Metadata use is optimized for the work are loaded for the 1C:Enterprise 8 client, COM-connections, connections via Web-services.

Metadata caching at the client computer has been implemented.

Session parameters are now cached at the client computer which increases system performance when it works with configurations that have multiple calls to session parameters.

The conversion of non-periodical registers has been optimized.

A new operating mode of the accumulation and accounting register has been implemented – with a Totals splitter – which allows a greater concurrence of writing to the registers.
The possibility of deactivating of using current totals of accumulation and accounting registers.
The possibility of recalculating current totals for accumulation and accounting registers for the stated period.
The performance of writing to the accumulation and accounting registers with a large number of changes (extra dimensions) has been increased due to changes in the database tables index structure.
The writing to accounting and accumulation registers for past periods has been optimized.
The record set writing of the accounting and accumulation registers has been optimized.
The possibility of probable deadlocks when working with the calculation registers, which support Action period, has been significantly reduced.

For the values tables line search is optimized due to possibility of indexing.
The performance of the GroupBy() method has been optimized in the values table. The search in compliance with has been optimized.

The help search has been optimized by using a full-text search (with a search time of no more than one second).

The event log reading has been optimized. The system delay has been removed.

The database configuration update process has been optimized due to a reduced time of changes analysis.

All common work of the client application is performed in a single thread that the operating system creates at the application start. It effects that speed  when using COM-objects (created either by 1C:Enterprise or externally) is increased.

Document search by number in table boxes has been optimized.

Writing accumulation register record sets has been optimized for a scenario, when all or some records match the existing records of the database for the recorder.

Writing register records to accumulation and accounting registers has been optimized due to updating register totals in the privileged mode at the server.

The 1C:Enterprise script works faster.

Rows in large documents are obtained faster.

Restructuring for some configuration changes (e. g. adding and deleting attributes) is performed faster.

Transition from Version 8.0 to Version 8.1


The transition to 8.1.5 is possible only from version 8.0.10 and higher. It is recommended to update from version 8.0.17 and higher. In these versions there is a possibility to test and repair non-unique records in testing and repairing mode.

1C:Enterprise version 8.1 can be installed without uninstalling 1C:Enterprise version 8.0.

Attention!
The storage formats for infobases (file-based and client-server variants), configurations  and external data processors have been changed. In order to use them a conversion needs to be performed. Before the conversion you are recommended to back up the infobase (the configuration, the external data processor). After the conversion is complete, they cannot be used in 1C:Enterprise version 8.0. The restoration infobase file format obtained by 1C:Enterprise 8.0 is not compatible with 1C:Enterprise 8.1 platform, the restoration files using is possible only using  conversion of infobases, restored from this file.

Conversion can only be performed by an infobase user with administrative rights.

Attention!
Before the conversion you are recommended to make sure that metadata objects with numeric codes have code length not exceeding the 38 characters limit. If there are objects with long numeric codes in the configuration, then their codes should be reduced and data base should be restructurized. Otherwise, an error occurs when converting such a configuration, and this configuration can't be used neither in version 8.0, nor in version 8.1.

To convert from version 8.0 format, perform the following actions.

Infobase That Is Not Connected to a Configuration Repository

File-Based Infobase

Client-Server Variant of Infobase

Infobase Connected to a Configuration Repository

Configuration Dumped to a File

Infobase Dump File

External Data Processor

You can perform batch conversion for 1C:Enterprise version 8.x files, if you use the ConvertFiles command line option.

Using Configurations Designed in Previous Version of 1C:Enterprise

Application solution (configuration) users may need to perform a configuration version update when they move to the new 1C:Enterprise 8.1 platform version. We recommend that you obtain information regarding the configuration version update from the vendor (developer) of the solution.
When converting infobases of 1C developed business applications (including business applications demonstration bases) there are following features.                                                                       

Using the support files

The configuration distribution files (cf) require the same actions as those described in the Configuration Dumped to a File section. Update files (cfu) prepared by the 1C:Enterprise 8.0 version cannot be used for updating configurations converted for 1C:Enterprise version 8.1.

Attention!

After 1C:Enterprise 8.0 configuration is converted there may be incorrect work of modules, included into configuration without sources or password protected, that use renamed in 1C:Enterprise 8.1 objects and script methods (see the Changes that Require Configuration Changes or Influence System Behavior section for the list of such objects and methods).
For the password protected modules you should enter the editing mode, make necessary changes (according to renaming) and save module.
For the modules without sources you should update form new version of configuration, prepared in 1C:Enterprise 8.1.

Attention!

Because of errors in version 8.0.7 and earlier, as a result of work in version 8.0 the error records with not unique field values can appear in the sequence table and sequence border table. When working in 8.0 version such records didn't cause system logic violation (it could just decrease system performance slightly). The error appears when trying to restore such an infobase data into client-server variant of 1C;Enterprise 8.1 (not depending on selected Database type).
To recover problems with sequence border tables you should execute infobase testing and repairing. It can be performed both in 8.0 version (since 8.0.17) and 8.1 version after infobase conversion.
To recover problems with sequence tables you should perform infobase conversion in the following way:

Changes that Require Configuration Changes or Influence System Behavior

The metadata objects' maximum numeric code length has been changed. Now it's equal 38 characters.

DocumentObject.<name> object's  RegisterRecords property changed type from FixedCollection to RegisterRecordsCollection.

When an accounting register record set is written without replacement of the existing set in the OnWrite() predefined procedure, the record set content does not differ from that formed while writing the set.

When executing Save as copy menu command for a spreadsheet document, in the list of possible file types an Excel Sheet type now means saving a spreadsheet document in the Excel 97 format rather than in Excel 95 as before. In addition the Excel sheet 95 and Excel sheet 97 types have been added to the list of possible types explicitly specifying the Excel sheet type.

The mail message id generation had been changed in case this property is empty in the received message. The id is generated by RFC rules.
The behavior has been changed for the retrieval of empty Name and FileName fields in a mail attachment. Now if at least one is filled, the second is filled from the first one, and if both are empty the attachments names are regenerated automatically.

An auto convert of a line feed is not performed during text reading and writing. The line feed characters, which were in source text, remain in script.

A header (text and icon) is displayed for the modal form in the desktop mode.

Without a right for interactive editing (and the Interactive Posted Change right for documents) a form does not allow a record to be executed using a form standard command and the WriteInForm() 1C:Enterprise script method even if a change of the edited object is performed using the 1C:Enterprise script and not interactively.

The algorithm of empty values in input field and register dimensions check has been changed. The value of Boolean type is always treated not empty. The value of String type is checked by rules according to IsBlankString() function.

When a new infobase is created, a mode for registering the events of all severity levels is set for the event log.

The event log is not cleared when an infobase is restored from the file.

If command line contains several parameters, describing path to the infobase (File and Srvr), then last mentioned is used.

When installing 1C:Enterprise 8.1 on computers under Microsoft Windows XP or Microsoft Windows Server 2003 Operation systems, it is recommended to use GDI+ library's version, which is included in operation system. When installing 1C:Enterprise system on computers under other operation systems, it's recommended to use GDI+ library version which is included in 1C:Enterprise 8.1 distribution kit.

The objects locking mechanism (Lock() method) has been changed. The database object lock does not prevent the object from being modified or deleted. Object form extensions perform lock automatically in order to provide the object protection from concurrent editing by different users.

The line comparison algorithm has been changed due to transition to using open-source IBM ICU library.

The 1C;Enterprise 8.1 command line parameter identificators have been changed: SQLSrvr became DBSrvr, SQUID became DBUID, SQLPwd became DBOwd. The compatibility with old identificator variants has been preserved.

Since the autonumber procedure has changed, each number assigned will be sequential, even if the previous object is not written. You are not recommended to use numerals in number and codes prefixes in order to autonumber procedure work correctly.

When you insert data in a document form, the Enabled property of a control linked to the Posted field is False by default. After you update to v 8.1.5 the previously existing controls of this type have their Enabled property set to True.

If you read object data from the database (obtain the object and call the reference) in a transaction in the controlled mode, the object transaction lock is not used. If you need the lock, you should use the 1C:Enterprise script to set it before calling the object.

If a query contains the ALLOWED keyword and you call a field over the period from a field that has complex type and contains a reference, it will not return an error of insufficient rights to a specific table. The returned value for the field will be NULL. For tables which a user have rights to the behavior will stay the same.

The procedure for changing the checkbox state in multiple selected rows of the table box has changed. Now the checkbox can be changed for the current row only, while its state in other rows does not change.

The Both search direction in the table box is renamed as From The Beginning. The default search direction has been changed. By default the search direction is From The Beginning; if the search start at the last row of the table box, it is Backward.

The procedure for displaying standard pictures in the table box has changed. If the DisplayDefaultPicture property is set for the table box column, the RowsPictures property is not used.

For lists of documents, document journals, accounting registers, accumulations registers, data (periodic), business processes and jobs the standard behavior of going to the list start or end has changed.

You can control filtering by recorder when you open a register list from the document form or the document list form by clicking Go To.
When you change the list filter for all registers subordinate to the recorder, it can set the order that is optimal for the filter.

The algorithm for generating infobase connection numbers has changed. The number of each subsequent connection to the infobase exceeds the previous connection number by one (instead of assigning a minimum unused number). In the client-server variant a new connection is assigned number 1 only after the rmngr process is restarted. Number 0 is only assigned to service connections that are not linked to any infobase. In file-based infobases a new connection is assigned number 1 only after all clients, including scheduled and asynchronous jobs, are disconnected from the infobase.

When a form item is added by using the Add() method, the FormItems collection checks whether the item name matches the variable naming rules of 1C:Enterprise script.

In the general case the Map object elements bypass order isn't not corresponding with order of inserting them in into it. In version 8.0 the bypass order could correspond with the order of inserting them (in case that corresponding keys' values were values of nonprimitive types).

 The exception call has been implemented for working with XMLWriter object. The exception is called when writing methods are called before one of XML data sink setting method: SetString() or OpenFile().

The directory for the following setting files has been changed:

Autosearch and attachment of template files has changed. The procedure attaches only templates with file names that contain postfixes corresponding to the selected programming language or that contain no language postfixes.

The default user name for 1C:Enterprise server has been changed from user1cv81server to usr1cv81.

The COM-objects names of 1С:Enterprise 8.1 have been changed:

The Depot command line parameter has been changed to ConfigurationRepository.
The following terms has been changed:

The DESIGNER command line parameter has been renamed. The previous CONFIG parameter is still supported for compatibility.

The ApplicationPresentation() global context method, that returns the localized presentation of the application name, now has an instruction represented by a parameter (Designer line) that identifies the Designer. The previous parameter value (Config) is supported for compatibility.
When the event log is unloaded to XML, the Designer application is represented by the Designer term in the Application column.
The event log legend file uses the Designer term to represent the Designer application. To ensure compatibility with legend files of the old event log, the previous value of the Config term is supported.
