Doom Vanille

Doom Vanille is a source port created by Alexandre-Xavier Labonté-Lamoureux, otherwise known as AXDOOMER. It is derived from PCDoom-v2, itself a port of Linux Doom to DOS. It aims to enhance the stock executable with new features and fixes to reduce the risk of crashes, premature program exits and certain visual problems, while maintaining full compatibility with the original executable, including the usage of the original DMX sound engine.

It has a version that increases static limits and adheres to the Doom2-plus template of raising limits, allowing several WADs to be playable in the vanilla engine that would previously require a limit-removing source port to be run.

History
The first release was based on PCDoom on May 29, 2017 as version 666. It introduced new parameters for Doom:, , , and. Development for the port was slow, with a second release called version 667 on November 20, 2018. Version 668 took almost a year to release on October 14, 2019. It fixed a bug where grid lines were disappearing near the automap boundary and the executable with the extended limits is improved so it has less chance of crashing when saving the game.

It was in 2020 when Doom Vanille picked up pace. Version 669 released on May 24, 2020 is a maintenance release without changes, but 670 could be considered a major version. Released on May 30, 2020, it fixes a bug that prevented the Phase 1 IWAD of FreeDoom from loading, but it also included a second executable, based on Doom2-plus limits by Andrey Budko (entryway).

The last and current release is version 671, from June 24, 2020. It contained the fix for the buffer overflow in and only comes with its static limits raised per Doom2-plus.
