Change Log

All notable changes to this project will be documented in this file.

This project adheres to Semantic Versioning.

Changes are grouped by added, fixed or changed feature.

[3.0.2] - 2019-08-25

• Set minimum PHP requirement to 7.2.19

[3.0.1] - 2019-04-19

• More refactoring and fixes to Ui\Xml.

[3.0.0] - 2019-04-13

• Bumped version requirement to PHP 7.2.
• Db package is now separated to its own component, Libvaloa-db. Libvaloa will only concentrate on XSL UI and related utilities.
• Remove I18n package completely. There are better translation libs out there, so it doesn't really bring any value to Libvaloa.
• Move all debug classes under Debug package. Effectively: Debug -> Debug\Debug, Debugtimer -> Debug\Debugtimer, Xml\DomDebug -> Debug\DomDebug.
• Deprecate and remove Xml\Xml and fully concentrate on maintaining Xml\Conversion. Conversion is little more resource heavy than Xml\Xml, but basically Xml\Xml is redurant and doesn't do anything Conversion doesn't do.
• Add return type declarations where acceptable.

[2.0.0] - 2018-06-04

Added

• Rename Db\Object as Db\Item, this is necessary for PHP 7.2 compatibility (Object is now reserved word).

[1.3.0] - 2018-03-22

Added

• Set and bind in Db\ResultSet now allow PDO type constants to be passed as a parameter.

[1.2.3] - 2018-03-21

Fixed

[1.2.2] - 2018-03-21

Fixed

• Gettext now returns original string if translation is not found.

[1.2.1] - 2018-03-13

Fixed

Added

• Gettext translation support, \I18n\Translate\Gettext.

• Xml/Xml now uses Xml/Conversion when including view data with addObject.

• Updated PHP requirement to 5.6 to simplify maintainance.
• Memory requirements are slightly higher after Xml/Conversion migration.
