+## [1.0.0] - 2019-04-24
+
+This release contains many breaking changes.
+
+It requires PHP `>= 5.6`, PHPCS `3.2.3+`, and WPCS `1.*`. It does not work with WPCS `2.*`.
+
+### Reorganisation and Renaming
+
+The sniffs in VIPCS have been reorganised into different categories, with new sniff names and new violation codes. The changes are detailed in the table below. If you reference any of the old violations in your custom ruleset (to change severity, type, or message), or with `// phpcs:ignore` or `// phpcs:disable`, you will need to updates these references to the new violation codes.

+- `WordPress-VIP-Go` ruleset test.
+- docs about ruleset tests.
+- XSD reference and ruleset validation.
+- `phpcodesniffer-composer-installer` plugin.
+- Copy `has_html_open_tag()` from WPCS.
+- Copy `AbstractVariableRestrictionsSniff` from WPCS.
+
+### Changed
+- Switch from PHPCS 2.* class names to PHPCS 3.* namespaced classes.
+- Refactor all sniffs to extend `VIPCS\Sniff`, which is an extension of `WordPress\Sniff`.
+- Tidied up:
+	- unused imports
+	- unused local variables
+	- unused parameters
+	- unused private field
+	- duplicate array keys
+	- redundant self-assignment
+	- assignment in conditions
+	- not returning void function calls
+	- undefined class fields
+	- strict comparisons
+	- missing scope keywords
+	- parentheses to clarify one specific conditional
+	- consolidate multiple `isset()` calls
+	- consolidate positive nested `if()`’s
+	- difference in case for function calls
+	- simplified return statements
+	- switched to `__DIR__`
+	- switched FQCN to import statements
+	- use static property
+	- use more performant `strpos()` instead of `substr()`
+	- split or remove `else` / `elseif` workflows for lower complexity and more comprehension
+	- misuse of `array_push()`
+	- misuse of `array_values()`
+	- misuse of `in_array()`
+	- useless `return`
+	- redundant `continue`
+	- comments that were naming parameters
+	- default assignments of `null` to class properties
+	- function parameters that match default arg values
+	- redundant parentheses
+- Ruleset Test improvements:
+	- Move mostly duplicate `PHPCS_Ruleset_Test` classes into new `RulesetTest` class.
+	- Refactor new class:
+		- Accept a ruleset name in the constructor
+		- Change public method from `run()` to `passes()`.
+		- Break out logic into smaller private methods to make the logic more self-documenting.
+		- Refactor variable names in some methods.
+		- Decode JSON into objects, not arrays
+		- Fix incorrect reference to local `$expected` to `$this->expected`. Somehow, this was still working regardless.
+		- Fix bug where it doesn't catch proper number of errors/warnings on a line basis due to order of operations of incrementating after assignment.
+		- Add further documentation.
+	- Change ruleset test class usage, including adding the name to the "tests passed!" message.
+	- Replaced WPCS whitelisting `// XSS OK` comments in this files with `// phpcs:ignore WordPress.Security.EscapeOutput.OutputNotEscaped` comments.
+	- Change naming of tests from "integration test" to "ruleset tests", to make it more intuitive exactly what these are (composer script, Travis, bin filename).
+- Improve `addError()` and `addWarning()` calls
+- Remove `Generic.NamingConventions.ConstructorName.OldStyle` from `WordPress-VIP-Go` ruleset
+- Travis: Restrict PHPUnit versions to match PHPCS
+- Travis: Use `7.4snapshot` instead of nightly, switch from Trusty to Xenial, remove `sudo: false`.
+- `EscapingVoidReturnFunctions`: Fix docs and improve logic
+- `AlwaysReturnSniff`: trigger errors instead of warnings, don't give violation for when callback args is passed by reference
+- Change `exec()` and `shell_exec()` to be flagged as Error.
+- Disallow long array syntax in VIPCS sniff code.
+- Remove a `WordPress.CodeAnalysis.AssignmentInCondition.FoundInWhileCondition` exclusion in the PHPCS config for VIPCS itself.
+- Update docs.
+
+### Fixed
+- Bumped PHPCompatibility `testVersion` to match PHP requirement.
+- Silence `Generic.PHP.DisallowShortOpenTag.EchoFound` for `WordPress-VIP-Go` ruleset: `<?=` is no longer reported.
+- Silence `WordPress.WP.AlternativeFunctions.file_system_read_fwrite` and `WordPress.WP.AlternativeFunctions.file_system_read_file_put_contents` since we have `WordPressVIPMinimum.Functions.RestrictedFunctions.file_ops_*`.
+- Silence Short Echo tags on `WordPress-VIP-Go`.
