What happened
On August 14, 2026, a new version 3.1.12.297 of the configuration “1C: Library of Standard Subsystems” (BSP) was published on the 1C:ITS portal. This is another update of the technological platform-builder, on the basis of which standard and industry solutions of the “1C” line are built.
The Library of Standard Subsystems is not a standalone accounting program, but a set of ready-made universal mechanisms and subsystems (user and rights management, data exchange, print forms, email, object versioning, scheduled tasks, and much more). Developers use it as a single foundation to avoid reprogramming standard functionality in each configuration. The appearance of a new version on the portal means that the updated set of components has become available for use in the development and support of applied solutions.
Who it concerns
The update is primarily aimed at technical specialists, rather than ordinary users of accounting and management programs.
- Partners and franchisees of 1C, who develop and implement solutions on the platform. - In-house developers and 1C specialists in companies that have modified or custom configurations based on BSP. - Administrators of information bases, responsible for the support and updating of corporate solutions.
For end users of standard configurations, the BSP release usually has no direct impact: changes reach them later — already “within” the next updates of applied programs, where the vendor integrates the current version of the library.
What to do
If you support a solution built on BSP, it makes sense to follow the standard procedure for working with updates:
1. Check access to the 1C:ITS portal and the presence of a valid support contract — distributions and updates are distributed through the portal. 2. Study the version composition in the accompanying information to the release to understand the scope of changes and their impact on your configuration. 3. Assess the compatibility of the new version of the library with the current edition of your solution and the version of the “1C:Enterprise” platform. 4. First test the update on a copy of the information base, not on the working one, especially if the configuration is no longer fully supported and contains modifications. 5. Plan the transfer of modifications — when updating BSP in modified configurations, careful comparison and merging of changes is often required.
If your own technical competence is insufficient, it is reasonable to contact the servicing partner of 1C: working with the library of standard subsystems requires developer qualifications.
Deadlines
The version was published on August 14, 2026, and is available on the 1C:ITS portal. There are usually no strict mandatory deadlines for transitioning to the BSP release — the transition is carried out as part of the planned support of the solution. It is recommended not to postpone the analysis of the update for too long: timely updating of the library simplifies subsequent updates and reduces the risk of accumulating discrepancies between your configuration and the standard base.
Frequently Asked Questions
What is “1C: Library of Standard Subsystems”? — It is a set of universal subsystems and mechanisms from 1C that developers use as a ready-made foundation when creating and supporting applied solutions, so as not to program standard functionality from scratch.
Does an ordinary user of the accounting program need to install version 3.1.12.297 themselves? — Usually not. The current version of the library is delivered to users as part of standard updates of applied configurations; separate installation of BSP is the task of developers and support specialists.
Where to download the update? — Distributions and updates are distributed through the 1C:ITS portal with a valid information technology support contract.
Is it mandatory to switch to the new version immediately? — The transition is carried out as part of the planned support of the solution. It is recommended to study the version composition in advance, check compatibility, and test the update on a copy of the database.
Can the update affect modifications in my configuration? — Yes, when updating BSP in modified solutions, comparison and merging of changes is often required, so such work is better entrusted to a qualified 1C specialist.
