-## [1.10.2](https://github.com/istanbuljs/istanbuljs/compare/istanbul-lib-instrument@1.9.2...istanbul-lib-instrument@1.10.2) (2018-09-05)
-
-
-### Bug Fixes
-
-* Tweak package.json files for republish as latest 1.x. ([#217](https://github.com/istanbuljs/istanbuljs/issues/217)) ([420481d](https://github.com/istanbuljs/istanbuljs/commit/420481d)), closes [#216](https://github.com/istanbuljs/istanbuljs/issues/216)
-
-
-### BREAKING CHANGES
-
-* leaked into 1.x modules but it was thought they were
-never released to latest.  Apparently releasing 2.x to latest makes
-those unwanted versions of 1.x available.
-
-This patch sets all modules to the latest 1.x version (4.x for
-test-exclude).  This will allow a new release to be made to revert
-release of the breaking changes.
-
-Stop upgrading npm to latest for testing as it's not compatible with
-node 4.x.

-istanbul-lib-instrument
------------------------
-
-[![Build Status](https://travis-ci.org/istanbuljs/istanbul-lib-instrument.svg?branch=master)](https://travis-ci.org/istanbuljs/istanbul-lib-instrument)
-
-Istanbul instrumenter library.
-
-Version 1.1.x now implements instrumentation using `Babel`. The implementation is inspired
-by prior art by @dtinth as demonstrated in the `__coverage__` babel plugin.
-
-It provides 2 "modes" of instrumentation.
-
-* The old API that is mostly unchanged (except for incompatibilities noted) and
-  performs the instrumentation using babel as a library.
-
-* A `programVisitor` function for the Babel AST that can be used by a Babel plugin
-  to emit instrumentation for ES6 code directly without any source map
-  processing. This is the preferred path for babel users. The Babel plugin is
-  called `babel-plugin-istanbul`.
-
-Incompatibilities and changes to instrumentation behavior can be found in
-[v0-changes.md](v0-changes.md).

- * programVisitor is a `babel` adaptor for instrumentation.

- * These functions do not make assumptions about the state set by Babel and thus
- * can be used in a context other than a Babel plugin.
- *
- * The exit function returns an object that currently has the following keys:
- *
- * `fileCoverage` - the file coverage object created for the source file.
- * `sourceMappingURL` - any source mapping URL found when processing the file.
- *
- * @param {Object} types - an instance of babel-types
- * @param {string} sourceFilePath - the path to source file
- * @param {Object} opts - additional options
- * @param {string} [opts.coverageVariable=__coverage__] the global coverage variable name.
- * @param {object} [opts.inputSourceMap=undefined] the input source map, that maps the uninstrumented code back to the
