The latest bug fix releases 2.8.6 and 2.12.3 have been released according to our release road map.

For a list of fixed issues see the commits to 2.8 and commits to 2.12, respectively.

Many of you out there may be wondering ‘when are we going to release QGIS 3.0?’. Last year (2015) we started investigating when and how we would release QGIS 3.0. We promised (see Anita Graser’s post about this) that we would convey clearly to our users and developers our plans well before making the QGIS 3.0 release. In this post I will try to lay out some of the considerations for a QGIS 3.0 release and at the end of this post there is an opportunity for you to present your ideas.

Why 3.0?

Typically (when following semantic versioning) a major release is reserved for times when you break the API of your software. Breaking API is not a trivial decision for the QGIS project since we have hundreds of thousands of users out there who depend on QGIS to ‘just work’, and many developers who need to maintain third party software written on top of the QGIS API.

From time to time breaking the API is necessary to accommodate updating the architecture with improved approaches, new base libraries and fixes to sub-optimal decisions made in the past.

What are the implications of breaking the API?

One of the reasons we are hesitant about releasing an API breaking QGIS 3.0 release is that it will have a huge impact, potentially breaking the hundreds of plugins in the plugin repository. Plugins would no longer compatible with new API and plugin authors would be required to manually review their plugins to identify and update  the places in their plugins where the code is no longer compatible with the new API.

The breadth of the updates required depends largely on

• how many backwards incompatible changes we make to the API
• how many places plugin authors have used parts of the API which have changed

I will talk more about how we can mitigate API breaking changes  further on in this article.

What will be the key changes for 3.0?

There are four key areas that we are looking to change in 3.0:

• Updating Qt4 to Qt5: This is the basic set of libraries on which QGIS is built and provides a high level, platform independent abstraction layer for building a graphical user application. Qt also provides libraries for carrying out disk i/o, networking operations, and graphics drawing operations (key functionality for QGIS). Qt4 (on which QGIS is currently based) is now not actively being developed by the Qt library maintainers and we are expecting to experience problems in the near future building Qt4 for some platforms (e.g. OS X) or having readily accessible binaries  (e.g. Debian Testing and the upcoming release of Debian “Stretch”). Making QGIS work with Qt5 has already been worked on (chiefly by Matthias Kuhn) who together with Marco Bernasocchi produce the Android “QField” port of QGIS which is based completely on Qt5. There are however some outstanding limitations in the newer Qt5 that impact on QGIS – in particular with the embedded web browser widgets (used chiefly in the QGIS composer but also a few other places in QGIS).
• Updating PyQt4 to PyQt5: These are the python language bindings for Qt which the QGIS python API relies on. When we shift to the Qt5 C++ library, we also want to shift to the updated PyQt5 python library so that we can benefit from the new Qt5 API within the python environment too.
• Updating Python 2.7 to Python 3: Currently we bundle in Python 2.7 in our windows installers and require 2.7 on other platforms where we do not co-bundle Python with QGIS. Python 3 is the latest version of python and is recommended by the Python project. Python 2 is slightly incompatible with Python 3 (in much the same way as QGIS 2 -> QGIS 3 will be incompatible). The python developers have made Python 3 largely backwards compatible to Python 2, but the compatibility in the opposite direction is not as good.
• Improving the QGIS API itself: One of the issues with maintaining API compatibility between releases is that you have to live with your design choices for a long time. In QGIS we try our best not to break the API within a minor release series – not always with success as the more hard core developers will attest to. Releasing an API incompatible version of QGIS for 3.0 will give us an opportunity to ‘clean house’ by fixing things in the API that we are unhappy with. You can see a provisional list of proposed API changes for 3.0 by looking at the 3.0 API issues list.

Mitigating 3.0 API breakages

As I mentioned the 3.0 release will break API from the 2.x release of QGIS and there is the potential that many existing plugins, applications and other code that rely on the current API will be broken. So what can we do to mitigate the changes? Matthias Kuhn, Jürgen Fischer, Nyall Dawson, Martin Dobias and other core developers have been looking at ways to mitigate the number of API breaking changes whilst still advancing the QGIS codebase to be based on the next generation of libraries and its own internal API. During our last QGIS Project Steering Committee meeting we ran through various possibilities. Matthias Kuhn kindly joined the meeting to help clarify our options going forward which I have tried to summarise in the table below:

There are two key things to note about Matthias’ proposal:

• In the first phase, work would be done in the QGIS 2.x series to complete support for Qt5, PyQt5, Python 3.0 whilst still supporting Qt4, PyQt4 and Python 2.7. This implies that all changes made in the first phase would be backwards compatible with previous QGIS 2.x releases. Python wrappers will be introduced so that the old PyQt4 API can still mostly be used when compiling against Qt5, PyQt5, Python 3.0. When using QGIS compiled against Qt4, PyQt4 and Python 2.7 there would be no compatibility breakage.
• In the second phase, we would work to produce QGIS 3.0 which introduces a number of API breaking changes, completely removing Python 2.7, Qt4 and PyQt4 support. The python wrappers produced in the first phase would be kept and relied on to ensure that a large proportion of python code (plugins, scripts etc.) developed for QGIS 2.x releases continue to work in QGIS 3.x releases. In this phase we would also introduce the QGIS API changes which may break some plugins. To address this we will provide a migration guide to try to ease the process for those moving from code depending on the QGIS 2.x releases to the QGIS 3.x releases.

Caveat emptor

There are a couple of ‘gotchas’ that we should raise at this point as the above makes the migration to QGIS 3.0 sound fairly painless.

1. The first thing we should emphasise is that while the approach laid out above tries to minimise the amount of work python script and plugins writers have to do, this will not be a 100% effort free solution for python coders using QGIS. There will very likely be cases where code needs to be adjusted and in all cases at the very least it will probably need to be reviewed in order to ensure that it still functions properly.
2. There is no formal funding set aside to pay for developers to spend their time working on the migration process. Because of this it is going to be incredibly hard to give accurate timelines as to how long each part of the process will take. We need to take this uncertainty into account in our planning. Of course we welcome donations to help make this happen.
3. There may be developers and institutions out there funding new features for the QGIS 2.x series and this may affect your work. You should include in your project plans and budgets some allocation to cope with the migration to the QGIS 3.x platform.
4. If we do the work in the ‘master branch’ there may be a protracted time during which our master branch is unstable and in flux due to ongoing updates towards QGIS 3.0.
5. If we do the work in a ‘3.0 branch’, we run the risk that the 3.0 development may drag on longer unless there is a devoted group of developers working on it and getting it ready to merge to master.

Proposals

In the light of all the above information, we propose one of two courses of action:

Proposal 1:

Do an interim release of 2.16 and then commence work on 3.0 in master with an 8 month development window. Work on 3.0 related stuff could already begin in 2.16  (see python3/pytq5), only incompatible changes have to be postponed to post 2.16.

Advantage: Main focus of work would be in master branch. Work scheduled for the near future can be released in expected timelines. Plugins will continue to work with master. People can start to write and test their code in a portable manner.

Disadvantage: Difficult to determine timelines as we don’t have funding

Proposal 2:

Create a long running 3.0 branch for the port to Qt5, Python 3.0 and PyQt5 and call for developers to get their 3.0 work in there. Continue with 2.x releases with the usual frequency until 3.0 is ready.

Advantage: We can release it ‘when it’s ready’. If there is no funding for 3.0 work subsequent releases are not jeopardised.

Disadvantage: Duplication of effort as work in master coming in needs to be ported over to the 3.0 branch.

Alternative proposals

Do you have an alternative proposal? We would like to get all the proposals on the table so that we (the PSC in consultation with core developers) can make the best judgement of how to approach the nitty-gritty process of managing the QGIS 3.0 development process. If you wish to submit a proposal, please send it to me ([email protected]) with the subject line ‘QGIS 3.0 Proposal‘. Please keep your proposal very short and succinct as we just need the high level concepts.

Here is the proposal submitted by Matthias Kuhn that you can use as a reference of how we might like  a proposal to look:

QGIS 2.16 Release as usual in 4 months

-> PyQt5 Support
-> Python 3 Support
-> Wrapper library for PyQt4/PyQt5
-> Maybe a helper transition script that does 80% of the rewrite
-> All old plugins still work
-> Some python code is updated (console, plugin manager, processing) to
have some guidelines and experience how to update python code
-> For future debian, mac osx… versions there’s a qt5 version around
(with almost no plugins working)

During the same time: make some noise that QGIS 3 is coming and we need
everybody to put some money and dev time aside for it and that it’s
going to be amazing.

—————-

After that: 8 months break for 3.0 (maybe some betas after 4 months and
every month after)

Back to normal, everybody happy – except the lazy plugin devs who didn’t
update –

Local governments on the municipality or provincial level often have to deal with DXF/DWG/DGN documents delivered from architects, urban planners or engineering companies. As an example, cadastral or utility offices or companies often have to import CAD documents to either check deliveries about correctness or import selected objects into their central database. Another requirement is being able to visualize planned objects, such as buildings or bridges alongside with the cadastral data.

QGIS lacks proper import of CAD data so far – DXF files can only be imported on very basic levels (without styling and labeling), DWG files can’t be imported at all.

A requirements document has been written to implement import of DXF/DWG (and potentially also DGN) files into QGIS, while maintaining styling, labeling, 3D, curves and blocks.

The company Norbit, with Jürgen Fischer, submitted an offer. Jürgen is a long-term QGIS developer and QGIS.ORG board member. Norbit has extensive experience with bridging GIS and CAD.

The plan is to use the Teigha library of the OpenDesign Alliance (ODA) to read the CAD documents. Either QGIS.ORG or OSGeo would become a member of the ODA, to get access to the source code and for distributing the Teigha libraries with QGIS binaries.

At this time we are looking for organisations or companies that help funding the effort. The offer from Norbit is over 32k €. We are looking for institutional crowd funders with minimum contributions of 1k Euros. If you are interested in contributing, please contact by mail at andreas (at) qgis (dot) org. We can send you an invoice for your contribution.

Addition: if you want to do smaller, targeted donations, please use the regular donation channels and mention “CAD import” in the payment instructions.

Last weekend (November 5th – November 8th, 2015) was a special occasion for the QGIS Project – we convened the 14th our ‘hackfest’ meeting!

QGIS hackfests are events where an organiser provides a space for collaboration and members of the community converge and self-organise to improve the QGIS project. We are very much dependent on the good will of our hosts – typically universities – for providing these spaces and the logistics needed to manage the provision of accommodation, food, internet and other needs of our participants over the duration of the hackfest. For this event our gracious hosts were Universitas de Las Palmas de Gran Canaria. Our presence at the University was endorsed and facilitated by:

Our heartfelt thanks to all of the people who worked so hard to make this event happen, and to the participants who travelled from far and wide to attend the event. These events are a significant factor in the success of the QGIS project – they allow our developers and contributors to meet face to face and delve deep into technical issues that would be impossible to do under the somewhat disconnected collaboration environment provided by the internet.

Key Activities

QGIS Sponsorship

Many of the costs not covered by our hosts were covered from central QGIS.org funds including food and travel costs for a number of participants. These funds originate from our donors and sponsorships and are an invaluable resource for the project to allow us to facilitate these events and move the development of QGIS forward. We encourage you to donate to the QGIS or become a sponsor if you would like to foster further innovation and support the long terms goals of the project.

More Information

If you would like further information about what was covered in the event, and to get a feel of the general atmosphere of the event, check out some of these links:

• Pablo Fernández Moniz created this collation of photos from the event.
• Anita Graser compiled this great storify timeline of the event.
• Alessandro Pasotti compiled a really great report of his experiences at the event.

I will update the list above as more reports backs become available.

Thanks

With thanks from your project chair and the whole QGIS community,

In the 12th episode of the QGIS podcast, Tim Sutton and Victor Olaya talk about what they have been doing during the latest QGIS developer meeting, present the latest QGIS enhancement proposals (QEPs), chat about the Processing framework and much more!

The QGIS project is growing in size, number of contributors/contributions and code complexity. This introduces challenges for the project, especially for maintaining quality. Maintaining and improving quality is one of the main concerns of the QGIS.ORG board and some core developers.

Past and current QA efforts

Tim Sutton introduced a first unit test framework several years ago. But it wasn’t very visible then and passing the tests as a prerequisite to make changes to master wasn’t enforced. About a year ago, Matthias Kuhn introduced automated unit testing for the Linux builds – using Travis continuous integration testing. At our github page you can always see whether the master version builds fine and whether the tests are passing – see the green “Build passing” button at the beginning of the Readme.md file.

Since then, OS X automated building/testing was added. Pull requests (new contributions from developers) can be tested prior to integration into the master branch. Another effort was to use coverity code scans to detect memory leaks. Nyall Dawson and others did a lot of improvements/fixes due to this automated code scans.

Upcoming challenges

There is still a lot to do regarding quality and automated testing. Because continuous integration tests were only introduced about a year ago, it means that still a lot of areas in the code base remain untested. Also, the current unit tests do not test GUI interactions. There is an ongoing discussion if critical classes should have unit tests enforced for any code changes. Finally, our bug queue at http://hub.qgis.org/projects/quantum-gis/issues is still quite long, with lots of bigger and minor issues.

Your financial support really matters!

This is where your donations and sponsorships come in. For the past 3-4 releases we were able to pay 2-4 developers who worked for several days concentrating on bug fixing. For QGIS 2.12 we had Nyall Dawson, Jürgen Fischer and Larry Shaffer working on bug fixing. We also financially support Giovanni Manghi for working on our bug tracker (e.g. classifying issues correctly, trying to reproduce the issue, ask bug reporters for more details).

Now – you may wonder why they didn’t fix all the “BLOCKER”s first and then continue on with “HIGH”, “NORMAL” “LOW”  issues – and why a lot of unreported issues and issues with label “LOW” were also fixed? The answer is that it is often more efficient for the developers to concentrate on a certain part of the code – e.g. concentrating on geometry, labeling and editing issues, as Nyall did for this round of bug fixing. This means that he would not only fix issues labeled as “BLOCKER” or “HIGH” but also other bugs that are in the same code. Finally, not all of the “Blocker” and “High” bugs are reproducable or the issue may be much too hard/time consuming to fix.

Due to your financial support, the 3 developers were able to fix the following list of issues for the QGIS 2.12 release – many of the fixes also get back-ported to QGIS 2.8 LTS release:

Transition
The QGIS PSC (Project Steering Committee) is in transition to becoming a Board. We are registering the project as a Swiss ‘Verein‘ (Association) which will be known as QGIS.ORG and will function as a not-for-profit company, serving the interests of the QGIS project.  The motivation for the transition to a legal entity is described in QGIS QEP (QGIS Enhancement Proposal) #16. The board will be constituted of the same members of the PSC but will gain the executive responsibilities required of our Verein statutes.

New chair and vice-chair

Our long time project founder, Gary Sherman, has stepped down from his role as project chair. I (Tim Sutton) have been elected by the QGIS PSC as Gary Sherman’s replacement by the incoming Board. In addition Paolo Cavallini has been elected as vice chair. Gary will continue to serve as an active voting member of the Board, and will maintain life-long honorary membership on the board.

A special note of thanks

In a world where proprietary GIS software licenses cost many times more than the annual income of most of its citizens, free access to spatial visualisation and analysis tools through QGIS (and its constituent projects such as GRASS, GEOS and GDAL) is a profoundly disruptive force for good.

QGIS is a available to anyone with a reasonably modern computer. It makes the wise utilisation of the earth’s scarce resources and the ability to take care of its citizen’s civic and humanitarian needs based on sound spatial decision-making, that much more possible for a huge swathe of society which would otherwise have been disenfranchised.

Even in developed societies where finance is not necessarily the limiting factor, we cannot underestimate the impact of a software platform that is a freely extensible and shared body of knowledge. QGIS is a platform that enhances the ability of governments and private organisations to deliver services that deeply enrich the lives of their citizens and customers.

Gary’s selfless contribution of the QGIS source code has thus had a far reaching affect on many people’s lives – including my own. Under Gary’s stewardship, the project has evolved from a very basic simple GIS data browser that ran on one platform and could only work with PostGIS data, to a fully-fledged production-ready GIS that can be used on the desktop, in your own custom applications and to serve web maps and services.

Gary has been and will remain an inspirational figure to all of us in the QGIS project – the project he started 13 years ago in 2002. We look forward to his continued involvement on the Board.

Going forward

Our goal as the QGIS.ORG Board is to continue the work started by Gary and to position QGIS as the de facto desktop GIS application, capable of providing a wide range of functionality and richness of features, so that it is no longer necessary to use proprietary GIS software to understand and manage our world.

We are looking for funders for the QGIS.ORG non-profit company. As a foundation project to many humanitarian, municipal, government, NGO, conservation and industry related FOSS tools, we would like to secure funding for the core QGIS project to hire full-time staff so that we can improve the quality and functionality of QGIS for all our users.

To date we have subsisted mainly on micro donations and small-scale sponsorships for which we are very grateful (keep them coming!). This has been very useful but has never take us to the point where we can employ staff full-time to work solely for the good of the project. We would like to establish a team of full-time developers, documentation writers etc.….so we have quite a mountain to climb!

Over the coming months we will be actively seeking out new sources of funding to support these goals, whilst never losing sight of our core principles of Open Governance, Open Source and Open Community. We hope you will join us and support us in this exciting new chapter of the QGIS project!

Tim Sutton
Incoming QGIS Board Chair

QGIS already supports various different renderers, such as
categorized, rule-based, point-displacement, heatmap, etc. This allows for advanced cartographic representations. In addition, there are plugins available, such as “qgis2threejs” or “QGIS Globe”, which allow to view and export QGIS data in the third dimension. While these plugins are very useful, they also have limitations: they are not fully integrated with the QGIS styling mechanisms and can’t be integrated in the QGIS print composer for  high-quality printing.

This crowd funding project aims to extend QGIS renderers with oblique views. The third dimension of the polygon is controlled by an attribute or expression and global angles. The representations can be combined with other QGIS styling options, such as symbol levels, layer effects, categories and rules. Applications are rendering buildings according to their actual heights (similar to Google maps 2.5d rendering) or thematic maps where the polygons are extruded according to an attribute to be represented.

This project is primarily financed by ADUGA and the regional council of Picardy in France. However, of the 20k Euros, 5k are still missing, to fully implement the project.

Thank you for helping us out by contributing to this crowd funding campaign over at OpenGIS.

This week we have more great news from Jürgen Fischer, our release manager:

“QGIS is a user friendly Open Source Geographic Information System that runs on Linux, Unix, Mac OSX, and Windows.

We are very pleased to announce the release of QGIS 2.12 ‘Lyon’. Lyon was the host city to our developer meet up in April 2012.

Latest Release

This is another regular release following our four monthly schedule.  It again brings many nice new features to QGIS.

Please also note that we’re constantly keeping our long term release QGIS 2.8 ‘Wien’ in good shape to better suit more conservative production setups.

New Features in QGIS 2.12 ‘Lyon’

QGIS 2.12 includes many great new features, tweaks and enhancements to make the
most popular Free desktop GIS even more feature filled and useful.  Visit the visual changelog that highlights some of the new additions.

Whenever new features are added to software they introduce the possibility of new bugs – if you encounter any problems with this release, please file a ticket on the QGIS Bug Tracker (http://hub.qgis.org).

The source code and binaries for Windows, Debian and Ubuntu are already available via the large download link on our home page: http://qgis.org.  More packages will follow as soon as the package maintainers finish their work. Please revisit the page if your platform is not available yet.”

Thanks to community member Sorin Călinică, there is now a Romania version of the QGIS User Survey available. We look forward to seeing your responses!

Thanks to QGIS Community member Alexander Bruy, our Ukranian users can now also participate in the QGIS User Survey in their native language!

Another great community contribution – you can now participate in the QGIS user survey if you are a Spanish speaker! Thanks to Luigi Pirelli and Victor Olaya for contributing this.

Another wonderful contribution from the QGIS community, the 2015 QGIS User survey is now available in French! Thanks for René-Luc Dhont for contributing the French translations.

Thanks to our awesome community, the QGIS User survey is now available in Portuguese! We are looking forward to hearing how the Portuguese speaking community is using QGIS!

Dear QGIS community,

In the last few years we have been steadily improving the amount of funding we are able to accumulate in the QGIS project. Our goal in obtaining funding is always to ‘make QGIS better’. Up until now we have focussed funding on high profile aspects of the project: Funding regular hackfests, paying for bug fixing work prior to releases, funding infrastructure such as servers, domain name registrations etc.

With improved funding levels we now have the opportunity to also start addressing some of the many less obvious components of QGIS that badly need attention, but often don’t attract volunteers. In our PSC meetings it was agreed that we would start this initiative by funding one or more experienced users to improve the QGIS manual. Here, briefly, is the vision:

As an experienced QGIS user you currently have two main resources: The QGIS manual and the QGIS training manual. In this call we focus on the manual, which is already an excellent resource on available functionality in QGIS.

• The challenge is to keep it synchronised with all new features, and examples and figures often run the risk of being out of date. This is the case already for several chapters of the manual for the latest QGIS releases and we want to start optimizing this.

  We would love to see the QGIS manual providing a readable narrative explaining the purpose (with images and illustrations if needed) of each feature. It can also provide short sample snippet where useful, which in many cases you can simply cut and paste into your code and then tweak to get started.

  For this funded effort we are thus seeking one or more individuals to lay the foundation for this work:

  * verify and improve the norms and guidelines of the documentation and
  especially its update process together with the PSC.
  * update the manual to include all features that are available within the latest QGIS release (2.12).
  * update figures, if necessary according to the defined guidelines (size, desktop-environment, resolution,…).
  * populate the manual with further short examples and improved descriptions, without competing with the training manual.
  * do these in a nice clear and concise writing style, taking inspiration from other software manuals, if available.

  If you think this is something you are able to do, please contact the QGIS PSC using this form and let us know!

  Best wishes,
  Otto

A note from Jürgen Fischer, our release manager, heralds the start of preparations for QGIS 2.12. We depend all users out there to test it and report issues so we can make the best possible release. An edit version of the email to the developer mailing list from Jürgen follows:

Hi,

I’d like to remind everyone that the 2.11 development cycle ended yesterday at
12:00 UTC. We are now in feature freeze on the road to the 2.12 release on 2015-10-23

Now we (the community) need to prepare QGIS for the release. No new features will be added anymore.

• Users, if not already begun, should now start
  extensive testing of master and report bugs on the QGIS hub.
• Developers should move their focus from creating new features to fixing bugs.
• Translators can can continue their work (we maintain all our translations on transifex now).

The nightly builds of QGIS testing available for Windows (download here), Linux (Debian and Ubuntu) and Mac
OS X (download here) are now effectively snapshots of what’s going to be released.  Except of course
for the bugs that are going to be fixed until release day.  For Windows there will also be weekly release candidates of the standalone installer. Lets keep up working together to make 2.12 another great release.

Jürgen

Dear QGIS developers

We will be holding our 14th hackfest in Gran Canaria over November 5th – November 8th, 2015. You can read more about the plans for this meet up and register your intention to attend on the hackfest wikipage. This is a developer centric hackfest where we invite coders, documenters, testers, graphic artists, translators and anyone else who is interested in improving QGIS for the benefit of all our users. General users of QGIS are of course also welcome to join us, but we will not be holding any specific user-centric workshops or talks like we do at our user conferences.

The QGIS hackfests are an important aspect of the project, playing an key role in facilitating collaboration and planning within the community of developers and contributors who combine their efforts to put out three releases of QGIS each year. We rely on the goodwill and sponsorship of our grateful users and their host organisations to financially sustain the QGIS project. If you are in a position of influence, we ask you to please consider sponsoring QGIS to support this hackfest and other project related activities.

We would like to thank Pablo Fernández Moniz and his co-organisers from Universidad de las Palmas de Gran Canaria for organising the event. If you are able to support his event organisation activities in any way, please contact him at [email protected]

We look forward to seeing your all there!

The QGIS Team
