🎉 libFPC v1.0.0 – First Official Release

We’re excited to announce libFPC v1.0.0, the first official release of the library that brings runtime access to the FreePascal compiler in a powerful, dynamic way.

This release introduces full support for in-memory compilation, DLL/EXE execution, source-from-string, and more!

🚀 Highlights

• ✅ In-memory DLL loading: libfpc_deps.dll is now loaded directly from memory—no disk I/O.
• 📜 Compile from string or file: Thanks to the new SetProjectSource, you can now pass source directly as a string.
• 🔍 Get status and diagnostics: Retrieve error messages, counts, and compiler stats programmatically.
• ⚙️ Add metadata: Inject version info, icons, and manifests into your EXE or DLL.
• 🧠 In-memory execution: Compile and run executables or DLLs directly from memory, ideal for plugins and sandboxing.

🧠 Core Enhancements

• libfpc_deps.dll now loads directly from memory
• 🔄 Renamed SetPrintEvent ➜ SetPrintCallback
• ➕ Added:
  • GetStats
  • GetErrorCount
  • GetError(Index)

Easily inspect compilation errors and status programmatically.

📝 Source Management

• 🆕 Introduced lfpProjectSource type
• 🔄 Replaced SetProjectFilename with:
