Oct 1, 2025October 2025: LearnPress/learnpress feature enhancement focused on improving LaTeX content handling and data integrity. Implemented a configurable add_slashes parameter in LP_Helper::sanitize_params_submitted to preserve backslashes in content types like LaTeX math syntax, adjusted the default unslash behavior to better support LaTeX submissions, and updated documentation to clarify when to disable unslash for LaTeX content. These changes reduce data loss risk, improve editing workflows (e.g., EditQuestionAjax), and set the stage for future content-safety improvements. No separate major bug fixes recorded this month; effort centered on feature refinement, docs, and maintainability.
