+### [email protected] release
+
+`[email protected]` is [being released](https://github.com/brianc/node-postgres/pull/2117) which contains a handful of breaking changes.
+
+I will outline each breaking change here and try to give some historical context on them.  Most of them are small and subtle and likely wont impact you; __however__, there is one larger breaking change you will likely run into:
+
+___
+
+#### Support all `tls.connect` [options](https://nodejs.org/api/tls.html#tls_tls_connect_options_callback) being passed to the client/pool constructor under the `ssl` option.
+
+Previously we white listed the parameters passed here and did slight massaging of some of them.  The main __breaking__ change here is that now if you do this:
+
+```
+const client = new Client({ ssl: true })
+```
+
+<div class="alert alert-danger" style="margin-top: 20px">
+Now we will use the default ssl options to tls.connect which includes `rejectUnauthorized` being enabled.  This means your connection attempt may fail if you are using a self-signed cert.  To use the old behavior you should do this:
+</div>
+
+```
+const client = new Client({ ssl: { rejectUnauthorized: false }})
+```
+
+This makes pg a bit more secure "out of the box" while still enabling you to opt in to the old behavior.
+
+___
+
+The rest of the changes are relatively minor & you likely wont need to do anything, but good to be aware none the less!
+
+#### change default username
+
+If a user is not specified, available in the environment at `PGUSER`, or available at `pg.defaults`, we used to use the username of the process user as the name of the database. Now we will use the `user` property supplied to the client, if it exists. What this means is this:
+
+```
+new Client({
+  user: 'foo'
+})
+```
+
+`[email protected]` will default the database name to the _process_ user. `[email protected]` will use the `user` property supplied to the client. If you have not supplied `user` to the client, and it isn't available through any of its existing lookup mechanisms (environment variables, pg.defaults) then it will still use the process user for the database name.
+
+
+#### drop support for versions of node older than 8.0
+
+[email protected] has been out of LTS for quite some time now, and I've removed it from our test matrix.  `[email protected]` _may_ still work on older versions of node, but it isn't a goal of the project anymore.  [email protected] is actually no longer in the LTS support line, but pg will continue to test against and support 8.0 until there is a compelling reason to drop support for it.  Any security vulnerability issues which come up I will back-port fixes to the `[email protected]` line and do a release, but any other fixes or improvments will not be back ported.
+
+#### prevent password from being logged accidentally
+
+`[email protected]` makes the password field on the pool and client non-enumerable.  This means when you do `console.log(client)` you wont have your database password printed out unintenionally.  You can still do `console.log(client.password)` if you really want to see it!
+
+#### make `pg.native` non-enumerable
+
+You can use `pg.native.Client` to access the native client.  The first time you access the `pg.native` getter it imports the native bindings...which must be installed.  In some cases (such as webpacking the pg code for lambda deployment) the `.native` property would be traversed and trigger an import of the native bindings as a side-effect.  Making this property non-enumerable will fix this issue.  An easy fix, but its technically a breaking change in cases where people _are_ relying on this side effect for any reason.
+
+#### make `pg.Pool` an es6 class
+
+This makes extending `pg.Pool` possible.  Previously it was not a "proper" es6 class and `class MyPool extends pg.Pool` wouldn't work.
+
+#### make `Notice` messages _not_ an instance of a JavaScript error
+
+The code path for parsing `notice` and `error` messages from the postgres backend is the same.  Previously created a JavaScript `Error` instance for _both_ of these message types.  Now, only actual `errors` from the postgres backend will be an instance of an `Error`.  The _shape_ and _properties_ of the two messages did not change outside of this. 
+
+#### monorepo
+
+While not technically a breaking change for the module itself, I have begun the process of [consolidating](https://github.com/brianc/node-pg-query-stream) [separate](https://github.com/brianc/node-pg-cursor/) [repos](https://github.com/brianc/node-pg-pool) into the main [repo](https://github.com/brianc/node-postgres) and converted it into a monorepo managed by lerna.  This will help me stay on top of issues better (it was hard to bounce between 3-4 separate repos) and coordinate bug fixes and changes between dependant modules.
+
+Thanks for reading that!  pg tries to be super pedantic about not breaking backwards-compatibility in non semver major releases....even for seemingly small things.  If you ever notice a breaking change on a semver minor/patch release please stop by the [repo](https://github.com/brianc/node-postgres) and open an issue!
+
+_If you find `pg` valuable to you or your business please consider [supporting](http://github.com/sponsors/brianc) it's continued development!  Big performance improvements, typescript, better docs, query pipelining and more are all in the works!_
