+# OpenZFS 2.3.0 Features in ZFSWrapper
+
+This document describes the new OpenZFS 2.3.0 features that have been added to the ZFSWrapper library.
+
+## Overview
+
+OpenZFS 2.3.0 introduced several significant features that enhance performance, flexibility, and functionality:
+
+- **RAIDZ Expansion**: Add devices to existing RAIDZ vdevs without downtime
+- **Direct I/O**: Bypass ARC for better performance with fast storage devices  
+- **Enhanced Deduplication**: Better management of deduplication with quotas and statistics
+- **Long Filename Support**: Support for filenames up to 1023 characters
+- **Wait Operations**: Wait for pool operations to complete
+
+## API Reference
+
+### ZFSManager Class (High-Level API)
+
+#### RAIDZ Expansion
+```cpp
+// Expand a RAIDZ vdev by adding a new device
+bool expandRaidz(const std::string& poolName, const std::string& raidzName, const std::string& newDevice);
+
+// Check if a pool is currently expanding RAIDZ
+bool isPoolRaidzExpanding(const std::string& poolName);
+```
+
+#### Direct I/O Support
+```cpp
+// Set Direct I/O mode for a filesystem
+bool setDirectIO(const std::string& filesystemName, bool enabled);
+```
+
+#### Enhanced Deduplication
+```cpp
+// Get deduplication statistics for a pool
+bool getDedupStats(const std::string& poolName, std::uint64_t& tableSize, std::uint64_t& tableCached);
+
+// Set deduplication table quota for a pool  
+bool setDedupQuota(const std::string& poolName, std::uint64_t quota);
+```
+
+### ZPool Class (Low-Level API)
+
+#### RAIDZ Expansion
+```cpp
+// Add devices to an existing RAIDZ vdev
+int raidzExpand(const std::string& raidz_name, const std::string& new_device);
+
+// Get RAIDZ expansion statistics
+struct RaidzExpandStat {
+    uint64_t res_state;                // Current state of expansion
+    uint64_t res_start_time;           // Start time of expansion  
+    uint64_t res_end_time;             // End time of expansion
+    uint64_t res_to_reflow;            // Total bytes to reflow
+    uint64_t res_reflowed;             // Bytes already reflowed
+    uint64_t res_waiting_for_resilver; // Waiting for resilver
+};
+
+bool getRaidzExpandStats(RaidzExpandStat& stats) const;
+bool isRaidzExpanding() const;
+```
+
+#### Enhanced Deduplication
+```cpp
+// Get deduplication table size for this pool
+std::uint64_t getDedupTableSize() const;
+
+// Get deduplication table quota for this pool
+std::uint64_t getDedupTableQuota() const;
+
+// Get cached deduplication data amount for this pool
+std::uint64_t getDedupCached() const;
+
+// Set deduplication table quota for this pool
+int setDedupTableQuota(std::uint64_t quota);
+```
+
+#### Wait Operations
+```cpp
+// Wait for RAIDZ expansion to complete
+int waitForRaidzExpansion();
+
+// Wait for scrub to complete
+int waitForScrub();
+```
+
+### ZFileSystem Class (Low-Level API)
+
+#### Direct I/O Support
+```cpp
+enum class DirectIOMode {
+    disabled = 0,    // Direct I/O disabled (default)
+    standard = 1,    // Direct I/O enabled for large I/O
+    always = 2       // Direct I/O always enabled
+};
+
+// Set Direct I/O mode for this filesystem
+int setDirectIOMode(DirectIOMode mode);
+
+// Get Direct I/O mode for this filesystem  
+DirectIOMode getDirectIOMode() const;
+
+// Check if Direct I/O is supported for this filesystem
+bool isDirectIOSupported() const;
+```
+
+#### Long Filename Support
+```cpp
+// Check if long filenames (up to 1023 chars) are supported
+bool isLongNameSupported() const;
+```
+
+## Usage Examples
+
+### Example 1: RAIDZ Expansion
+```cpp
+zfs::ZFSManager manager;
+
+// Check if expansion is in progress
+if (manager.isPoolRaidzExpanding("mypool")) {
+    std::cout << "Pool is currently expanding" << std::endl;
+}
+
+// Add a device to expand RAIDZ
+if (manager.expandRaidz("mypool", "raidz-0", "/dev/disk3")) {
+    std::cout << "RAIDZ expansion initiated" << std::endl;
+}
+```
+
+### Example 2: Direct I/O for NVMe Performance
+```cpp
+zfs::ZFSManager manager;
+
+// Enable Direct I/O for better NVMe performance
+if (manager.setDirectIO("mypool/dataset", true)) {
+    std::cout << "Direct I/O enabled" << std::endl;
+}
+```
+
+### Example 3: Deduplication Management
+```cpp
+zfs::ZFSManager manager;
+
+// Get deduplication statistics
+std::uint64_t tableSize, tableCached;
+if (manager.getDedupStats("mypool", tableSize, tableCached)) {
+    std::cout << "Dedup table: " << tableSize << " bytes" << std::endl;
+    std::cout << "Cached: " << tableCached << " bytes" << std::endl;
+}
+
+// Set 1GB deduplication quota
+manager.setDedupQuota("mypool", 1024ULL * 1024 * 1024);
+```
+
+### Example 4: Wait for Operations
+```cpp
+zfs::LibZFSHandle lib;
+auto pool = lib.pool("mypool");
+
+// Start a scrub and wait for completion
+pool.scrub();
+pool.waitForScrub();
+std::cout << "Scrub completed" << std::endl;
+
+// Wait for RAIDZ expansion if in progress
+if (pool.isRaidzExpanding()) {
+    pool.waitForRaidzExpansion();
+    std::cout << "RAIDZ expansion completed" << std::endl;
+}
+```
+
+## Compilation Requirements
+
+To use these features, ensure you have:
+
+1. **OpenZFS 2.3.0 or later** installed
+2. **macOS 11.0 or later** (for ARM64 support)
+3. **CMake 3.10 or later**
+4. **C++17 compatible compiler**
+
+The features are automatically detected at compile time and enabled via CMake options:
+
+```bash
+cmake .. -DZFSW_HAS_ZPOOL_STATUS_COMPATIBILITY_ERR=ON \
+         -DZFSW_HAS_ZPOOL_STATUS_INCOMPATIBLE_FEAT=ON
+```
+
+## Notes and Limitations
+
+1. **RAIDZ Expansion**: This is a long-running operation. Use `waitForRaidzExpansion()` carefully in production code.
+
+2. **Direct I/O**: Best suited for fast storage devices like NVMe. May not provide benefits on slower devices.
+
+3. **Deduplication**: Monitor memory usage when enabling deduplication, especially with quotas.
+
+4. **Long Filenames**: While supported, very long filenames may impact performance.
+
+5. **Platform Support**: These features are tested on macOS ARM64. Linux and other platforms should work but may require additional testing.
+
+## Building the Examples
+
+```bash
+cd examples
+mkdir build && cd build
+cmake ..
+make openzfs_2_3_0_demo
+./openzfs_2_3_0_demo
+```
+
+## Error Handling
+
+All functions follow the existing ZFSWrapper error handling patterns:
+
+- **High-level API** (ZFSManager): Returns `bool` for success/failure, prints errors to stderr
+- **Low-level API** (ZPool/ZFileSystem): Returns `int` error codes (0 = success) or throws exceptions
+
+Always check return values and handle exceptions appropriately in production code.
