Additional information:

The NLCIUS G-Account extension's versioning has been realigned to
conform to the standard used in SI-UBL 2.0 and NLCIUS-CII, where the
first three numbers in the version correspond to the version of the
specification, and the fourth number corresponds to the version of
the schematron validation files. Therefore, version 1.0.9 will be
renumbered to 1.0.2.9. This is technically a version downgrade, but we
think potential confusion from that is less of an issue than the
current misalignment between the specification version and the
schematron version. From now on, the version of the G-Account
schematron validation files will have 4 numbers and follow the standard
versioning scheme.

The only other change for all three formats is the update of the
underlying CenPC434 rules.

Please note: This release is in effect as of February 26th, 2024.

This release only contains an update of the underlying validation rules for the European Norm, EN-16931, to version 1.3.11.

A list of the changes in the EN-16931 rules can be found here: https://github.com/ConnectingEurope/eInvoicing-EN16931/releases

With this release, the version numbers are as follows:

SI-UBL: 2.0.3.8
SI-UBL g-account: 1.0.8
NLCIUS-CII: 1.0.3.7

Please note: This release will go into effect on 7 August, 2023. Until that time, the release tagged 2023-03-14 ("Hotfix november release") remains the mandatory version.

This release contains an update of the underlying validation rules for the European Norm, EN-16931, to version 1.3.10.

A list of the changes in the EN-16931 rules can be found here: https://github.com/ConnectingEurope/eInvoicing-EN16931/releases

There have been no changes in the validation for NLCIUS/SI-UBL-specific rules since the previous release.

With this release, the version numbers are as follows:

SI-UBL: 2.0.3.7
SI-UBL g-account: 1.0.7
NLCIUS-CII: 1.0.3.6

This is a hotfix release that fixes an issue that was introduced in the November release

This updated release can be deployed immediately, but will be mandatory as of 2023-03-27.

• Updated SI-UBL 2.0 (NLCIUS) to 2.0.3.6
• Updated SI-UBL 2.0 (NLCIUS) g-account extension to 1.0.6
• Updated NLCIUS-CII to 1.0.3.5

The november release introduced a new method to validate non-emptiness of a
number of fields, no longer accepting fields that contained only
white-space. However, a bug in this new check resulted in a number of
mandatory elements that were now no longer checked for existence (in
schematron). This made it possible to create documents that passed
validation though they were non-compliant to EN-16931. This update resolves
that issue.

Please note: This release is in effect as of February 6th, 2023.

This release contains an update of the underlying validation rules for the European Norm, EN-16931, to version 1.3.9. The most relevant change in that version is that the code for the Netherlands Chamber of Commerce Establishment Number was added to the ICD code list, with code 0217. Note that it was not added to the EAS code list, and cannot be used in for EndpointID values, only in PartyIdentification.

A list of the other changes in the EN-16931 rules can be found here: https://github.com/ConnectingEurope/eInvoicing-EN16931/releases

The validation for SI-UBL 2.0 and NLCIUS-CII also contains a bug fix: a CreditNote document without a PaymentMeans is no longer rejected.

With this release, the version numbers are as follows:

• SI-UBL: 2.0.3.5
• SI-UBL g-account: 1.0.5
• NLCIUS-CII: 1.0.3.4

Minor update: the tag for this release was 2023-02-06, due to an update to an internal version number in the title of SI-UBL 1.2 (it was version 1.2.4 but it claimed to be 1.2.3). There have no content or rule changes from the pre-release as published in november 2022.

This is the Spring 2022 release of the validation files. It includes updates for the following formats:

SI-UBL 2.0 g-account extension X.Y.Z:

• Made the CustomizationID a bit more lenient, so that other documents that are compliant to both NLCIUS and the g-account extension can use this validation as well. They MUST have a customizationID that starts with 'urn:cen.eu:en16931:2017#compliant#urn:fdc:nen.nl:nlcius:v1.0' AND contains '#conformant#urn:fdc:nen.nl:gaccount:v1.0'
