Changes/additions:

ES6 code generated
types: https://github.com/olado/doT/blob/v2/doT.d.ts
varname option renamed to argName
support templates without explicit context "it" - the list of properties should be passed as array to argName option, template function will expect an object and will destructure it into multiple arguments - so it is nearly zero-cost:

const tmpl = doT.template("{{=foo}}{{=bar}}", {argName: ["foo", "bar"]})
tmpl({foo: 1, bar: 2}) // "12"

partial options can be passed, global options object will not be available in the next release.
custom encoders:
- syntax {{<encoder name>! it.foo}}, encoders passed to encoders option object ( is any valid JS identifier) as functions (or as code strings in selfContained: true mode).
- HTML encoding with syntax {{! it.foo }} requires passing {encoders: {"": require("dot/encodeHTML")}} options
type safe interpolation (maybe % should be dropped...):
- {{%n= it.foo}} - it.foo must be number (or exception will be thrown)
- {{%s= it.foo}} - string
- {{%b= it.foo}} - boolean
support iterables for {{~iter:x}} and {{~iter:x:i}} syntaxes (now uses for-of loop).
syntax is no longer in options
configurable delimiters:
- e.g. {delimiters: {start: "<%", end: "%>"}} via options to change for one template
- or setDelimiters({start: "<%", end: "%>"}) to change globally
reduces internal variables names usage, two configurable name prefixes are used, can be changed via options (internalPrefix: "_val", encodersPrefix: "_enc").
optional iterator index variable is now local (with let)

Removed:

doT.process (possibly will be added if there is an interest)
browser bundle (possibly will be added if there is a substantial interest)
dot-packer - can be added as a separate module to dot-template org
legacy doU engine
append: false option (only append: true now, that is faster and that was default anyway)
no HTML interpolation by default (see custom encoders above)
