What happened
On 8 October 2026, a new version of the 1C:Standard Subsystems Library, 3.1.12.348, was published on the 1C:ITS Kazakhstan portal. This announcement is primarily important for developers, implementation consultants, and specialists who support solutions on the 1C platform and use the library when developing or updating configurations.
The 1C:Standard Subsystems Library is a set of ready-made mechanisms used in 1C application solutions. Therefore, the release of a new version may be significant not only for independently developed solutions but also for products in which the relevant subsystems are already embedded.
The original announcement does not provide a list of changes in version 3.1.12.348. Before installation, the publication on the 1C:ITS portal should be opened and the available release description, requirements, and supporting materials should be reviewed. The presence of specific fixes or new features should not be assumed without confirmation in the official documentation.
Who is affected by the update
Kazakhstan organisations that independently customise 1C configurations or engage a contractor for support should take note of the release. The information is primarily relevant to:
- developers and solution architects working on the 1C platform;
- implementation and support specialists;
- information database administrators;
- owners of industry-specific and custom configurations;
- companies planning to update an application solution.
The mere publication of the library does not mean that it must be installed immediately in all production databases. It is first important to determine whether it is used in a particular configuration, whether the release is compatible with the current version of the solution, and whether its implementation is provided for by the product developer or vendor.
Users of standard software without custom modifications generally do not need to replace the library themselves. As a rule, the necessary changes should be delivered as part of an update to the relevant configuration. It is advisable to agree on the procedure with the specialist responsible for supporting the database.
What to check before installation
The update should be performed according to a controlled procedure. Before starting work, the current versions of the platform, configuration, and embedded library should be identified, and the availability of official release documentation should also be checked.
A practical preparation procedure may be as follows:
- Identify which information databases and development projects use the Standard Subsystems Library.
- Review the official description of version 3.1.12.348 and its compatibility requirements.
- Document the existing customisations and assess whether they may overlap with the mechanisms being updated.
- Create a verified backup copy of the information database and related settings.
- First perform the update in a test environment without affecting the production database.
- Check solution startup, access rights, background jobs, data exchanges, printed forms, and key user operations.
- Transfer the changes to the production environment only after successful testing.
Non-standard configurations require particular attention. If standard library objects have been modified manually, automatic merging may cause conflicts. In this case, the developer must compare the changes and preserve the required business logic.
Time frames and next steps
The release publication date has been confirmed as 8 October 2026. The provided data do not specify a mandatory deadline for its installation. An organisation may include a review of the new version in its own support schedule, taking into account the criticality of the information database and the test results.
After the update, it is useful to retain information about the installed version, the date of the work, and the verification results. If the release is to be used in an in-house development project, the project's technical documentation should also be updated. If the organisation lacks the necessary experience, it is safer to entrust the analysis and installation to a qualified 1C specialist.
Frequently asked questions
What exactly was published on 8 October 2026? — Version 3.1.12.348 of the 1C:Standard Subsystems Library was published on the 1C:ITS Kazakhstan portal.
Does the production database need to be updated immediately? — Not necessarily. The applicability and compatibility of the release and the results of its installation in a test environment should be checked first.
Is the update intended only for Kazakhstan? — The announcement was posted on the 1C:ITS Kazakhstan portal. The scope of application of the version itself should be confirmed using the official release description.
Can the library be installed without a backup copy? — This approach creates unnecessary risk. Before modifying the production database, it is recommended to prepare and verify a backup copy.
Where can the list of changes be found? — It should be sought in the official publication and supporting documentation on the 1C:ITS portal; the provided data do not contain a detailed list of changes.
