+Python, Node and WASM are *native* Rust bindings (PyO3 / napi-rs /
+wasm-bindgen). The C ABI is the *hub* every other C-capable language links
+against: it builds to a `cdylib`/`staticlib` plus a generated `wickra.h`, and
+downstream languages link that one artifact rather than each re-wrapping the
+core. C and C++ link it directly; the **C# / .NET** binding (`bindings/csharp`,
+on NuGet), the **Go** binding (`bindings/go`, cgo) and the **R** binding
+(`bindings/r`, `.Call`) are generated from `wickra.h`, with Java planned the

-## [Unreleased]
+## [0.7.8] - 2026-06-09
+### Added
+- **R binding (`bindings/r`)** — an R package reaching the C ABI hub through R's
+  native `.Call` interface, exposing all 514 indicators as constructors that
+  return a `wickra_indicator` object with `update`/`batch`/`reset` methods. The
+  C glue and R wrappers are generated from `wickra.h`; the native handle is freed
+  by a registered finalizer. Ships a full example suite mirroring the C, C# and
+  Go examples; distributed for r-universe / source install.
+
+## [0.7.7] - 2026-06-09
+### Added
+- **Go binding (`bindings/go`)** — a cgo binding over the C ABI hub exposing all
+  514 indicators as idiomatic types with `New<Indicator>` constructors and
+  `Update`/`Batch`/`Reset`/`Close` methods, generated from `wickra.h`. Handles are
+  freed by `Close()` with a `runtime.SetFinalizer` backstop. Ships a full example
+  suite mirroring the C and C# examples; distributed as a subdirectory module
+  (`go get github.com/wickra-lib/wickra/bindings/go`).
+
+## [0.7.6] - 2026-06-09
+### Added
+- **C# / .NET binding (`bindings/csharp`)** — the first language stecker on the
+  C ABI hub. Exposes all 514 indicators as idiomatic `IDisposable` classes via
+  `[LibraryImport]` source-generated P/Invoke, generated from `wickra.h`. Ships
+  on NuGet as `Wickra` with prebuilt native libraries for six target triples
+  (win/linux/osx × x64/arm64), plus a full example suite mirroring the C examples.
+
+## [0.7.5] - 2026-06-09
+### Added
+- **C ABI (`bindings/c`)** — a `cdylib` + `staticlib` plus a generated
+  `include/wickra.h` exposing all 514 indicators and 10 bar builders over an
+  opaque-handle C ABI: the hub any C-capable language (C, C++, Go, C#, Java, R)
+  links against, complementing the native Python/Node/WASM bindings. Ships a
+  full example suite (streaming, backtest, multi-timeframe, OpenMP parallel
+  fan-out, three educational strategies, and Binance fetch/live over `curl`)
+  mirroring the other bindings, plus an optional `wickra.hpp` C++ RAII wrapper.

+**Streaming-first technical indicators for C and C++. A prebuilt shared/static
+library plus a generated `wickra.h` — no system dependencies.**
+
+Wickra is a multi-language technical-analysis library with a Rust core and
+bindings for Python, Node.js and WebAssembly, plus a C ABI for C/C++, C#, Go, R and any
+other C-capable language. Every indicator is an O(1)
+streaming state machine, so live trading bots and historical backtests share
+the exact same implementation. This package is the **C ABI hub**: it compiles the
+core to a C-compatible shared/static library plus a generated header, so any
+C-capable language (C, C++, Go, C#, Java, R) links against one artifact instead
+of re-wrapping every indicator natively.
+
+## Install
+
+Grab the prebuilt header + library for your platform from the
+[GitHub releases](https://github.com/wickra-lib/wickra/releases) — each archive
+has `wickra.h`, the optional `wickra.hpp` C++ wrapper, and the shared/static
+library — or build from source:
+
+```bash
+cargo build -p wickra-c --release
+# -> target/release/libwickra.{so,dylib} or wickra.dll (+ import lib) + a staticlib
+```
+
+Then compile against the header and link the library
+(`cc app.c -I include -L lib -lwickra -lm -o app`).
+
+## Quick start
+
+```c
+#include "wickra.h"
+
+struct Rsi *rsi = wickra_rsi_new(14);              /* NULL on invalid params */
+for (size_t i = 0; i < n; ++i) {
+    double v = wickra_rsi_update(rsi, prices[i]);  /* NaN during warmup       */
+    if (v == v && v > 70.0)                        /* v == v is the NaN check */
+        printf("overbought\n");
+}
+wickra_rsi_free(rsi);                              /* exactly once per _new   */
+```
+
+Every indicator is an opaque handle with the same five functions —
+`_new` / `_update` / `_batch` / `_reset` / `_free`. `update` is O(1); there is no
+RAII across the C boundary, so each `_new` needs exactly one `_free`, and every
+function is NULL-safe (a NULL handle yields `NaN` or a no-op, never a crash).
+Multi-output indicators (MACD, Bollinger, ADX, …) take a pointer to a `#[repr(C)]`
+struct and return a `bool`. The optional `wickra.hpp` wraps any handle in a
+move-only `wickra::Handle` for exception-safe C++ lifetimes.
+
+## Documentation
+
+The full indicator catalogue, guides, quickstarts, and API reference live in
+the main repository and documentation site:
+
+- **Repository & full indicator list:** <https://github.com/wickra-lib/wickra>
+- **Docs** (C quickstart, cookbook, TA-Lib migration): <https://docs.wickra.org/Quickstart-C>
+- **Runnable examples:** [`examples/c/`](https://github.com/wickra-lib/wickra/tree/main/examples/c)
+
+Wickra ships native bindings for Python, Node.js, WebAssembly and Rust, plus this
+C ABI hub that any C-capable language (C, C++, Go, C#, Java, R) links against —
+all exposing the same indicators from the shared Rust core.
+
+## Disclaimer
+
+Wickra is an indicator toolkit, not a trading system. The values it computes
+are deterministic transforms of the input data — they are not financial advice
+and do not predict the market. Any use in a live trading context is at your own
+risk. The library is provided **as is**, without warranty of any kind.

+
+**Streaming-first technical indicators for .NET. `dotnet add package Wickra` —
+prebuilt native library, no system dependencies.**
+
+Wickra is a multi-language technical-analysis library with a Rust core and
+bindings for Python, Node.js and WebAssembly, plus a C ABI for C/C++, C#, Go, R and any
+other C-capable language. Every indicator is an O(1)
+streaming state machine, so live trading bots and historical backtests share
+the exact same implementation. This package is the .NET binding; it consumes the
+C ABI hub through `[LibraryImport]` P/Invoke and exposes all 514 streaming-first
+indicators as idiomatic `IDisposable` classes.
+
+## Install
+
+```bash
+dotnet add package Wickra
+```
+
+The native library ships prebuilt per platform (Linux, macOS, Windows — x64 and
+arm64) under `runtimes/<rid>/native/`, selected automatically. There is nothing
+to compile. Targets .NET 8 and later.
+
+## Quick start
+
+```csharp
+using Wickra;
+
+// Batch: run an indicator over a whole series (NaN at warmup positions).
+var prices = Enumerable.Range(0, 1000).Select(i => 100.0 + i * 0.1).ToArray();
+using var sma = new Sma(20);
+double[] values = sma.Batch(prices);
+
+// Streaming: the same indicator, fed tick by tick in O(1).
+using var rsi = new Rsi(14);
+foreach (var price in liveFeed)
+{
+    var value = rsi.Update(price); // NaN during warmup, no recomputation
+    if (double.IsFinite(value) && value > 70)
+    {
+        Console.WriteLine("overbought");
+    }
+}
+```
+
+`Batch(prices)` and feeding the same prices through `Update()` produce identical
+values — the equivalence is enforced by the test suite. Multi-output indicators
+(MACD, Bollinger, ADX, …) return a nullable `record struct`, `null` while warming up.
+
+## Documentation
+
+The full indicator catalogue, guides, quickstarts, and API reference live in
+the main repository and documentation site:
+
+- **Repository & full indicator list:** <https://github.com/wickra-lib/wickra>
+- **Docs** (quickstarts, cookbook, TA-Lib migration): <https://docs.wickra.org>
+- **Runnable examples:** [`examples/csharp/`](https://github.com/wickra-lib/wickra/tree/main/examples/csharp)
+
+Wickra ships native bindings for Python, Node.js, WebAssembly and Rust, plus a
+C ABI hub that any C-capable language (C, C++, Go, C#, Java, R) links against —
+all exposing the same indicators from the shared, `unsafe`-forbidden Rust core.
+
+## Disclaimer
+
+Wickra is an indicator toolkit, not a trading system. The values it computes
+are deterministic transforms of the input data — they are not financial advice
+and do not predict the market. Any use in a live trading context is at your own
+risk. The library is provided **as is**, without warranty of any kind.

+
+**Streaming-first technical indicators for Go, over the Wickra C ABI hub via cgo.**
+
+Wickra is a multi-language technical-analysis library with a Rust core and
+bindings for Python, Node.js and WebAssembly, plus a C ABI for C/C++, C#, Go and
+any other C-capable language. Every indicator is an O(1) streaming state machine,
+so live trading bots and historical backtests share the exact same
+implementation. This package is the Go binding; it consumes the C ABI hub through
+cgo and exposes all 514 streaming-first indicators as idiomatic types.
+
+## Install
+
+```bash
+go get github.com/wickra-lib/wickra/bindings/go
+```
+
+The binding uses cgo, so a C compiler is required, and it links against the
+prebuilt Wickra C ABI library. Build that library from the workspace and stage
+it under this package's `lib/` directory:
+
+```bash
+cargo build -p wickra-c --release
+cp target/release/libwickra.so    bindings/go/lib/   # Linux
+cp target/release/libwickra.dylib bindings/go/lib/   # macOS
+cp target/release/wickra.dll      bindings/go/lib/   # Windows (also on PATH at run time)
+```
+
+On Linux and macOS the library path is baked in via rpath; on Windows the DLL
+must be discoverable at run time (next to the executable or on `PATH`).
+
+## Quick start
+
+```go
+package main
+
+import (
+	"fmt"
+
+	wickra "github.com/wickra-lib/wickra/bindings/go"
+)
+
+func main() {
+	// Batch: run an indicator over a whole series (NaN at warmup positions).
+	prices := make([]float64, 1000)
+	for i := range prices {
+		prices[i] = 100.0 + float64(i)*0.1
+	}
+	sma, _ := wickra.NewSma(20)
+	defer sma.Close()
+	values := sma.Batch(prices)
+
+	// Streaming: the same indicator, fed tick by tick in O(1).
+	rsi, _ := wickra.NewRsi(14)
+	defer rsi.Close()
+	for _, price := range prices {
+		value := rsi.Update(price) // NaN during warmup, no recomputation
+		if value > 70 {
+			fmt.Println("overbought")
+		}
+	}
+	_ = values
+}
+```
+
+`Batch(prices)` and feeding the same prices through `Update()` produce identical
+values — the equivalence is enforced by the test suite. Multi-output indicators
+(MACD, Bollinger, ADX, …) return `(Output, bool)`, with `false` while warming up.
+Every indicator owns a native handle freed by `Close()`; a finalizer is wired as
+a backstop, but call `Close()` (e.g. with `defer`) to release memory promptly.
+
+## Documentation
+
+The full indicator catalogue, guides, quickstarts, and API reference live in the
+main repository and documentation site:

+Wickra ships native bindings for Python, Node.js, WebAssembly and Rust, plus a
+C ABI hub that any C-capable language (C, C++, C#, Go, Java, R) links against —
+all exposing the same indicators from the shared, `unsafe`-forbidden Rust core.
+
+## Disclaimer
+
+Wickra is an indicator toolkit, not a trading system. The values it computes are
+deterministic transforms of the input data — they are not financial advice and
+do not predict the market. Any use in a live trading context is at your own risk.
+The library is provided **as is**, without warranty of any kind.

+
+**Streaming-first technical indicators for R, over the Wickra C ABI hub via `.Call`.**
+
+Wickra is a multi-language technical-analysis library with a Rust core and
+bindings for Python, Node.js and WebAssembly, plus a C ABI for C/C++, C#, Go, R
+and any other C-capable language. Every indicator is an O(1) streaming state
+machine, so live trading and historical backtests share the exact same
+implementation. This package is the R binding; it reaches the C ABI hub through
+R's native `.Call` interface and exposes all 514 indicators as constructors that
+return a lightweight `wickra_indicator` object.
+
+## Install
+
+The package compiles a thin C glue layer (`.Call`) against the prebuilt Wickra
+C ABI library, so a C toolchain (Rtools on Windows) is required, plus the C ABI
+header and library. Build the library from the workspace, then install the
+package pointing at it:
+
+```bash
+cargo build -p wickra-c --release
+WICKRA_INCLUDE_DIR="$PWD/bindings/c/include" \
+WICKRA_LIB_DIR="$PWD/target/release" \
+R CMD INSTALL bindings/r
+```
+
+On Windows the C ABI DLL is bundled into the package and put on the load path
+automatically; on Linux and macOS the library path is baked in via rpath.
+
+## Quick start
+
+```r
+library(wickra)
+
+# Batch: run an indicator over a whole series (NaN at warmup positions).
+prices <- 100 + (0:999) * 0.1
+sma <- Sma(20)
+values <- batch(sma, prices)
+
+# Streaming: the same indicator, fed one observation at a time in O(1).
+rsi <- Rsi(14)
+for (price in prices) {
+  v <- update(rsi, price) # NaN during warmup
+  if (!is.na(v) && v > 70) message("overbought")
+}
+
+# Multi-output indicators return a named vector (NA while warming up).
+macd <- MacdIndicator(12, 26, 9)
+update(macd, 42) # c(macd = NA, signal = NA, histogram = NA)
+```
+
+`batch(ind, prices)` and feeding the same prices through `update()` produce
+identical values — the equivalence is enforced by the test suite. Candle-input
+indicators take the OHLCV fields plus a timestamp, e.g.
+`update(atr, open, high, low, close, volume, timestamp)`. The native handle is
+freed automatically when the object is garbage-collected.
+
+## Documentation
+
+The full indicator catalogue, guides, quickstarts, and API reference live in the
+main repository and documentation site:
+
+- **Repository & full indicator list:** <https://github.com/wickra-lib/wickra>
+- **Docs** (quickstarts, cookbook, TA-Lib migration): <https://docs.wickra.org>
+- **Runnable examples:** [`examples/r/`](https://github.com/wickra-lib/wickra/tree/main/examples/r)
+
+Wickra ships native bindings for Python, Node.js, WebAssembly and Rust, plus a
+C ABI hub that any C-capable language (C, C++, C#, Go, Java, R) links against —
+all exposing the same indicators from the shared, `unsafe`-forbidden Rust core.
+
+## Disclaimer
+
+Wickra is an indicator toolkit, not a trading system. The values it computes are
+deterministic transforms of the input data — they are not financial advice and
+do not predict the market. Any use in a live trading context is at your own risk.
+The library is provided **as is**, without warranty of any kind.
