This is the change log of the Real-Time SDK (RTSDK) for C++/C. RTSDK consists of Enterprise Message API (EMA) and Enterprise Transport API (ETA). This file contains history starting from version 1.2.0 which is when all components (EMA C++, EMA Java, ETA C, ETA Java) of RTSDK were fully open sourced. Note that RTSDK product version numbers start from 1.2.0 and EMA/ETA version numbers start from 3.2.0.

There are three types of RTSDK releases that append a letter directly followed by a number to the version number.

"L" releases (e.g., 2.2.0.L1) are full RTSDK releases that are uploaded to MyAccount, Developer Community and GitHub. "G" releases (e.g., 2.2.0.G1) are releases that are only uploaded to GitHub. "E" releases (E-Loads) are emergency RTSDK releases that are uploaded to MyAccount and Developer Community but not to GitHub. Also note that emergency releases may only be partial (i.e., Java or C++/C only).

CURRENT RELEASE HIGHLIGHTS - RTSDK C/CPP 2.2.3.L1 aka EMA/ETA 3.8.3.L1 aka 3.8.3.0

This release of EMA C++ has support for the Preferred Host feature which applies to both channelset and warm standby: the feature allows a switch back to a preferred host in channelSet configuration or a preferred group in warm standby configuration.

In addition, this release serves as a maintenance release with support for Windows 11, customer issue fixes and other minor enhancements. Note that starting with this version, EMA configuration is validated and enforced using an embedded schema file.

RTSDK C++/C Release 1.2.0.L1 (April 27, 2018)

New Features Added

RTSDK C/C++ now utilizes a CMake build environment. Refer to the RTSDK C/C++ Migration Guide for detailed instructions regarding how to build EMA C++ with CMake.

RTSDK C/C++ now supports Visual Studio 2017.

EMA now supports encrypted connection type.

ETA C is now fully open sourced except for reliable multicast transport and VA cache. Open source transports include TCP, HTTP, HTTP encrypted, shared memory and sequenced multicast transport types. The OMM encoder and decoder have also been open sourced.

Note that the memory footprint has increased this release due to the following:

Around 20 MB is introduced by changing the container type for handling message fragmentation. The hash table is initialized when a rsslChannelImpl is created which ETA allocates 10 of them upfront for this first initialization of Rssl library.

Around 4.6 MB is introduced by the new functionality of RsslDataDictionary to look up RsslDictionaryEntry by name (rsslDictionaryGetEntryByFieldName).
