-# Release 1.2.0 (2016-02-01)
+# Changelog
+
+## Release 2.14.1 (2017-12-01)
+
+### Fixed
+
+- #60: Fix typo in function name documentation (thanks @neil-ca-moore)
+- #61: Removing line with {{ due to blocking github pages genertion
+- #64: Update the list functions to handle int, string, and other slices for compatibility
+
+## Release 2.14.0 (2017-10-06)
+
+This new version of Sprig adds a set of functions for generating and working with SSL certificates.
+
+- `genCA` generates an SSL Certificate Authority
+- `genSelfSignedCert` generates an SSL self-signed certificate
+- `genSignedCert` generates an SSL certificate and key based on a given CA
+
+## Release 2.13.0 (2017-09-18)
+
+This release adds new functions, including:
+
+- `regexMatch`, `regexFindAll`, `regexFind`, `regexReplaceAll`, `regexReplaceAllLiteral`, and `regexSplit` to work with regular expressions
+- `floor`, `ceil`, and `round` math functions
+- `toDate` converts a string to a date
+- `nindent` is just like `indent` but also prepends a new line
+- `ago` returns the time from `time.Now`
+
+### Added
+
+- #40: Added basic regex functionality (thanks @alanquillin)
+- #41: Added ceil floor and round functions (thanks @alanquillin)
+- #48: Added toDate function (thanks @andreynering)
+- #50: Added nindent function (thanks @binoculars)
+- #46: Added ago function (thanks @slayer)
+
+### Changed
+
+- #51: Updated godocs to include new string functions (thanks @curtisallen)
+- #49: Added ability to merge multiple dicts (thanks @binoculars)
+
+## Release 2.12.0 (2017-05-17)
+
+- `snakecase`, `camelcase`, and `shuffle` are three new string functions
+- `fail` allows you to bail out of a template render when conditions are not met
+
+## Release 2.11.0 (2017-05-02)
+
+- Added `toJson` and `toPrettyJson`
+- Added `merge`
+- Refactored documentation
+
+## Release 2.10.0 (2017-03-15)
+
+- Added `semver` and `semverCompare` for Semantic Versions
+- `list` replaces `tuple`
+- Fixed issue with `join`
+- Added `first`, `last`, `intial`, `rest`, `prepend`, `append`, `toString`, `toStrings`, `sortAlpha`, `reverse`, `coalesce`, `pluck`, `pick`, `compact`, `keys`, `omit`, `uniq`, `has`, `without`
+
+## Release 2.9.0 (2017-02-23)
+
+- Added `splitList` to split a list
+- Added crypto functions of `genPrivateKey` and `derivePassword`
+
+## Release 2.8.0 (2016-12-21)
+
+- Added access to several path functions (`base`, `dir`, `clean`, `ext`, and `abs`)
+- Added functions for _mutating_ dictionaries (`set`, `unset`, `hasKey`)
+
+## Release 2.7.0 (2016-12-01)
+
+- Added `sha256sum` to generate a hash of an input
+- Added functions to convert a numeric or string to `int`, `int64`, `float64`
+
+## Release 2.6.0 (2016-10-03)
+
+- Added a `uuidv4` template function for generating UUIDs inside of a template.
+
+## Release 2.5.0 (2016-08-19)
+
+- New `trimSuffix`, `trimPrefix`, `hasSuffix`, and `hasPrefix` functions
+- New aliases have been added for a few functions that didn't follow the naming conventions (`trimAll` and `abbrevBoth`)
+- `trimall` and `abbrevboth` (notice the case) are deprecated and will be removed in 3.0.0
+
+## Release 2.4.0 (2016-08-16)
+
+- Adds two functions: `until` and `untilStep`
+
+## Release 2.3.0 (2016-06-21)
+
+- cat: Concatenate strings with whitespace separators.
+- replace: Replace parts of a string: `replace " " "-" "Me First"` renders "Me-First"
+- plural: Format plurals: `len "foo" | plural "one foo" "many foos"` renders "many foos"
+- indent: Indent blocks of text in a way that is sensitive to "\n" characters.
+
+## Release 2.2.0 (2016-04-21)
+
+- Added a `genPrivateKey` function (Thanks @bacongobbler)
+
+## Release 2.1.0 (2016-03-30)
+
+- `default` now prints the default value when it does not receive a value down the pipeline. It is much safer now to do `{{.Foo | default "bar"}}`.
+- Added accessors for "hermetic" functions. These return only functions that, when given the same input, produce the same output.
+
+## Release 2.0.0 (2016-03-29)
+
+Because we switched from `int` to `int64` as the return value for all integer math functions, the library's major version number has been incremented.
+
+- `min` complements `max` (formerly `biggest`)
+- `empty` indicates that a value is the empty value for its type
+- `tuple` creates a tuple inside of a template: `{{$t := tuple "a", "b" "c"}}`
+- `dict` creates a dictionary inside of a template `{{$d := dict "key1" "val1" "key2" "val2"}}` 
+- Date formatters have been added for HTML dates (as used in `date` input fields)
+- Integer math functions can convert from a number of types, including `string` (via `strconv.ParseInt`).
+
+## Release 1.2.0 (2016-02-01)
 
 - Added quote and squote
 - Added b32enc and b32dec
