Fenris Creations begins moving EVE Online's 2.4 million lines of Python 2.7 to Python 3 and deploys the first stage to Tranquility

Sources: primary, discussion
Summary: Fenris Creations, named as the publisher throughout the source, began migrating EVE Online's 2.4 million lines of Python 2.7 to Python 3 and deployed the first stage to the Tranquility cluster. The published scan numbers state that 95.9 percent of files already compiled under both versions. About 20,000 lines compile under both and behave differently.
Why it matters: The scan numbers are the reusable part for anyone scoping a similar migration, because the silent behaviour differences, not the compile failures, are what the file-level pass rate hides.
