Spectrum Technology Platform patches deliver fixes and improvements between major releases and service packs. The availability of patches for Spectrum Technology Platform versions depends on their general availability support tiers. Always review the patch details provided here before installing any patch.
Spectrum Technology Platform supports the following patch types:
- Cumulative patches (C‑patches): Starting with Spectrum Technology Platform version 2024.1, patches are primarily delivered as cumulative patches. These patches include all fixes and improvements from previous patches. They do not require sequential installation. You can install a cumulative patch directly without installing earlier patches.
- S‑patches: These are non-cumulative patches and must be installed in the order they are released.

Validate SHA-256 checksums values
An SHA-256 checksum is a sequence of numbers and letters that you can use to check that the downloaded copy of a patch update file is identical to the original.
Small changes in a file produce very different looking checksums. A single character difference produces a very different looking checksum. You can use checksums to check files and other data for errors that occur during transmission or storage. For example, a file might not have properly downloaded due to network issues. You can also use a checksum to help verify that an attacker has not made changes to a file.
If you know the checksum of the original file, you can run a checksum or hashing utility on it. If the resulting checksum matches, you know the file you have is identical.
You can compute a hash value in a Command Prompt or Powershell window.
Use the Windows command prompt to calculate SHA-256 checksums
Follow steps in this procedure to use the CertUtil command to compute the hash value for a downloaded patch file.
- Open a Windows Command Prompt window. To do this, type cmd in the Windows Start menu command box or in the Explorer window address bar.
- At the command prompt, type certutil -hashfile filename sha256.
Tip: You can type certutil -hashfile sha256, with two spaces between -hashfile and sha256, leave the insertion point between the two spaces, and drag the downloaded ZIP file onto the Windows command window.The command line should appear similar to the following:
C:\Users\UserName\Downloads>certutil -hashfile cdq20241s01.zip sha256
- Press Enter. This results in output similar to the following:
C:\Users\UserName\Downloads>certutil -hashfile cdq20241s01.zip sha256 SHA256 hash of cdq20241s01.zip: eaa6712855e9990e99aae0cce1da1b8c6a21ba15b3aadd887bfe34525e6b2963 CertUtil: -hashfile command completed successfully.
- Compare the calculated hash value with the original hash value. You do not have to look too closely, as there will be a massive difference in the checksum even if there is only a tiny difference in the underlying file.
Use Windows Powershell to calculate SHA-256 checksums
Follow steps in this procedure to use the Powershell Get-FileHash command to compute the hash value for a downloaded patch file.
- Open Windows Powershell. To do this, type powershell in the Windows Start menu command box or in the Explorer window address bar.
- Type Get-FileHash followed by a space.
- Drag the downloaded ZIP file onto the Windows Powershell window after the Get-FileHash command. The command line should look similar to the following:
PS C:\Users\UserName> Get-fileHash C:\Users\UserName\Downloads\cdq2019s14_Windows.zip
- Press Enter. This results in output similar to the following:
PS C:\Users\UserName> Get-FileHash C:\Users\UserName\Downloads\cdq20191s14_Windows.zip Algorithm Hash Path --------- ---- ---- SHA256 BD94760347BABBB0B12ADFEB41FF01B90DD7F4C16F9B6C2088CD2526F6223898 C:\Users\UserName\Downloads\cd...
- Compare the calculated hash value with the original hash value. You do not have to look too closely, as there will be a massive difference in the checksum even if there is only a tiny difference in the underlying file.
