== Protocol Evolution: 1.23 to 1.9 ==

The Hotline protocol underwent significant internal changes as it scaled from a small hobbyist tool to a professional-grade communication suite.

=== The 1.2x Era (Legacy Basics) ===
The 1.23 protocol was the "foundation." It established the core TRTP handshake and the concept of Big-Endian binary headers.
* '''Features:''' Basic Chat (Trans 105), Messaging, and flat File lists.
* '''Limitations:''' Very limited permission sets and no news threading.
* '''Key Header:''' The early headers were often shorter and lacked the flexibility for complex sub-parameters seen in later versions.

=== The 1.5x Era (The "News" Revolution) ===
Around April 1999, the protocol underwent a major shift, specifically in how News was handled.
* '''Introduction of Bundles:''' Version 1.5 introduced '''Field 323''' (News Category List Data), allowing servers to group news into folders (Bundles) rather than just a flat list.
* '''The GUID Shift:''' This era saw the introduction of Global Unique Identifiers for news categories to prevent conflicts during server synchronization.
* '''Banner Support:''' Version 1.5 introduced the logic to request banners (Trans 122) via HTTP or binary transfer.

=== The 1.8x - 1.9 Era (The Modern Standard) ===
This version is what most modern clients and your current wiki documentation focus on. It refined the protocol for high-traffic environments.
* '''Advanced Permissions:''' The [[AccessPriviledges|64-bit Access Bitmap]] was fully fleshed out, adding granular control over things like "News Delete Category" and "View Drop Boxes."
* '''Flattened File Objects (FILP):''' The file transfer logic was finalized to support cross-platform metadata (INFO vs DATA forks), allowing Mac and Windows users to exchange files with their respective metadata intact.
* '''Enhanced Login (Version 151):''' The login sequence was updated to include mandatory Agreement checks (Trans 109/121) and community-driven Banner IDs.
