+The Ubuntu Font Family is very long-term endeavour, and the first time
+that a professionally-designed font has been funded specifically with
+the intent of being an on-going community expanded project:
+
+  http://font.ubuntu.com/
+
+Development of the Ubuntu Font Family is undertaken on Launchpad:
+
+  http://launchpad.net/ubuntu-font-family/
+
+and this is where milestones, bug management and releases are handled.
+
+Contributions are welcomed.  Your work will be used on millions of
+computers every single day!  Following the initial bootstrapping of
+Latin, Cyrillic, Greek, Arabic and Hebrew expansion will be undertaken
+by font designers from the font design and Ubuntu communities.
+
+To ensure that the Ubuntu Font Family can be re-licensed to future
+widely-used libre font licences, copyright assignment is being required:

+
+
+Overview
+
+The new Ubuntu Font Family was started to enable the personality of
+Ubuntu to be seen and felt in every menu, button and dialog.
+The typeface is sans-serif, uses OpenType features and is manually
+hinted for clarity on desktop and mobile computing screens.
+
+The scope of the Ubuntu Font Family includes all the languages used by
+the various Ubuntu users around the world in tune with Ubuntu's
+philosophy which states that every user should be able to use their
+software in the language of their choice. So the Ubuntu Font Family
+project will be extended to cover many more written languages.
+
+
+History
+
+The Ubuntu Font Family has been creating during 2010 and 2011.  As of
+September 2011 coverage is provided for Latin, Cyrillic and Greek across
+Regular, Italic, Bold and Bold-Italic.  Further work was uptaken during
+2015.

+ChangeLog
+
+2015-08-21 (Paul Sladen) Ubuntu Font Family version 0.83
+
+  Note: This release was created by binary patching from the v0.80
+  release using the scripts in 'sources/patch-0.80-0.83/' to rebuild
+  the necessary tables. The release selectively updates only those
+  proportional .ttf font files exhibiting the bug below bug number;
+  the Ubuntu Mono monospace font files remain unchanged, being the
+  original version 0.80 ones.

+                        Ubuntu Font Family Licensing FAQ
+
+  Stylistic Foundations
+
+   The Ubuntu Font Family is the first time that a libre typeface has been
+   designed professionally and explicitly with the intent of developing a
+   public and long-term community-based development process.
+
+   When developing an open project, it is generally necessary to have firm
+   foundations: a font needs to maintain harmony within itself even across
+   many type designers and writing systems. For the [1]Ubuntu Font Family,
+   the process has been guided with the type foundry Dalton Maag setting
+   the project up with firm stylistic foundation covering several
+   left-to-right scripts: Latin, Greek and Cyrillic; and right-to-left
+   scripts: Arabic and Hebrew (due in 2011).
+
+   With this starting point the community will, under the supervision of
+   [2]Canonical and [3]Dalton Maag, be able to build on the existing font
+   sources to expand their character coverage. Ultimately everybody will
+   be able to use the Ubuntu Font Family in their own written languages
+   across the whole of Unicode (and this will take some time!).
+
+  Licensing
+
+   The licence chosen by any free software project is one of the
+   foundational decisions that sets out how derivatives and contributions
+   can occur, and in turn what kind of community will form around the
+   project.
+
+   Using a licence that is compatible with other popular licences is a
+   powerful constraint because of the [4]network effects: the freedom to
+   share improvements between projects allows free software to reach
+   high-quality over time. Licence-proliferation leads to many
+   incompatible licences, undermining the network effect, the freedom to
+   share and ultimately making the libre movement that Ubuntu is a part of
+   less effective. For all kinds of software, writing a new licence is not
+   to be taken lightly and is a choice that needs to be thoroughly
+   justified if this path is taken.
+
+   Today it is not clear to Canonical what the best licence for a font
+   project like the Ubuntu Font Family is: one that starts life designed
+   by professionals and continues with the full range of community
+   development, from highly commercial work in new directions to curious
+   beginners' experimental contributions. The fast and steady pace of the
+   Ubuntu release cycle means that an interim libre licence has been
+   necessary to enable the consideration of the font family as part of
+   Ubuntu 10.10 operating system release.
+
+   Before taking any decision on licensing, Canonical as sponsor and
+   backer of the project has reviewed the many existing licenses used for
+   libre/open fonts and engaged the stewards of the most popular licenses
+   in detailed discussions. The current interim licence is the first step
+   in progressing the state-of-the-art in licensing for libre/open font
+   development.
+
+   The public discussion must now involve everyone in the (comparatively
+   new) area of the libre/open font community; including font users,
+   software freedom advocates, open source supporters and existing libre
+   font developers. Most importantly, the minds and wishes of professional
+   type designers considering entering the free software business
+   community must be taken on board.
+
+   Conversations and discussion has taken place, privately, with
+   individuals from the following groups (generally speaking personally on
+   behalf of themselves, rather than their affiliations):
+     * [5]SIL International
+     * [6]Open Font Library
+     * [7]Software Freedom Law Center
+     * [8]Google Font API
+
+    Document embedding
+
+   One issue highlighted early on in the survey of existing font licences
+   is that of document embedding. Almost all font licences, both free and
+   unfree, permit embedding a font into a document to a certain degree.
+   Embedding a font with other works that make up a document creates a
+   "combined work" and copyleft would normally require the whole document
+   to be distributed under the terms of the font licence. As beautiful as
+   the font might be, such a licence makes a font too restrictive for
+   useful general purpose digital publishing.
+
+   The situation is not entirely unique to fonts and is encountered also
+   with tools such as GNU Bison: a vanilla GNU GPL licence would require
+   anything generated with Bison to be made available under the terms of
+   the GPL as well. To avoid this, Bison is [9]published with an
+   additional permission to the GPL which allows the output of Bison to be
+   made available under any licence.
+
+   The conflict between licensing of fonts and licensing of documents, is
+   addressed in two popular libre font licences, the SIL OFL and GNU GPL:
+     * [10]SIL Open Font Licence: When OFL fonts are embedded in a
+       document, the OFL's terms do not apply to that document. (See
+       [11]OFL-FAQ for details.
+     * [12]GPL Font Exception: The situation is resolved by granting an
+       additional permission to allow documents to not be covered by the
+       GPL. (The exception is being reviewed).
+
+   The Ubuntu Font Family must also resolve this conflict, ensuring that
+   if the font is embedded and then extracted it is once again clearly
+   under the terms of its libre licence.
+
+    Long-term licensing
+
+   Those individuals involved, especially from Ubuntu and Canonical, are
+   interested in finding a long-term libre licence that finds broad favour
+   across the whole libre/open font community. The deliberation during the
+   past months has been on how to licence the Ubuntu Font Family in the
+   short-term, while knowingly encouraging everyone to pursue a long-term
+   goal.
+     * [13]Copyright assignment will be required so that the Ubuntu Font
+       Family's licensing can be progressively expanded to one (or more)
+       licences, as best practice continues to evolve within the
+       libre/open font community.
+     * Canonical will support and fund legal work on libre font licensing.
+       It is recognised that the cost and time commitments required are
+       likely to be significant. We invite other capable parties to join
+       in supporting this activity.
+
+   The GPL version 3 (GPLv3) will be used for Ubuntu Font Family build
+   scripts and the CC-BY-SA for associated documentation and non-font
+   content: all items which do not end up embedded in general works and
+   documents.
+
+Ubuntu Font Licence
+
+   For the short-term only, the initial licence is the [14]Ubuntu Font
+   License (UFL). This is loosely inspired from the work on the SIL
+   OFL 1.1, and seeks to clarify the issues that arose during discussions
+   and legal review, from the perspective of the backers, Canonical Ltd.
+   Those already using established licensing models such as the GPL, OFL
+   or Creative Commons licensing should have no worries about continuing
+   to use them. The Ubuntu Font Licence (UFL) and the SIL Open Font
+   Licence (SIL OFL) are not identical and should not be confused with
+   each other. Please read the terms precisely. The UFL is only intended
+   as an interim license, and the overriding aim is to support the
+   creation of a more suitable and generic libre font licence. As soon as
+   such a licence is developed, the Ubuntu Font Family will migrate to
+   it—made possible by copyright assignment in the interium. Between the
+   OFL 1.1, and the UFL 1.0, the following changes are made to produce the
+   Ubuntu Font Licence:
+     * Clarification:
+
+    1. Document embedding (see [15]embedding section above).
+    2. Apply at point of distribution, instead of receipt
+    3. Author vs. copyright holder disambiguation (type designers are
+       authors, with the copyright holder normally being the funder)
+    4. Define "Propagate" (for internationalisation, similar to the GPLv3)
+    5. Define "Substantially Changed"
+    6. Trademarks are explicitly not transferred
+    7. Refine renaming requirement
+
+     Streamlining:
+    8. Remove "not to be sold separately" clause
+    9. Remove "Reserved Font Name(s)" declaration
+
+   A visual demonstration of how these points were implemented can be
+   found in the accompanying coloured diff between SIL OFL 1.1 and the
+   Ubuntu Font Licence 1.0: [16]ofl-1.1-ufl-1.0.diff.html

+-------------------------------
+UBUNTU FONT LICENCE Version 1.0
+-------------------------------
+
+PREAMBLE
+This licence allows the licensed fonts to be used, studied, modified and
+redistributed freely. The fonts, including any derivative works, can be
+bundled, embedded, and redistributed provided the terms of this licence
+are met. The fonts and derivatives, however, cannot be released under
+any other licence. The requirement for fonts to remain under this
+licence does not require any document created using the fonts or their
+derivatives to be published under this licence, as long as the primary
+purpose of the document is not to be a vehicle for the distribution of
+the fonts.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this licence and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Original Version" refers to the collection of Font Software components
+as received under this licence.
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to
+a new environment.
+
+"Copyright Holder(s)" refers to all individuals and companies who have a
+copyright ownership of the Font Software.
+
+"Substantially Changed" refers to Modified Versions which can be easily
+identified as dissimilar to the Font Software by users of the Font
+Software comparing the Original Version with the Modified Version.
+
+To "Propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification and with or without charging
+a redistribution fee), making available to the public, and in some
+countries other activities as well.
+
+PERMISSION & CONDITIONS
+This licence does not grant any rights under trademark law and all such
+rights are reserved.
+
+Permission is hereby granted, free of charge, to any person obtaining a
+copy of the Font Software, to propagate the Font Software, subject to
+the below conditions:
+
+1) Each copy of the Font Software must contain the above copyright
+notice and this licence. These can be included either as stand-alone
+text files, human-readable headers or in the appropriate machine-
+readable metadata fields within text or binary files as long as those
+fields can be easily viewed by the user.
+
+2) The font name complies with the following:
+(a) The Original Version must retain its name, unmodified.
+(b) Modified Versions which are Substantially Changed must be renamed to
+avoid use of the name of the Original Version or similar names entirely.
+(c) Modified Versions which are not Substantially Changed must be
+renamed to both (i) retain the name of the Original Version and (ii) add
+additional naming elements to distinguish the Modified Version from the
+Original Version. The name of such Modified Versions must be the name of
+the Original Version, with "derivative X" where X represents the name of

+  Ubuntu Font Family
+ ======================
+
+The Ubuntu Font Family are a set of matching new libre/open fonts in
+development during 2010--2011.  And with further expansion work and
+bug fixing during 2015.  The development is being funded by
+Canonical Ltd on behalf the wider Free Software community and the
+Ubuntu project.  The technical font design work and implementation is
+being undertaken by Dalton Maag.
+
+Both the final font Truetype/OpenType files and the design files used
+to produce the font family are distributed under an open licence and
+you are expressly encouraged to experiment, modify, share and improve.

+Ubuntu Font Family source code
+
+  *  *.vfb design files are used with FontLab Studio 5.
+  *  VTT/*.ttf files are inputs to MS Visual TrueType (Hinting)
+  *  CacheTT/*.cfg file is input to MS CacheTT
+
+Free-as-in-beer programs, to process these files can be found at:
+
+  http://www.microsoft.com/typography/tools/vtt.aspx
+  http://www.microsoft.com/typography/tools/tools.aspx
+
+Commercial programs, with a free-as-in-beer limited trial version:
+
+  http://www.fontlab.com/font-editor/fontlab-studio/
+
+The build process used by Dalton Maag is as follows.  There are no
+multiple-masters, any interpolation is done by the designers from the
+base font.  Per-font there are currently a total of two source files:
+
+   1. FL: Make adjustments in FontLab
+   2. FL: Note list of changed glyphs somewhere (eg. a sheet of paper)
+   3. FL: Export as W.ttf
+   4. VTT: Load W.ttf into VTT
+   5. VTT: Partially import X.ttf (including VTT private "source"
+      table), manually deselecting any changed glyphs noted earlier
+   6. VTT: Make adjustments in VTT
+   7. VTT: Save as X.ttf (including VTT private "source" tables)
+   8. VTT: Export as Y.ttf (without VTT private "source" tables)
+   9. CacheTT: Process Y.ttf + configuration file with MS CacheTT
+      ("optimisation stage")
+  10. CacheTT: Distribute optimised Z.ttf as end-user file
+
+This 'Z.ttf' is the version that is then shipped, there is no merging
+(other than selective import of glyphs metadata from previous version
+in VTT), and no use of VOLT in the current pipeline, although VOLT
+will be used for Arabic.  To reproduce the output .ttfs, the following
+are required:
+
+   1. one-off .vfb per font (currently four)
+   2. one-off .ttf per font (containing VTT "source" tables)
+   4. one-off CacheTT .cfg configuration file (across all fonts)
+   3. one-off .ttf per font (final output)
