OpenLP is a worship presentation program licensed under the GNU General Public License version 2. It includes the ability to search through lyrics for certain words, search for Bible verses in the Bible, display lyrics and Bible verses in a friendly way to the congregation and interact with popular presentation programs to provide users with an easy way to control a presentation (with LibreOffice Impress, OpenOffice.org Impress or Microsoft PowerPoint).[2] It also includes easy and instant switching between slides, customisable backgrounds, a song database, and video support.[3]
OpenLP was registered on SourceForge.net in February 2004 by Tim Ebenezer.[4] The software was first released on 28 February 2004[5] as version 0.1, and contained the bare basics of the application.[6] Version 0.4, released on 16 March 2004, was the first release with multi monitor support.[7]
On 18 March 2004, the 0.x line of OpenLP officially entered beta status[8] with the release of version 0.5.[9] By version 0.8, OpenLP had implemented most of the desired functionality.[10] Version 0.994 was the last release in the 0.x series of OpenLP, and was released on 11 October 2004.[11]
In mid-2004 Raoul Snyman joined the project, and suggested some architectural changes. With this in mind, Tim Ebenezer decided to drop the 0.x line and rewrite OpenLP from scratch, with a redefined user interface.[12] After various delays, OpenLP 1.0 beta 1 was finally released on 3 October 2005. At this stage, Tim also decided to rename OpenLP to openlp.org.
After the release of beta 1, Tim became too busy to work on openlp.org, and in early 2006 Raoul took over the project.[13] After an extensive beta and release candidate program, openlp.org version 1.0 was released on 1 February 2008.[14]
Initially, Raoul was going to work on a new version of openlp.org, version 1.2, in order to add fix up various faults in the implementation of the software,[15] while a new group of developers would work on OpenLP 2.0, a new cross-platform version of the software.[16] However, after looking at the progress of version 2.0, and consulting the other developers, Raoul decided to cease work on version 1.2.[17]
In the meantime, Derek Scotney joined the project, helping Raoul work on bugfixes for openlp.org 1.0. When Raoul moved on to help develop version 2.0, Derek continued to support version 1.0 with bug fixes. In October 2009 Derek released a new version of openlp.org that he had been working on, one that provided a backing track feature that his church needed.[18]
The OpenLP team released the first alpha version of OpenLP 2.0, OpenLP version 1.9.1, after about 18 months of development. This release was a preview release to show the community what the development team had been working on.[19] It was at this stage that the team renamed OpenLP back to its original name. Since then, there have been releases every 3 months.[20]
After over 2 years of development, the OpenLP team released their first beta of OpenLP 2.0 on 27 March 2011. With the release of this first beta, the OpenLP team announced that there would be no more bug fix releases for openlp.org 1.2, and that the beta release should be stable enough for most churches.[21]
Version 1.0 of openlp.org is no longer maintained. It was superseded by version 1.2.
Version 1.2.9 was the last stable release of the Delphi version of openlp.org. It was available for Microsoft Windows only. It is no longer supported.[22]
Version 2.0 was the first version written in Python and Qt4,[23] allowing it to run on most major operating systems including Linux, Mac OS X and Microsoft Windows.
Version 2.2 updated the code base to Python 3 and added support for video playback through VLC and presentation support via Libreoffice versions 4.0 and higher[24]
Version 2.4 upgraded the code base from PyQt4 to PyQt5, in order to use Qt5 and the newer capabilities of Qt5.[25]
Version 3.0 upgraded the code base and various new features.[26]

PyQt is a Python binding of the cross-platform GUI toolkit Qt, implemented as a Python plug-in. PyQt is free software developed by the British firm Riverbank Computing. It is available under similar terms to Qt versions older than 4.5; this means a variety of licenses including GNU General Public License (GPL) and commercial license, but not the GNU Lesser General Public License (LGPL). PyQt supports Microsoft Windows as well as various kinds of UNIX, including Linux and macOS. PyQt implements around 440 classes and over 6,000 functions and methods including: a substantial set of GUI widgets classes for accessing SQL databases (ODBC, MySQL, PostgreSQL, Oracle, SQLite) QScintilla, Scintilla-based rich text editor widget data aware widgets that are automatically populated from a database an XML parser SVG support classes for embedding ActiveX controls on Windows (only in commercial version) To automatically generate these bindings, Phil Thompson developed the tool SIP, which is also used in other projects.
This is a list of notable applications (apps) that run on the Android platform which meet guidelines for free software and open-source software.
This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses. Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source. For more information about the philosophical background for open-source software, see free software movement and Open Source Initiative. However, nearly all software meeting the Free Software Definition also meets the Open Source Definition and vice versa. A small fraction of the software that meets either definition is listed here. Some of the open-source applications are also the basis of commercial products, shown in the List of commercial open-source applications and services.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
