If you find problems, please file a report so that we can fix them.

The big changes since 2.0a2:

• Several Android fixes to handle recent SDK changes by Google. For anyone using Android, you’ll need to install 2.0a3. The Android page on the Wiki has also been updated.
• Fixed a regression in 2.0a2 that prevented serial from working on OS X.
• Tracked down a problem on OS X 10.7 (Lion) where the mode and open menus on the toolbar disappeared immediately.

The full revisions list with the gory details:

PROCESSING 2.0a3 (REV 0202) – 5 November 2011

Some weekend bug fixing and regression repair for the recent alpha releases.

Also several Android fixes to get things working again with more recent
updates from Google. You’ll need to upgrade to this version of Processing
in order to continue using Android mode.

Long version: this is a tally of the number of unique users who run the Processing environment every four weeks, as measured by the number of machines checking for updates.

Of note:

• In spite of the frequently proclaimed “death of Java” or “death of Java on the desktop,” we’re continuing to grow. This isn’t to say that Java on the desktop is undead, but this frustrating contradiction presents a considerable challenge for us… I’ll write more about that soon.
• There’s a considerable (even comical) dip each January, when people decide that the holidays and drinking with their family is more fun than coding (or maybe that’s only my household). Things also tail off during the summer into August. These two trends are amplified due to the number of academic users, however other data I’ve seen (web traffic, etc) suggests that the rest of the world actually operates on something like the academic calendar as well.

About the data:

• This is a very conservative estimate of the number of Processing users out there. Our software is free — we don’t have a lot to gain by inflating the numbers.
• This covers only unique users — we don’t double count the same person in each 4-week period. Otherwise our numbers would be much higher.
• This is not downloads, which are also significantly higher.
• This is every four weeks, not every month. Unless there are 13 months in a year. Wait, how many months are in a year?
• This only covers people who are using the actual Processing Development Environment — no Eclipse users, etc.
• Use of processing.js or spinoff projects are not included.
• This doesn’t include anyone who has disabled checking for updates.
• This doesn’t include anyone not connected to the net.
• The unique ID is stored in the preferences.txt file, so if a single login is used on a machine, that’s counting multiple people. Conversely, if you have multiple machines, you’ll be counted more than once.
• Showing the data by day, week, or year all show the same overall trend.

This is a pretty lame visualization of the numbers, and I’m not even showing other interesting tidbits like what OS, version, and so on are in use. Maybe we can release the data if we can figure out an appropriate way to do so.

The long story is that Chris Lonnen contacted me in the spring about applying for the Google Summer of Code (SoC) program, which I promptly missed the deadline for. But we eventually managed to put him to work anyway, via Fathom (our own SoC army of one, with Chris working from afar in western New York) with the task of working on a new editor that we can use to replace the current Processing Development Environment (the PDE).

After some initial work and scoping things out, we settled on the Eclipse RCP as the platform, with the task of first making a plug-in that works in the Eclipse environment (everything in Eclipse is a plug-in), which could then eventually become its own standalone editor to replace the current PDE.

Things are currently incomplete (again, see the Wiki page for more details), but give it a shot, file bugs (tag with Component-Eclipse when filing), and help lend Chris a hand in developing it further. Or if you have questions, be sure to use the forum. Come to think of it, might be time for a new forum section…

Built with Processing and AVR-GCC.

(Thanks to Golan, who pointed out this link.)

Also be sure to keep an eye on the Wiki for Android updates:
http://wiki.processing.org/w/Android

(By the time you read this, there may be newer pre-releases like 0192, or 0193, and so on. Use those instead.)

Release notes for the 0191 update follow. And we’ll be doing a more final release (1.3 or 2.0, depending) once things settle a bit.

Processing Revision 0191 – 30 September 2010

Bug fix release. Contains major fixes to 3D for Android.

[ changes ]

+ Added option to preferences panel to enable/disable smoothing of text inside the editor.

+ Added more anti-aliasing to the Linux interface. Things were downright ugly in places where defaults different from Windows and Mac OS X.

[ bug fixes ]

+ Fix a problem with Linux permissions in the download.
http://code.google.com/p/processing/issues/detail?id=343

+ Fix ‘redo’ command to follow various OS conventions.
http://code.google.com/p/processing/issues/detail?id=363
Linux: ctrl-shift-z, macosx cmd-shift-z, windows ctrl-y
http://en.wikipedia.org/wiki/Table_of_keyboard_shortcuts
http://developer.apple.com/mac/library/documentation/

+ Remove extraneous console messages on export.

+ When exporting, don’t include a library multiple times.

+ Fixed a problem where no spaces in the size() command caused an error.
http://code.google.com/p/processing/issues/detail?id=390

[ andres 1, android 0 ]

+ Implemented offscreen operations in A3D when FBO extension is not available
http://code.google.com/p/processing/issues/detail?id=300

+ Get OpenGL matrices in A3D when GL_OES_matrix_get extension is not available
http://code.google.com/p/processing/issues/detail?id=286

+ Implemented calculateModelviewInverse() in A3D
http://code.google.com/p/processing/issues/detail?id=287

+ Automatic clear/noClear() switch in A3D
http://code.google.com/p/processing/issues/detail?id=289

+ Fix camera issues in A3D
http://code.google.com/p/processing/issues/detail?id=367

+ Major fixes for type to work properly in 3D (fixes KineticType)
http://code.google.com/p/processing/issues/detail?id=358

+ Lighting and materials testing in A3D
http://code.google.com/p/processing/issues/detail?id=294

+ Generate mipmaps when the GL_OES_generate_mipmaps extension is not available.
http://code.google.com/p/processing/issues/detail?id=288

+ Finish screen pixels/texture operations in A3D
http://code.google.com/p/processing/issues/detail?id=298

+ Fixed a bug in the camera handling. This was a quite urgent issue, since affected pretty much everything. It went unnoticed until now because the math error canceled out with the default camera settings.
http://forum.processing.org/topic/possible-3d-bug

+ Also finished the implementation of the getImpl() method in PImage,  so it initializes the texture of the new image in A3D mode. This makes the CubicVR example to work fine.

[ core ]

+ Fix background(PImage) for OpenGL
http://code.google.com/p/processing/issues/detail?id=336

+ Skip null entries with trim(String[])

+ Fix NaN with PVector.angleBetween
http://code.google.com/p/processing/issues/detail?id=340

+ Fix missing getFloat() method in XML library

+ Make sure that paths are created with saveStream(). (saveStream() wasn’t working when intermediate directories didn’t exist)

+ Make createWriter() use an 8k buffer by default.

More bug fixes, and one new treat for OS X users. Hopefully we’re about set
to call this one 1.2. Please test and report any issues you find.

[ additions ]

+ On Mac OS X, you’re no longer required to have a sketch window open at
all times. This will make the application feel more Mac-like–a little
more elegant and trendy and smug with superiority.

+ Added a warning to the Linux version to tell users that they should be
using the official version of Java from Sun if they’re not.
http://wiki.processing.org/w/Supported_Platforms#Linux
There isn’t a perfect way to detect whether Sun Java is in use,
so please let us know how it works or if you have a better idea.

[ fixes ]

+ “Unexpected token” error when creating classes with recent pre-releases.
http://code.google.com/p/processing/issues/detail?id=292

+ Prevent horizontal scroll offset from disappearing.
Thanks to Christian Thiemann for the fix.
http://code.google.com/p/processing/issues/detail?id=280
http://code.google.com/p/processing/issues/detail?id=10

+ Fix NullPointerException when making a new sketch on non-English systems.
http://code.google.com/p/processing/issues/detail?id=283

+ Fixed a problem when using command-line arguments with exported sketches
on Windows. Thanks to davbol for the fix.
http://code.google.com/p/processing/issues/detail?id=303

+ Added requestFocusInWindow() call to replace Apple’s broken requestFocus(),
which should return the previous behavior of sketches getting focus
immediately when loaded in a web browser.
http://code.google.com/p/processing/issues/detail?id=279

+ Add getDocumentBase() version of createInput() for Internet Explorer.
Without this, sketches will crash when trying to find files on a web server
that are not in the exported .jar file. This fix is only for IE. Yay IE!

[ mixed bag ]

Android SDK requirement is now API 7 (Android 2.1), because Google has deprecated API 6 (2.0.1).

More Linux PDF fixes from Matthias Breuer. Thanks!

PDF library matrix not reset between frames. (Fixed in 0185.)
http://dev.processing.org/bugs/show_bug.cgi?id=1227

Updated the URLs opened by the software to reflect the new site layout.
http://code.google.com/p/processing/issues/detail?id=278

Updated the included examples with recent changes.

PROCESSING 0185 – 20 June 2010

Primarily a bug fix release. The biggest change are a couple tweaks for problems caused by Apple’s Update 2 for Java on OS X, so this should make Processing usable on Macs again.

[ bug fixes ]

+ Fix for Apple bug that caused an assertion failure when requestFocus() was called in some situations. This was causing the PDE to become unusable for opening sketches, and focus highlighting was no longer happening.
http://code.google.com/p/processing/issues/detail?id=258
http://dev.processing.org/bugs/show_bug.cgi?id=1564
http://dev.processing.org/bugs/show_bug.cgi?id=1569

+ Fixed two bugs with fonts created with specific charsets.

+ Fix from jdf for PImage(java.awt.Image img) and ARGB images. The method “public PImage(java.awt.Image)” was setting the format to RGB (even if ARGB)

+ Large number of beginShape(POINTS) not rendering correctly on first frame
http://dev.processing.org/bugs/show_bug.cgi?id=1572

+ Fix for PDF library and createFont() on Linux, thanks to Matthias Breuer.
http://dev.processing.org/bugs/show_bug.cgi?id=1566

+ Fix from takachin for a problem with full-width space with Japanese IME.
http://dev.processing.org/bugs/show_bug.cgi?id=1531

+ Reset matrix for the PDF library in-between frames also added begin/endDraw between frames
http://dev.processing.org/bugs/show_bug.cgi?id=1227

[ additions ]

+ Add the changes for “Copy as HTML” to replace the “Copy for Discourse” function, now that we’ve shut down the old YaBB discourse board.
http://code.google.com/p/processing/issues/detail?id=271

+ Option to disable re-opening sketches when you start Processing. The default will stay the same, but if you don’t like the feature, alter your preferences.txt file to change:
last.sketch.restore=true
to the following:
last.sketch.restore=false
The issue was originally filed here:
http://dev.processing.org/bugs/show_bug.cgi?id=1501
http://code.google.com/p/processing/issues/detail?id=245
However the main problem with this is that due to other errors, the wrong sketches are being opened, sketches are sometimes forgotten, or windows are opened concurrently on top of one another, creating a bad situation:
http://code.google.com/p/processing/issues/detail?id=177
http://code.google.com/p/processing/issues/detail?id=179
Those bugs are not yet fixed, but will be addressed in future releases.

+ Option to change the default naming of sketches via preferences.txt.
First, you can change the prefix, which defaults to:
editor.untitled.prefix=sketch_
And the suffix is handled using dates. The current default (since 1.0) is:
editor.untitled.suffix=MMMdd
Or if you want to switch back to the old (six digit) style, you could use:
editor.untitled.suffix=yyMMdd
http://dev.processing.org/bugs/show_bug.cgi?id=1091

+ Updated bundled JRE/tools to 6u20 for Windows and Linux

+ Several SVG fixes and additions, including some tweaks from PhiLho. These changes will be documented in a future release once the API changes are complete.

+ Added option to launch a sketch directly w/ linux. Thanks to Larry Kyrala.
http://dev.processing.org/bugs/show_bug.cgi?id=1549

+ Pass actual exceptions from InvocationTargetException in registered methods, which improves how exceptions are reported with libraries.

+ Added loading.gif to the js version of the applet loader. Not sure if this is actually working or not, but it’s there.

[ android ]

+ Added permissions for INTERNET and WRITE_EXTERNAL_STORAGE to the default AndroidManifest.xml file. This will be addressed in greater detail here:
http://code.google.com/p/processing/issues/detail?id=275
And with the implementation of code signing here:
http://code.google.com/p/processing/issues/detail?id=222

+ Lots of work happening underneath with regards to Android, more updates soon as things start evening out a bit.

+ Defaulting to a WVGA screen for the default Processing AVD.

Has a couple nice visual touches that prevent it from looking like YAHSVPOQUFOTI (yet another highly-stylized visualization piece of questionable utility found on the internet). Also cool to see it was built with Processing.js.
