Changelog¶

All notable changes to pyaota will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Encrypted answer embedding in QR codes (--encode-answers-in-qr flag on build) — correct answers are encrypted and stored directly in each answer sheet’s QR code. A random per-exam-set key is generated at build time and stored in answersheet_layout.json; the grader decrypts automatically using that file, making the answer-key CSV optional for day-of grading. Old answer sheets without embedded answers continue to work unchanged via CSV lookup.
Interactive grading (--interactive flag on grade) — when a QR code, student-ID field, or answer bubble cannot be read automatically, pyaota pauses and prompts the operator at the terminal to supply the missing value. For unanswered questions a matplotlib window displays the bubble row so the operator can confirm or override the detected answer.

Compact MCQ choice layout — choices are automatically arranged in two columns when all choice texts are short enough.
True/False question simplification — T/F questions no longer render a separate choices block; the stem is prefixed with bold True (T) / False (F).
T/F correct-answer highlighting — in compile-dump the correct answer for T/F questions is visually indicated with a filled circle, consistent with MCQ behavior.
Greedy topic redistribution — get_random_selection no longer errors when a topic has fewer questions than the uniform quota; available questions are redistributed across better-stocked topics so the total count is always met.
--font-size {10pt,11pt,12pt} option on build and compile-dump (default 12pt).
--question-spacing <LENGTH> option on build and compile-dump (default 24pt).
--bubble-font-size <PT> option on build and make-answersheet (default 8.0).
--odd-page-answersheet flag on build and make-answersheet.
--rasterize flag on build and make-answersheet.
Full command line echoed at DEBUG level to the diagnostic log at startup.

Excess vertical space between a code-block stem and the choices list in MCQs.
Answer sheet page always renders at 12 pt regardless of the --font-size setting.
