sgcWebRTC is a new WebRTC media engine for Delphi and C++ Builder: SDP signalling, ICE with STUN and TURN, DTLS-SRTP, SCTP data channels and Opus, G.711, VP8 and H.264 media, with no browser and no WebView…

sgcOpenAPI 2026.9.0 rewrites the parser: OpenAPI 3.1 and 3.2, a Warnings list instead of silent failures, working schema composition, correct enums, safe external references and a scriptable command line…

sgcSign 2026.9.0: trust anchors in verification, richer certificate lists, multi-slot PKCS#11 without a PIN, two new PAdES profiles, signed timestamp requests and one shared HTTP transport…

sgcHTML adds CameraScanner, NumPad, CommandPalette and EmptyState, then puts all four to work in five brand new live demos: a Warehouse, a Point of Sale till, Reports & Analytics, a Multi-Tenant SaaS platform and Field Service…

A Huobi and HTX signing defect mixed the local date with the UTC time, so a host running outside UTC had every private request fail for part of the day. It read as an intermittent authentication problem, and it was a two-line fix…

Four Kraken defects fixed in 2026.9: the spot WebSocket client was speaking v1 while connected to a v2 endpoint, Futures REST orders went out as GET with the signed body discarded, and private subscriptions never replayed after a reconnect…

sgcWebSockets 2026.9.0 adds the sgcHTML Design Surface, so pages can be composed visually on a VCL form instead of only in code, using the exact same components and producing the exact same HTML…

Your AI assistant has never read the eSeGeCe source, so it invents properties that do not exist. Agent skills fix that, free and MIT licensed…

sgcCrypto is a new 43-unit cryptography library for Delphi and C++ Builder: AES-GCM, ChaCha20-Poly1305, SHA-3, Argon2, Ed25519, X.509 and post-quantum ML-KEM, ML-DSA and SLH-DSA, included free from sgcWebSockets Standard up…

sgcWebSockets 2026.8 adds QUIC and HTTP/3 components, OpenSSL linked inside the executable, more than 30 new sgcHTML components, a rewritten SChannel TLS layer, zlib 1.3.1 and a CycloneDX SBOM…

The installer now produces a CycloneDX SBOM for the edition being packaged and installs it as sbom.cdx.json, so the file can never drift from the code it describes…

zlib moves from 1.2.12 to 1.3.1. Because zlib is linked statically, the update meant rebuilding three separate object sets and proving them on every supported compiler…

Read Retry-After on an HTTP 429, subscribe a whole watchlist with one frame, and stop exchanges closing your connection after a reconnect…

sgcProtoBuf turns Protocol Buffers definitions into Delphi units, resolving imports recursively and generating one unit per package…

Attach the OpenAPI plugin to TsgcHTTPRESTServer and let one spec drive routing, validation, security and Swagger UI, with a single assignment as the whole wiring…

A hashed user store wired into HTTP Basic, five ways to resolve a tenant per request, and Prometheus metrics with a health endpoint for TsgcHTTPRESTServer…

TsgcHTTPRESTServer is a new HTTP server component for REST APIs, adding CORS, metrics and health endpoints and multi-tenancy on top of TsgcHTTPServer…

OpenSSL can now be linked directly inside your sgcWebSockets executable instead of being loaded at runtime from libcrypto and libssl DLLs. Add one unit to the uses clause and there is nothing else to configure…

sgcWebSockets adds TCPKeepAlive and KeepAliveTimeout to the IOCP and EPOLL server engines, closing connections whose peer silently disappeared instead of leaving them open forever…

sgcQUIC brings HTTP/3 to Delphi and C++ Builder with TsgcHTTP3Client and TsgcHTTP3Server, running HTTP semantics over QUIC with QPACK header compression, every verb, async requests and Alt-Svc discovery…

sgcQUIC adds the QUIC transport protocol to Delphi and C++ Builder with TsgcQUICClient and TsgcQUICServer, built on the native OpenSSL 3.5 QUIC engine with TLS 1.3, multiplexed streams and 0-RTT…

Serve sgcHTML pages from any WebBroker application and from DataSnap servers, with live WebSocket updates on the same port as your DataSnap REST endpoints…

Three new sgcHTML admin components: Presence for a live who's-online roster, RolesPermissions for a grant matrix, and UserManagement for a full user administration table…

Six new sgcHTML feedback and layout components: Badge, PDFViewer, ContextMenu, ProgressBar, JobProgress and LogViewer — telling a visitor what's happening right now…
