ChangeLog (since 02 May 2019)

14 August 2025: added encrypted version of Oregon Trail ('Prize in diabolical logistics').
06 August 2025: added my two winning entries in 2024 (contest started at end of 2024, the 40th year anniversary of the IOCCC!).
25 May 2024: as of quite some time back I removed the 2019 entries: I did not like them that much and did not want them published therefore. I do not know the date that this was done, however, as I have been very busy and I forgot all about it. Very busy includes helping the IOCCC judges with the website, fixing old entries to work with modern systems and writing some tools for them for the next contest, all of which will probably be noted in different pages here in time.
18 Jul 2023: removed tweets from pages and add commentary to Enigma machine entry of 2020.
25 Feb 2023: The 2020 entries on the IOCCC website and the GitHub repo work now as of last year due to a pull request fixing it.
23 Jul 2021: Fix incorrect statement in my comments on the 'Don't tread on me award' entry (mixed the meaning of two variables SHED and SHEDS).
22 Jul 2021: Add comments of interest on my Snake game and Ilya Kurdyukov's Snake inspired by my winning entry.
14 Jul 2021: Embed video tweet demo of Enigma simulator entry.
09 January 2021: Update 2020 entry pages (the 2020 index and the two winning entries). More will follow in time but I do not know when that is as I have a lot going on right now (and I know I'm far from alone!).
26 July 2020: Two of my 2020 entries won! More information will follow in due course but the index page of the 2020/ subdirectory has tweets for both entries and the individual subdirectories have the respective tweet as well.
13 May 2019: Add two (of three) (lost) entries for 2019 plus a congratulations to the winners.
08 May 2019: Images and overflowing text should now be responsive (scale down in size and break the word to the next line).
02 May 2019: Greatly simplify several sections by removing redundancy and also reorganised the sections a bit.
02 May 2019: Update errata (clarify something about Xcode; requires command line developer tools but does not require Xcode proper).
