1C:Enterprise 8.3.27: What Changed in the New Platform Release and Why Your Business in Uzbekistan Should Care

In the summer of 2026, 1C released a new version of its "1C:Enterprise" technology platform — 8.3.27. At first glance, it looks like just another routine update, the kind that ships several times a year. But behind the list of technical fixes are changes businesses will actually notice: operations that used to take minutes now run several times faster, and for the first time in a while, upgrading to the new version is promised to be nearly painless. For companies in Uzbekistan running 1C:Trade Management, 1C:Small Business Management, or 1C:ERP, that's a good reason to figure out whether it's worth updating now or safe to wait.

The main changes in release 8.3.27

Every new platform version usually balances three goals: making the system faster, safer, and more convenient for developers. In 8.3.27 the emphasis is clearly on performance and stability — the kind of change a user might not notice directly, but will definitely feel in how the database responds.

Searching for all references got several times faster

One of the most noticeable changes is a rework of the mechanism for finding all references to an object. This operation is familiar to anyone who has ever tried to figure out whether it's safe to delete a customer, an item, or a document: the system has to scan the entire database and find every place the object is used. In large databases — with several years of history and tens of thousands of documents — this could take a noticeable amount of time. According to specialized 1C sources, in the new platform version reference search runs several times faster. For companies with large databases that regularly clean up catalogs and archive data, that's a direct time savings for accountants and database administrators.

TCP data transport was reworked

The second significant fix is a rework of how data is transmitted over TCP connections. This is a low-level but important part of the platform: it determines how stable the client-server link is, especially under remote work, weak connections, or heavy server load. For companies whose employees connect to the database from different offices or branches — a common setup for trading and manufacturing companies in Uzbekistan with multiple locations — more reliable data transport reduces the risk of dropped sessions and a frozen interface.

Technology log cleanup was optimized

The technology log is a built-in diagnostic tool that accumulates service logs about system operation: errors, slow queries, locks. Over time these logs grow and, if not cleaned up, start affecting server performance themselves. In 8.3.27, the process of removing outdated log entries has been optimized, reducing the load on the server's disk subsystem — especially noticeable on servers that host several databases at once.

Email-based authentication

Among the user-facing rather than purely infrastructural changes, it's worth noting the addition of email-based authentication. Previously, logging in was usually built around a login-password pair, the operating system, or OpenID providers. Now an administrator can configure sign-in by email — a simpler setup for cases where an employee already has a corporate mailbox but no separate domain account, and setting up a full integration with an external identity provider would be overkill for a small company. For small and mid-sized businesses that often operate without a dedicated IT department, this is a convenient middle ground between a plain password and a full corporate SSO system.

The update also reached 1C's service ecosystem

The platform release isn't the only thing that changed in the 1C ecosystem this summer. Alongside 8.3.27, the "1C-Connect" service was also updated — a remote-access and online consultation tool that partners and support teams use when configuring and maintaining databases. For businesses, this means that specialists servicing 1C remotely now have an updated toolset for diagnostics and troubleshooting without an on-site visit — particularly useful when a company's office is in one city while its warehouse or production site is in another. Together, these changes point to a broader pattern: 1C is improving both the platform core and the tools its partners and integrators rely on to support clients.

Upgrading without conversion — why it matters more than it sounds

One formal but practically important detail deserves its own mention: moving from the previous platform version to 8.3.27 does not require converting configurations, databases, external data processors, or external reports. That sounds like a technical footnote, but compatibility is usually exactly what stops companies from updating the platform in the first place. Any 1C update carries risk: you need to test customizations, confirm that external reports and processors still open, and make sure integrations with your website, Bitrix24, or bank client software haven't broken. When conversion isn't required, both the risk and the effort of updating drop sharply — which widens the window in which a company can safely move to the new version without interrupting day-to-day accounting or warehouse operations.

What this means for business in Uzbekistan

In practice, for most companies using 1C in Uzbekistan, release 8.3.27 isn't a reason to update tomorrow morning, but it is a good reason to plan the move over the coming months. A few practical points:

• Large databases should update first. If a database has been running for several years, contains tens of thousands of documents, and regularly needs catalog cleanup, the faster reference search will produce a noticeable effect within the first weeks after updating.
• Companies with remote or distributed teams should pay attention to the data transport changes. A more stable TCP connection matters most when employees connect from branches, from production sites, or from home over VPN.
• Testing is still required before updating. Not needing mandatory conversion lowers the risk, but doesn't remove the need to check a customized configuration, reports, and integrations on a test copy of the database — especially if the configuration has significant changes relative to the standard solution.
• Updating the platform is not the same as updating the configuration. The platform and the application solution (Trade Management, Small Business Management, ERP, Accounting) are updated separately, so moving to a new platform version should be coordinated with the release cycle of the configuration in use to avoid temporary incompatibility.

For companies that have already been thinking about automating their accounting given current electronic reporting requirements, the updated platform provides extra performance and stability headroom — a technical foundation that makes it easier to roll out new modules and integrations without running into the limits of an outdated version.

Summary

The 1C:Enterprise 8.3.27 platform release is a good example of how a "technical" update ends up affecting the business directly: faster reference search saves time when working with catalogs, reworked TCP transport makes remote work more stable, technology log optimization reduces server load, and email authentication simplifies access management without extra infrastructure. The main practical advantage is upgrading without mandatory conversion of databases and processors, which lowers both the risk and the effort involved. Companies with large databases and distributed teams should plan the move over the coming months, testing their customized configuration on a database copy beforehand.
