not want versions-related metrics reported.
+    jira_using_priorities: false # Enabled by default. Disable if you are not using priorities in Jira.
+    jira_include_comments: false # Enabled by default. Disabling will remove the aggregation of comments via the `count_comments` and `conversations` columns in the `jira__issue_enhanced` table.
 ```
+
 ### (Optional) Step 5: Additional configurations
 
+#### Controlling conversation aggregations in `jira__issue_enhanced`
+
+The `dbt_jira` package offers variables to enable or disable conversation aggregations in the `jira__issue_enhanced` table. These settings allow you to manage the amount of data processed and avoid potential performance or limit issues with large datasets.
+
+- `jira_include_conversations`: Controls only the `conversation` columns in the `jira__issue_enhanced` table. 
+  - Default: Disabled for Redshift; enabled for other supported warehouses.
+  - Setting this to `false` removes the `conversation` columns but retains the `count_comments` field if `jira_include_comments` is still enabled. This is useful if you want a comment count without the full conversation details.
+
+In your `dbt_project.yml` file:
+
+```yml
+vars:
+  jira_include_conversations: false/true # Disabled by default for Redshift; enabled for other supported warehouses.
+```
+
 #### Define daily issue field history columns
 The `jira__daily_issue_field_history` model generates historical data for the columns specified by the `issue_field_history_columns` variable. By default, the only columns tracked are `status`, `status_id`, and `sprint`, but all fields found in the Jira `FIELD` table's `field_name` column can be included in this model. The most recent value of any tracked column is also captured in `jira__issue_enhanced`.
