SQLite has a worse-is-better philosophy about automatically converting
between different data types, such as strings and floating point numbers:
https://www.sqlite.org/quirks.html#flexible_typing
This means querying for the string "1.10" in a given column can return
rows where the column is actually the string "1.1", since SQLite imagines
you might be talking about the number 1.1, rather than the string you
actually requested.
This "feature" became a problem for Meteor after we published Meteor 1.10,
which caused SQLite to return multiple rows for the getReleaseVersion
query, including both Meteor 1.10 and Meteor 1.1 (which is ancient, from
March 2015).
While this behavior seems completely indefensible, the SQLite
documentation clearly does not consider it a bug, which forces us to work
around the consequences by double-checking the queried results with the
filterExactRows helper function.
Unfortunately, this conversion triggered an error due to one of the
shortcomings of the Babel implementation of TypeScript:
SyntaxError: /tools/tool-env/profile.ts: Namespace not marked type-only declare. Non-declarative namespaces are only supported experimentally in Babel. To enable and review caveats see: https://babeljs.io/docs/en/babel-plugin-transform-typescript

Once Windows developers update to a 64-bit version of Meteor 1.6, they may
still wish to run apps using older versions of Meteor where only 32-bit
builds of meteor-tool are available. This commit makes that possible.
These changes introduce dual Mongo support into the Meteor
Tool. 32-bit Mongo (3.2.15) will be used by Meteor when the
Tool is run on a 32-bit OS (32-bit Linux and Windows). 64-bit
Mongo (3.4.9) will be used when the Tool is run on a 64-bit
OS (64-bit Linux, Windows and macOS).
