Sling v1.5.15 (2026-04-15T22:44:09Z)

New Features

• CDC support for PostgreSQL, SQL Server, Oracle, and MongoDB: Change Data Capture now works with PostgreSQL (logical replication), SQL Server, Oracle, and MongoDB sources — previously only MySQL was supported.
• CDC initial snapshot cursor-based resume: Initial CDC snapshots now use keyset-based chunking for string/UUID primary keys, enabling reliable cursor-based resume after interruption.
• CDC catch-up mode with end position: CDC ReadChanges now captures the current position before streaming so catch-up runs terminate without waiting for new events.
• Default adjust_column_type for CDC: CDC replications now default adjust_column_type to true, automatically widening target columns (varchar length, decimal precision) when the source schema changes.
• adjust_column_type precision expansion: The adjust_column_type option now detects and expands varchar length and decimal precision/scale when the source columns grow wider, avoiding truncation or precision loss.
• description parameter for SQL query actions: MCP database.query and worksheet logging now accept an optional description field for improved context and observability.
• MCP worksheet query logging: MCP SQL queries are now appended to a worksheet log file with metadata (connection, description, timestamp, duration, columns, row count), with automatic size trimming.

Bug Fixes

• Oracle SID/service_name conflict: Fixed Oracle connection strings where the SID option could conflict with service_name, causing connection failures.
• Progress update crash when replication is nil: Fixed a panic when updating task progress on a task with no associated replication.
• API spec record limit not stopping iteration: Fixed an issue where the API spec record limit was not properly stopping inner iteration loops during rule evaluation.
