[ANN] OneLuaPro 5.4.8.3 – Event-driven Mul ti-threading and SQLite3+sqlean Integration

Hi everyone,

*OneLuaPro 5.4.8.3* has been released. This update introduces significant 
changes to the internal handling of asynchronous tasks and provides native 
database capabilities.

*Downloads:* https://github.com/OneLuaPro/OneLuaPro/releases/tag/v5.4.8.3

*Technical Updates:*

   - *wxLanesBridge Implementation:* Support for multi-threaded GUI 
   applications is now facilitated by the wxLanesBridge 
   <https://github.com/OneLuaPro/wxlanesbridge> module. This component 
   bridges the gap between wxLua <https://github.com/OneLuaPro/wxlua> and Lua 
   Lanes <https://github.com/OneLuaPro/lanes>. The traditional bottleneck 
   of timer-based polling has been eliminated; instead, an event-driven 
   approach is utilized where worker threads communicate directly with the 
   main GUI thread via postEvent(). This ensures immediate UI responsiveness 
   and reduced CPU overhead.


   - *DistroCheck Tool:* A new utility for verifying distribution integrity 
   is included. Developed as a reference implementation for wxLanesBridge, it 
   demonstrates how intensive I/O operations can be offloaded to worker 
   threads without blocking the wxLua event loop. The implementation details 
   and the postEvent() signaling logic can be examined in the OneLuaPro distro 
   repository <https://github.com/OneLuaPro/distro>.


   - *OneLuaPro Help Center:* Centralized documentation is now available 
   through a dedicated Help Center, serving as the primary hub for all 
   technical documentation.


   - *SQLite3 + sqlean Integration:* Database support is provided via a 
   reimplementation of lsqlite3 <https://github.com/OneLuaPro/lsqlite3>, 
   utilizing the most recent SQLite3 builds. Notably, the full suite of sqlean 
   extensions (e.g., crypto, fileio, math, text) is integrated, providing a 
   comprehensive set of functions for advanced data manipulation directly 
   within SQL.


   - *Executables:* All former .bat files within the bin/ directory have 
   been replaced by native executables to ensure cleaner process handling and 
   user experience.
