Due to the discovery of a potentially serious issue in the 11.1.1d release of Synergy/DE, we have decided to withdraw that release on Windows and UNIX platforms and replace it with 11.1.1e, which is now available.

To understand the issue, it is first necessary to understand that enabling compression on a data file can, in rare cases, result in a small increase in the size of some records! This can only occur if the data in a record is not compressible, yet the compression itself adds a small overhead.

It was found that when reading records from a compressed file, by RFA, any records exhibiting this “negative compression” would have one byte of bad data returned at the end of the record.

11.1.1e includes new versions of Synergy/DE 32-bit and 64-bit for Windows and Unix platforms, and Synergy DBL Integration for Visual Studio (build #2769).

We strongly recommend that anyone who has updated to Synergy/DE 11.1.1d on the affected platforms should immediately upgrade to 11.1.1e.

As we needed to release a new version to address the READ by RFA issue, we decided to also include several other quality improvements that had already been completed.

Synergy/DE Runtime

(Windows) In 11.1.1d, when using SYN_RESIZE_SCALE or having a monitor DPI change, some .NET controls would fail to repaint if the application moved between monitors of different DPI or scaling.

Traditional Synergy Compiler

A global structure with the same name as a subroutine no longer causes a segmentation fault when loading prototype files when there are different prototype files for the global structure and the subroutine.

Synergy Configuration Program

We addressed an issue in rsynd that was causing the SynConfig utility to fail with a “Could not complete services import” error when specifying a user account during service import.

Synergy DBMS

We enhanced the isutl utility when recovering change tracking files with bad change tracking links, and the utility no longer crashes if certain wildcard file operations are attempted.

Visual Studio Build System

We fixed an issue in the incremental build feature in SDI 11.1.1d-2749 through 11.1.1d-2763 that caused full project builds to occur when only partial builds were necessary for projects using common.props and with non-Synergy references.

We fixed an issue that prevented low-level libraries in Synergy .NET Core solutions from automatically rebuilding when an output file was missing.

Visual Studio Property Pages

We fixed an issue that prevented Visual Studio settings imported from a file from working until a Synergy DBL option page (Tools > Options > Text Editor > Synergy DBL > …) was opened.

We fixed an issue with Synergy .NET Core and .NET Standard projects that prevented SDI from resolving known MSBuild properties used for pre-build and post-build events.
