Nette 3.0.0 alpha released!

Nette 3.0.0 alpha has just been released!

Nette is one of the very first frameworks that uses strict_types, scalar type hints and return type hints. Which is a fundamental step towards more robust applications.

Minimum required PHP version is 7.1 (7.0 for some packages).

This version is highly compatible with 2.4 and is intended for testing new type hints and strict_types features.

TODO: tool for automatic adding of the necessary type hints to your code.

Stages of development of individual packages

• Security, Robot-Loader, Php-Generator, Neon, Finder, Component-Model, Caching, Bootstrap: finished, just need to be tested
• Mail: all that remains is better API for SmtpMailer
• Utils: all that remains is support for immutable DateTime
• Database: resolve pull requests
• Application, Http: on roadmap are bigger internal changes to support middlewares (current stage is early alpha)
• Latte: on roadmap is the new API for macros with AST (current stage is early alpha)
• Form: on roadmap are improvements including automatic CSRF protection, dynamic forms, etc
• DI: on roadmap are improvements in Compiler extensions (priorities etc)
• Tester: all that remains is output handlers refactoring
• Tracy, Reflection, SafeStream, Tokenizer: new versions of these packages are not planned at the moment

BC breaks

Due to the new return type hints some method returns NULL instead of FALSE on failure:

• Strings::before(), after(), indexOf() and pos() return NULL instead of FALSE if the needle was not found
• Arrays::searchKey() returns NULL instead of FALSE when item is not found
• ContainerBuilder::getServiceName() returns NULL instead of FALSE
• Database\ResultSet: changed empty result return type of fetch() and fetchField() from FALSE to NULL
• UI\ComponentReflection::parseAnnotation() returns NULL instead of FALSE
• Latte\MacroTokens::fetchWord() returns NULL instead of FALSE on error
• PhpGenerator\Method: empty body is NULL instead of FALSE
• and Image::save() and send() throws ImageException on failure

Similary in Forms SubmitButton::setValidationScope() accepts ?array, so replace in your code FALSE with empty array []

Some classes & members are marked as final.

Deprecations

• first parameter $code is deprecated in UI\Component::redirect(), use redirectPermanent().
• UI\Component::getParam()
• ComponentModel\Component::__construct() parameter $parent is deprecated
• ComponentModel\Container::getComponents(): removed (unknown) child-first option
• Http: IRequest, IResponse, Url: parameters $default are deprecated

Database

• SqlPreprocessor: all scalars are always passed via binding (may cause BC break in Postgresql)
• there are changes in ISupplementalDriver (removed unused normalizeRow() and formatBool(), added formatDateInterval() and initialize()), in IStructure (added getPrimaryAutoincrementKey()) and IRowContainer (added fetchField())

DI

• removed deprecated support for inheritance ‘child < parent’

Http

• HttpExtension: uses interfaces Http\IRequest & Http\IResponse instead of Http\Request & Http\Response

PhpGenerator

• Helpers::formatArgs() checks for insufficient number of placeholders

RobotLoader

• $autoRebuild replaced with setAutoRefresh() (available since v2.4.2)
• setCacheStorage() replaced with setTempDirectory() (available since v2.4.2)
• RobotLoader is case sensitive

Security

• User::setExpiration() removed second argument $whenBrowserIsClosed and replaced with $flags (possible value IUserStorage::CLEAR_IDENTITY)

Utils

• Validators::assertField: first argument has type hint array
