We have just released new versions of
and , the libraries that take all the heavy lifting for color space conversion and image processing in GIMP. Both releases are considered a pre-requisite for doing a first 2.9 (development series) GIMP release.
The babl library got floating point conversions optimized. Additionally, HSV and HSL color models were added, CIE LAB conversions were fixed.
Most exciting improvements, however, are in the new GEGL release. A total of 71 new image processing operations were added: mostly these are ports of existing GIMP filters. Some of the existing operations were improved, and some got OpenCL versions.
Another focus of this release was performance: OpenCL support is now enabled by default when detected, there's experimental multithreading support (use GEGL_THREADS=&number of threads& environment variable) and experimental mipmap rendering (use GEGL_MIPMAP_RENDERING=true environment variable). There's also a new default tile backend that writes to disk in a separate thread.
project contributed several major improvements: support for using URIs in image loaders and the loading of , created with imgflo's online graph editor.
GEGL's website now features a

This release of GEGL was brought to you through contributions from 92 people. Respective source code downloads are available on gimp.org: , .
There is still a lot of work to be done. If you are interested to contribute ports of GIMP filters to GEGL or entirely new GEGL operations, please visit

This is the GIMP project's official statement on
in regard to "abandoned" projects on their service.
It is archived in the .
We are fully aware that since their launch in 1999, SourceForge had been providing a valuable service to the Free Software community and that this service may still be relevant to some Free and Open Source Software projects today.
The GIMP project did benefit from this service: SourceForge was the place to download the Windows installer for GIMP for many years and we appreciate it as an important part of GIMP history.
When it comes to distributing GIMP, our goal is to make it as easy as possible for users to install GIMP.
We do not want our users having to dodge any "offers" or to worry about possibly installing malware in the process.
With our shared history, it was painful to watch the invasion of the big green "Download" button ads appearing on the SourceForge site.
Our decision to move the Windows installers away from SourceForge in 2013 was a direct result of how its service degraded in this respect.
The situation became worse recently when SourceForge started to wrap its downloader/installer around the GIMP project binaries. That SourceForge installer put other software apart from GIMP on our users' systems. This was done without our knowledge and permission, and we would never have permitted it. It was done in spite of the following :
we want to reassure you that we will NEVER bundle offers with any project without the developers consent. (emphasis in original)
To us, this firmly places SourceForge among the dodgy crowd of download sites.
SourceForge are abusing the trust that we and our users had put into their service in the past.
We don't believe that this is a fixable situation.
Even if they promise to adhere to the set of guidelines outlined below, these promises are likely to become worthless with any upcoming management change at SourceForge.
However, if SourceForge's current management are willing to collaborate with us on these matters, then there might be a reduction in the damage and feeling of betrayal among the Free and Open Source Software communities.
An acceptable approach would be to provide a method for *any* project to cease hosting at any SourceForge site if desired, including the ability to:
completely remove the project and URLs permanently, and not allow any other projects to take its place
remove any hosted files from the service, and not maintain mirrors serving installers or files differing from those provided by the project or wrap those in any way
provide permanent HTTP redirects (301) to any other location as desired by the project
This is not unreasonable to expect from a service that purports to support the free software community.
Some of you might remember that in November 2013,
(SF) as the primary download site for the GIMP installers for Windows platforms and moved the files to our own download server,
The tons of links on the web pointing to the former site made keeping the installers there as well a necessity, though, and since SF claimed that our outrage over their "installer with benefits" was based on a , this seemed to be a low-risk approach.
However we are
that people who get there by chance receive small installers that include additional software. And it's no clicks on those 'big green download arrow' ads this time, we've tried ourselves. SF has not responded to our inquiry yet, and we found that the maintainer of the GIMP for Windows installers is locked out of that SF project now.
And now SF is launching an attempt at .

During Libre Graphics Meeting 2015 last week in Toronto our very own Jehan Pagès announced a new open animated movie project, . It's a road movie with a marmot as protagonist.
The team will be using just free/libre applications for the production: GIMP, , , and a few others. Jehan will also resume his work on animation features in GIMP, extend OpenRaster file format to support animation, and improve Blender's non-linear video editor as much as he can.

We noticed that gimpguru.org, once the host of GIMP tutorials (some of which are also present in our ) has been abandoned by its original owner and is redirecting visitors to some very suspicious downloads - don't go there.
We have removed all links pointing there from the tutorials (please do tell if we missed one), and caution everyone to only consider links on our own
and the sites linked from there.
Special announcement for domain owners: if you own a domain with *gimp* in its name and host a forum or something else, and don't feel like you want to continue to do so or renew it some day, please
- we'd rather take it over ourselves and have it point to www.gimp.org than see it being abused like that.
In 2014, we spent most of the time on improving GIMP's usability and finalizing the GEGL port of GIMP to lay the foundation for various advanced features in demand by professionals. Some of the 2014 highlights are:
Redesigned Blend tool, now you can tweak end points before applyi
Improved foreground selection tool that handles fi
Finer control ov
Up to 64bit per colo
Improved file formats support, including 32bit TIFF loading/saving.

When software is popular, then there are elements out there who seek to profit from it by less ethical means. Installer packages with added spyware, adware or even malware are apparently part of the (Windows) user experience these days.
GIMP is being attacked in that manner as well, In order to keep safe,

One victim of this is GIMPshop - started as a fork of GIMP to add UI terms that are more familiar to users of Adobe Photoshop, it is nowadays used to load third-party software onto the unwary user's system. Thankfully, the original author is not to blame, as this operation is run by someone else.
The newly released issue #6 of GIMP Magazine features a "Using GIMP for portrait and fashion photography" master class by Aaron Tyree who uses GIMP professionally, and a gallery of other artworks and photos made or processed with GIMP.

The Grand Design is a
written by
and published by
in 2010. It argues that invoking God is not necessary to explain the origins of the universe, and that the
is a consequence of the laws of
alone. In response to criticism, H "One can't prove that God doesn't exist, but science makes God unnecessary." When pressed on his own religious views by the
documentary , he has clarified that he does not believe in a personal God.
The authors of the book point out that a
(a theory, based on an early model of the , proposed by
and other physicists) may not exist. The book examines the history of scientific knowledge about the universe and explains 11 dimension , a theory many modern physicists support.
Published in the United States on September 7, 2010, the book became the number one
just a few days after publication. It was published in the United Kingdom on September 9, 2010, and became the number two bestseller on
on the same day. It topped the list of adult
books of the
in Sept-Oct 2010.
The book examines the history of scientific knowledge about the universe. It starts with the
, who claimed that nature works by laws, and not by the will of the gods. It later presents the work of , who advocated the concept that the Earth is not located in the center of the universe.
The authors then describe the theory of
using, as an example, the probable movement of an
around a room. The presentation has been described as easy to understand by some reviewers, but also as sometimes "impenetrable," by others.
The central claim of the book is that the theory of
together help us understand how universes could have formed out of nothing.
The authors write:
Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.
—Stephen Hawking and Leonard Mlodinow, The Grand Design, 2010
The authors explain, in a manner consistent with , that as the Earth is only one of several
in our , and as our
is only one of many galaxies, the same may apply to our universe itself: that is, our universe may be one of a huge number of universes.
The book concludes with the statement that only some universes of the multiple universes (or ) support life forms. We, of course, are located in one of those universes. The laws of nature that are required for life forms to exist appear in some universes by pure chance, Hawking and Mlodinow explain (see ).
and advocate for
welcomed Hawking's position and said that " kicked God out of biology but physics remained more uncertain. Hawking is now administering the ."
Theoretical physicist , writing in , described the book as speculative but ambitious: "The important lesson of The Grand Design is not so much the particular theory being advocated but the sense that science may be able to answer the deep 'Why?' questions that are part of fundamental human curiosity."
Dr. , in his article "Our Spontaneous Universe", wrote that "there are remarkable, testable arguments that provide firmer
of the possibility that our universe arose from nothing. ... If our universe arose spontaneously from nothing at all, one might predict that its total energy should be zero. And when we measure the total energy of the universe, which could have been anything, the answer turns out to be the only one consistent with this possibility. Coincidence? Maybe. But data like this coming in from our revolutionary new tools promise to turn much of what is now
into physics. Whether God survives is anyone's guess."
, a professor of physics at , said in his
review: "I've waited a long time for this book. It gets into the deepest questions of modern
without a single equation. The reader will be able to get through it without bogging down in a lot of technical detail and will, I hope, have his or her appetite whetted for books with a deeper technical content. And who knows? Maybe in the end the whole
idea will actually turn out to be right!" Canada Press journalist Carl Hartman said: "Cosmologists, the people who study the entire cosmos, will want to read British physicist and mathematician Stephen Hawking's new book. The Grand Design may sharpen appetites for answers to questions like 'Why is there something rather than nothing?' and 'Why do we exist?' – questions that have troubled thinking people at least as far back as the ancient Greeks."
Writing in the ,
praised the authors: "their arguments do indeed bring us closer to seeing our world, universe and multiverse in terms that a previous generation might easily have dismissed as supernatural. This succinct, easily digested book could perhaps do with fewer dry, academic groaners, but Hawking and Mlodinow pack in a wealth of ideas and leave us with a clearer understanding of modern physics in all its invigorating complexity."
German daily

physicist and novelist

from the 18th century to , and takes Hawking's conclusion on God's existence as a very good joke which he obviously welcomes very much.
doubts that adequate understandings can come from this approach, and points out that "unlike quantum mechanics,
enjoys no observational support whatsoever".
in Science suggests that "Some humbleness would be welcome here...A century or two hence...I expect that M-theory will seem as na?ve to cosmologists of the future as we now find 's cosmology of the ".
in "The Big Bang Creation: God or the Laws of Nature" explains that "The Grand Design breaks the news, bitter to some, that … to create a universe from absolute nothing God is not necessary. All that is needed are the laws of nature. … [That is,] there can have been a big bang creation without the help of God, provided the laws of nature pre-date the universe. Our concept of time begins with the creation of the universe. Therefore if the laws of nature created the universe, these laws must have e that is the laws of nature would be outside of time. What we have then is totally non-physical laws, outside of time, creating a universe. Now that description might sound somewhat familiar. Very much like the biblical concept of God: not physical, outside of time, able to create a universe."
was critical of the book, saying: "The real news about The Grand Design is how disappointingly tinny and inelegant it is. The spare and earnest voice that Mr. Hawking employed with such appeal in
has been replaced here by one that is alternately condescending, as if he were
explaining rain clouds to toddlers, and impenetrable."
, in the , was not convinced by the theory promoted in the book: "M-theory ... is far from complete. But that doesn't stop the authors from asserting that it explains the mysteries of existence ... In the absence of theory, though, this is nothing more than a hunch doomed – until we start watching universes come into being – to remain untested. The lesson isn't that we face a dilemma between God and the , but that we shouldn't go off the rails at the first sign of coincidences.
wrote: "The multiverse comes with a lot of baggage, such as an overarching space and time to host all those bangs, a universe-generating mechanism to trigger them, physical fields to populate the universes with material stuff, and a selection of forces to make things happen. Cosmologists embrace these features by envisaging sweeping "meta-laws" that pervade the multiverse and spawn specific bylaws on a universe-by-universe basis. The meta-laws themselves remain unexplained – eternal, immutable transcendent entities that just happen to exist and must simply be accepted as given. In that respect the meta-laws have a similar status to an unexplained transcendent god." Davies concludes "there is no compelling need for a supernatural being or prime mover to start the universe off. But when it comes to the laws that explain the big bang, we are in murkier waters."
Dr. , in his article "Hawking And God: An Intimate Relationship", stated that "contemplating a final theory is inconsistent with the very essence of physics, an empirical science based on the gradual collection of data. Because we don’t have instruments capable of measuring all of Nature, we cannot ever be certain that we have a final theory. There’ll always be room for surprises, as the history of physics has shown again and again. In fact, I find it quite pretentious to imagine that we humans can achieve such a thing. ... Maybe Hawking should leave God alone."
Physicist , of , has criticized the book: "One thing that is sure to generate sales for a book of this kind is to somehow drag in religion. The book's rather conventional claim that "God is unnecessary" for explaining physics and early universe cosmology has provided a lot of publicity for the book. I'm in favor of naturalism and leaving God out of physics as much as the next person, but if you're the sort who wants to go to battle in the , why you would choose to take up such a dubious weapon as M-theory mystifies me."
is not sympathetic to the book: "M-theory, theorists now realize, comes in an almost infinite number of versions, which "predict" an almost infinite number of possible universes. Critics call this the " problem," a reference to the refrain of the old
folk song: "You can get anything you want at Alice's Restaurant." Of course, a theory that predicts everything really doesn't predict anything... The
has always struck me as so dumb that I can't understand why anyone takes it seriously. It's cosmology's version of . ... The physicist , with whom I worked at Scientific American in the 1990s, liked to say that the anthropic principle in any form is completely ridiculous and hence should be called CRAP. ... Hawking is telling us that unconfirmable M-theory plus the anthropic tautology represents the end of that quest. If we believe him, the joke’s on us."
is also critical of the book: Hawking and Mlodinow "...say that these surprising ideas have passed every experimental test to which they have been put, but that is misleading in a way that is unfortunately typical of the authors. It is the bare bones of quantum mechanics that have proved to be consistent with what is presently known of the subatomic world. The authors' interpretations and extrapolations of it have not been subjected to any decisive tests, and it is not clear that they ever could be. Once upon a time it was the province of philosophy to propose ambitious and outlandish theories in advance of any concrete evidence for them. Perhaps science, as Professor Hawking and Mr Mlodinow practice it in their airier moments, has indeed changed places with philosophy, though probably not quite in the way that they think."
The , Dr. , said, "Science can never prove the non-existence of God, just as it can never prove the existence of God."
Dr. Fraser N. Watts said "a creator God provides a reasonable and credible explanation of why there is a universe, and ... it is somewhat more likely that there is a God than that there is not. That view is not undermined by what Hawking has said."
British scientist
also criticized the book in an interview with : "Of course they can make whatever comments they like, but when they assume, rather in a -like way, that they have all the answers, then I do feel uncomfortable." She later claimed her Taliban remarks were "not intended to be personal", saying she "admired Stephen Hawking greatly" and "had no wish to compare him in particular to the Taliban".
