+
+### Fixed
+
+## Release 2.19.0 (2019-03-02)
+
+IMPORTANT: This release reverts a change from 2.18.0
+
+In the previous release (2.18), we prematurely merged a partial change to the crypto functions that led to creating two sets of crypto functions (I blame @technosophos -- since that's me). This release rolls back that change, and does what was originally intended: It alters the existing crypto functions to use secure random.
+
+We debated whether this classifies as a change worthy of major revision, but given the proximity to the last release, we have decided that treating 2.18 as a faulty release is the correct course of action. We apologize for any inconvenience.
+
+### Changed
+
+- Fix substr panic 35fb796 (Alexey igrychev)
+- Remove extra period 1eb7729 (Matthew Lorimor)
+- Make random string functions use crypto by default 6ceff26 (Matthew Lorimor)
+- README edits/fixes/suggestions 08fe136 (Lauri Apple)
+
+
+## Release 2.18.0 (2019-02-12)
+
+### Added
+

+- Fix substr var names and comments d581f80 (Dean Coakley)
+- Fix substr documentation 2737203 (Dean Coakley)
+
+## Release 2.17.1 (2019-01-03)
+
+### Fixed

+# Slim-Sprig: Template functions for Go templates [![GoDoc](https://godoc.org/github.com/go-task/slim-sprig?status.svg)](https://godoc.org/github.com/go-task/slim-sprig) [![Go Report Card](https://goreportcard.com/badge/github.com/go-task/slim-sprig)](https://goreportcard.com/report/github.com/go-task/slim-sprig)
+
+Slim-Sprig is a fork of [Sprig](https://github.com/Masterminds/sprig), but with
+all functions that depend on external (non standard library) or crypto packages
+removed.
+The reason for this is to make this library more lightweight. Most of these
+functions (specially crypto ones) are not needed on most apps, but costs a lot
+in terms of binary size and compilation time.
+
+## Usage
+
+**Template developers**: Please use Slim-Sprig's [function documentation](https://go-task.github.io/slim-sprig/) for
+detailed instructions and code snippets for the >100 template functions available.
+
+**Go developers**: If you'd like to include Slim-Sprig as a library in your program,
+our API documentation is available [at GoDoc.org](http://godoc.org/github.com/go-task/slim-sprig).
+
+For standard usage, read on.
+
+### Load the Slim-Sprig library
+
+To load the Slim-Sprig `FuncMap`:
+
+```go
+
+import (
+  "html/template"
+
+  "github.com/go-task/slim-sprig"
+)
+
+// This example illustrates that the FuncMap *must* be set before the
+// templates themselves are loaded.
+tpl := template.Must(
+  template.New("base").Funcs(sprig.FuncMap()).ParseGlob("*.html")
+)
+```
+
+### Calling the functions inside of templates
+
+By convention, all functions are lowercase. This seems to follow the Go
+idiom for template functions (as opposed to template methods, which are
+TitleCase). For example, this:
+
+```
+{{ "hello!" | upper | repeat 5 }}
+```
+
+produces this:
+
+```
+HELLO!HELLO!HELLO!HELLO!HELLO!
+```
+
+## Principles Driving Our Function Selection
+
+We followed these principles to decide which functions to add and how to implement them:
+
+- Use template functions to build layout. The following
+  types of operations are within the domain of template functions:
+  - Formatting
+  - Layout
+  - Simple type conversions
+  - Utilities that assist in handling common formatting and layout needs (e.g. arithmetic)
+- Template functions should not return errors unless there is no way to print
+  a sensible value. For example, converting a string to an integer should not
+  produce an error if conversion fails. Instead, it should display a default
+  value.
+- Simple math is necessary for grid layouts, pagers, and so on. Complex math
+  (anything other than arithmetic) should be done outside of templates.
+- Template functions only deal with the data passed into them. They never retrieve
+  data from a source.
+- Finally, do not override core Go template functions.

+Package sprig provides template functions for Go.
+
+This package contains a number of utility functions for working with data
+inside of Go `html/template` and `text/template` files.
+
+To add these functions, use the `template.Funcs()` method:
+
+	t := templates.New("foo").Funcs(sprig.FuncMap())
+
+Note that you should add the function map before you parse any template files.
+
+	In several cases, Sprig reverses the order of arguments from the way they
+	appear in the standard library. This is to make it easier to pipe
+	arguments into functions.
+
+See http://masterminds.github.io/sprig/ for more detailed documentation on each of the available functions.

+# Ginkgo 2.0 is coming soon!
+
+An effort is underway to develop and deliver Ginkgo 2.0.  The work is happening in the [v2](https://github.com/onsi/ginkgo/tree/v2) branch and a changelog and migration guide is being maintained on that branch [here](https://github.com/onsi/ginkgo/blob/v2/docs/MIGRATING_TO_V2.md).  Issue [#711](https://github.com/onsi/ginkgo/issues/711) is the central place for discussion and links to the original [proposal doc](https://docs.google.com/document/d/1h28ZknXRsTLPNNiOjdHIO-F2toCzq4xoZDXbfYaBdoQ/edit#).
+
+As described in the [changelog](https://github.com/onsi/ginkgo/blob/v2/docs/MIGRATING_TO_V2.md) and [proposal](https://docs.google.com/document/d/1h28ZknXRsTLPNNiOjdHIO-F2toCzq4xoZDXbfYaBdoQ/edit#), Ginkgo 2.0 will clean up the Ginkgo codebase, deprecate and remove some v1 functionality, and add several new much-requested features.  To help users get ready for the migration, Ginkgo v1 has started emitting deprecation warnings for features that will no longer be supported with links to documentation for how to migrate away from these features.  If you have concerns or comments please chime in on [#711](https://github.com/onsi/ginkgo/issues/711).
+
+The current timeline for completion of 2.0 looks like:
+
+- Early April 2021: first public release of 2.0, deprecation warnings land in v1.
+- May 2021: first beta/rc of 2.0 with most new functionality in place.
+- June/July 2021: 2.0 ships and fully replaces the 1.x codebase on master.
+
 ## TLDR
 Ginkgo builds on Go's `testing` package, allowing expressive [Behavior-Driven Development](https://en.wikipedia.org/wiki/Behavior-driven_development) ("BDD") style tests.
 It is typically (and optionally) paired with the [Gomega](https://github.com/onsi/gomega) matcher library.
