5.19 Release notes

Upgrade guides​

5.19.3 Patch notes​

Release date

Cinchy version v5.19.3 was released on July 8, 2026.

Bug fixes​

  • Fixed an issue in the query editor where certain queries reported an incorrect result count, so the pager never appeared even when the query returned many rows. Affected queries now report the true row count and paginate correctly.
  • Fixed the query editor rendering an empty result grid after paging. If you paged past the first page of one query's results and then ran a different query returning fewer rows, the new query could display no rows. The result grid now always starts at the first page when a query is executed.
  • Fixed the Compress JSON setting being silently turned off when re-saving a saved query. Re-saving a query now preserves the setting.

5.19.2 Patch notes​

Release date

Cinchy version v5.19.2 was released on July 6, 2026.

Bug fixes​

  • Fixed pagination in the query editor's saved-query result grid, where paging was stuck on the first page. Requesting any page re-showed the first page of results, so you could not page through the full result set (and had to export to CSV to see all rows). Paging now advances correctly through every page.
  • Fixed the Recycle Bin Restore action reporting "Restore failed" even when the rows were successfully restored. Restore now reports success correctly; a genuine failure still surfaces an error.
  • Shipped the collaboration-log pagination off-by-one fix noted in v5.19.1. That fix was corrected in source for v5.19.1 but was not included in the deployed build, so the incorrect count (for example, "1 to 6 of 6" for a record with 7 versions) persisted at runtime. The rebuilt collaboration-log bundle in v5.19.2 includes the fix, so the count now displays correctly.

5.19.1 Patch notes​

Release date

Cinchy version v5.19.1 was released on June 30, 2026.

Bug fixes​

  • Fixed an issue where accented or non-ASCII characters in CSV, TSV, and PSV responses from the Cinchy API could appear as garbled text (for example, Équipe rendering as Équipe) in some clients, such as web browsers and Python REST clients. The API now declares the UTF-8 charset on these responses so all clients decode them correctly. JSON and XML responses were not affected.
  • Fixed an off-by-one issue in the collaboration log where the pagination total could display an incorrect record count on the first page for records with 25 or fewer versions (for example, showing "1 to 6 of 6" for a record with 7 versions). All version rows remained accessible; only the displayed count was affected.

5.19 Release notes​

Release date

Cinchy v5.19 was released on April 2, 2026.

New capabilities​

Cinchy MCP Server​

Cinchy v5.19 introduces the Cinchy MCP Server, a Model Context Protocol (MCP) server that lets AI assistants like Claude interact directly with your Cinchy data platform.

MCP is an open standard created by Anthropic that provides a universal interface for AI models to interact with external tools and data sources. Think of it as USB-C for AI: one protocol that connects any AI client to any data platform.

With the Cinchy MCP Server, you can use natural language in your AI assistant to query tables, insert and update data, troubleshoot data syncs, and more. All operations are authenticated under your own identity and respect Cinchy's row and column-level entitlements.

v5.19 ships with 21 tools across five categories — Core, Data, Syncs, Discovery, and Platform — covering everything from listing tables and running CQL to triggering syncs and diagnosing failures. Authentication uses OAuth 2.1 with PKCE; every tool call runs as the authenticated user, so Cinchy's row- and column-level entitlements are fully enforced.

For the full architecture diagram, complete tool catalog, security model, and Claude Desktop setup steps — including tools added in later releases — see the Cinchy MCP Server guide.

Bug fixes​

  • Fixed an issue where the Cinchy Connections WebApi IIS package did not include the correct IBM DB2 native driver libraries for Windows. The build pipeline now produces platform-specific builds for both Linux and Windows (IIS), ensuring that DB2 data sources work correctly on IIS deployments.
Post-upgrade step for IIS customers using DB2

After upgrading Cinchy Connections to v5.19.0 on IIS, you must add the DB2 CLI driver to the system PATH and restart IIS. Run the following in an elevated PowerShell prompt on the machine hosting Cinchy Connections:

$clidriver = "<path\to\clidriver>"
[Environment]::SetEnvironmentVariable("PATH", "$clidriver\bin;$clidriver\bin\icc64;$env:PATH", "Machine")
iisreset

For example, if Cinchy Connections is installed at C:\inetpub\wwwroot\Connections:

$clidriver = "C:\inetpub\wwwroot\Connections\clidriver"
[Environment]::SetEnvironmentVariable("PATH", "$clidriver\bin;$clidriver\bin\icc64;$env:PATH", "Machine")
iisreset
warning

If the Cinchy Connections Worker is hosted on a separate machine, repeat this process on that machine as well.
