Major Performance Improvements

This release includes significant performance optimizations across multiple areas:

• Lazy BTF Decoding: BTF types are now decoded on-demand rather than all upfront, dramatically reducing memory usage and load times
• Faster Object Opening: Opening Maps and Programs from fd/id/pin is significantly faster through minimal info retrieval
• Improved Statistics Access: New Program.Stats() method allows querying runtime statistics without fetching full ProgramInfo

CO-RE Improvements

• Full Kernel Module Support: CO-RE relocations now work against all kernel modules, not just vmlinux

Build System and Toolchain Updates

• LLVM Toolchain: Updated to support LLVM 14, 17, and 20 (dropped LLVM 11 support)

Enhanced Map Support

• BTF Declaration Tags: Added MapSpec.Tags field for reading btf_decl_tag attributes set on maps
• Better Error Handling: Improved BPF_F_NO_PREALLOC hints and warnings for map types that require this flag

Assembly and Instruction Handling

• Atomic Operations: Complete support for all atomic operations beyond just atomic add

Memory and Variable Access

• New Accessors: Added accessor methods for values represented by Variable and Memory types

Windows Support Improvements

• Path Canonicalization: Fixed pin path handling to work with eBPF for Windows path canonicalization rules

Bug Fixes

• Map Batch Operations: Fixed value unmarshaling for partial batch operations in BatchLookup and BatchLookupDelete (#​1741)
• Assembly Validation: Return InvalidOpCode for StoreImm with DWord size (#​1767)
• Builtin Function Calls: Allow negative constants for builtin function calls (#​1797)
• CO-RE Module Types: Perform CO-RE against all kernel module types (#​1511)
• Pin API: Made WalkDir harder to misuse and added Windows support (#​1652)
• Struct Layout: Emit structs.HostLayout in GoFormatter (#​1686)

Compatibility Notes

• Minimum eBPF for Windows: Now requires eBPF for Windows 0.21.0 or later
• LLVM 11 Dropped: No longer supports LLVM 11 (required for declaration tag support)
