| User type | Action required |

| Trial users upgrading from 1.x | Obtain a kdb-x community license from the KX Developer Portal. |
| Commercial users upgrading from 1.x | Use a kdb-x K4 license. Contact support@kdb.ai if you need assistance. |
| Existing kdb-x community license holders | No action required. If your license is installed at $HOME/.kx/kc.lic, it is ready to use. |

3. Structured error tags (New)¶
Errors now include a structured tag in the format KDBAI-[FILE_TAG]-[FUNC_TAG]-[NNN], for example:

Structured tags make issues faster to identify, search, and report to support.
