Interfacing with the Julia language has been added. Julia is dynamically typed scripting language that deploys garbage collection. It can be considered as an alternative to Python. The bindings are dynamic, there is no overhead when Julia is not used. Supported are:

• Loading and interpreting Julia source code
• Calling to Julia functions from Ada
• Calling Ada from Julia (no building a relocatable library required)
• Conversion from scalar Ada types to Julia types and back
• Arrays 1D, 2D, 3D (Julia has proper arrays like Ada does)
• Named and anonymous tuples
• Catching and raising Julia exceptions
• Julia's garbage collection control

The latest version provides support for OpenSSL. Now all protocols can be used with a securty layer based on TLS provided by OpenSSL rather than only GNUTLS. The motivations behind is that OpenSSL is supported by a wider range of platforms. E.g. if you need VxWorks then OpenSSL would be a natural choice. The latest OpenSSL 1.1.1 is supported.

Here is the list of changes:

• The package OpenSSL was added to provide bindings to OpenSSL;
• The package GNAT.Sockets.Server.OpenSSL was added to support secure servers based on OpenSSL;
• Multiple procedures were added to the package GNAT.Sockets.Connection_State_Machine.ELV_MAX_Cube_Client to support devices topology management and time management;
• Race condition in Object.Release fixed. The profile of the primitive operation Object.Decrement_Count has been modified.

The new version comes with ASN.1 support. Using ASN.1 requires no code generator. The way of ASN.1 encoding and decoding is deduced from the structure of record type containing type representing ASN.1 components.

The list of changes:

• The package OpenSSL was extended;
• Added implementation of ASN.1 encoding. The packages GNAT.Sockets.Connection_State_Machine.ASN1.* provide ASN.1 object encoding;
• X.509 ASN.1 certificates implementation added;
• LDAP implementation added.

[dmitry-kazakov]

The new version provides an implementation of JSON (RFC 7158). The implementation supports both parsing and output of JSON objects. The parser allocates parts of the JSON object in a user-provided storage pool that can be an arena stack allowing both performance and safety by limiting the overall size of the object.

[dmitry-kazakov]

The new version incorporates the following changes:

• SQLite3 bindings support tracing. The change is backward compatible with the older versions of SQLite3 that do not support tracing. In that case turning tracing on is a void operation;
• JSON parser implementation does not use program stack when dealing with large arrays.

[dmitry-kazakov]

The new version 4.44 fixes the following issues:

• Finalization of HTTP_Session extended to include cleanup, so that the object can be reused after calling to Finalize.
