Version 2.5.0:
The ffmpeg plugin has been refactored:
The core has been moved to a new library: imageio-ffmpeg.
That library provides platform-specific wheels that includes ffmpeg, so just pip install imageio-ffmpeg instead of the download step.
Note that this new library is py3k only.
Termination of ffmpeg subprocess is now more reliable.
The reader of the ffmpeg plugin now always reports inf as the number of frames. Use reader.count_frames() to get the actual number, or estimate it from the fps and duration in the meta data.
Removed CannotReadFrameError.
Other changes:
The avbin plugin has been depreacted and will be removed in a future version.
Imnproved speed for PIL and FFMPEG plugsins by avoiding memory copies.
Update the included tiffile library.
Support for SimpleITK.
Speed up tiffile plugin when writing to something else than a filename.
Fix that writing to a file object would not work for some plugins.
Can now pass image data to the write functions as anything that resolves to a numpy array with a numeric dtype.
One can now read from a memoryview.
Fix error related to paletted BMP with the Pillow plugin.
Improved logging.
Version 2.4.1:
Fix installation issue on flavors of Ubuntu 14.04 /w Python 2.7.
Use np.frombuffer instead of np.fromstring in some cases.
Version 2.4.0:
Renamed Image class to Array and add documentation for this ndarray subclass.
Reading from HTTP and zipfiles has been improved and better documented.
Improvements to reading and writing of Tiff metadata.
Better dealing of tifffile dependencies on Python 2.7.
Reader for the SPE format.
Better termination of FFMPEG when reading from webcam.
FFMPEG support for reading 16bit videos
+ $fcc_before_send, when set, causes Fcc to occur before sending instead of
afterwards. When set, the message is saved as-sent; please see the
documentation for details.
This is one of the most popular Doom source ports.
It enhances Doom with things like:
- Free Look
- OpenGL renderer
- Heretic support,
- TCP/IP networking
and much more.
Doom Legacy can play Doom, Boom, Marine's Best Friend (MBF), and Heretic maps.
In addition to the original games by id Software and Raven Software, there are
hundreds of free, fan-made maps available on the Internet. These maps are
typically distributed as PWAD files, which are not fully self-contained.
For each game you will also need the corresponding IWAD data file, which
contains all the graphics, wall and floor textures, sounds, and music for that
game. For example, if you want to play Doom II maps, you'll need the IWAD file
doom2.wad, or one of the free replacements.
Legacy has implemented the fundamental and de-facto-standard Boom extensions,
and the Marine's Best Friend (MBF) extensions. Legacy also has implemented
among other things 3D floors, swimmable water and other special effects using
extended linedef codes, and supports the FraggleScript scripting language.
This package contains the SDL build of Doom Legacy.
Fixes builds with newer GCC.
This is a small release that improves support for a few bankswitching schemes:
* Added support for CDFJ bankswitching type (Galaga, Wizard of War, etc).
* Allow the DPC+ scheme to not enable playfield 'jitter' effect for certain
older DPC+ driver versions; this allows 'Epic Adventure' ROM to finally
work in Stella.
5.1.3 to 6.0: (December 23, 2018)
* Note: because of major TIA sound changes, the state file format has
changed, and old state files will not work with this release.
* New cycle exact audio core based on work by Chris Brenner (crispy);
greatly improved audio emulation accuracy (i.e. E.T., Ms. Pacman).
* Full rewrite of the audio subsystem; resample TIA output to target
sample rate directly in Stella.
* Added option to force stereo sound for all ROMs, or to use the
setting on a per-ROM basis.
* Threading: decouple emulation from frame rendering.
* Main loop rewritten; emulating speed and timing is now much more
faithful (i.e. speed in Pick'n'Pile).
* Added preliminary support for 'CTY' bankswitching scheme and recently
released 'Chetiry' ROMs. Special thanks to SpiceWare for adding music
support to this scheme.
* UI modernization (new widget look, dialog titles added, dialogs
refactored).
* The bankswitch scheme can now be forced by naming the ROM with a
specific extension (ie: .f8s for F8SC, .fe for FE, etc). The
supported extensions are the same as the ones from HarmonyCart and
UnoCart.
* Audio settings replaced with new 'audio.xxx' settings.
* FPS setting replaced with speed setting for adjusting emulation speed.
* Extra functionality for Time Machine dialog (start/stop recording;
minor fixes).
* When logging messages to the System Logger, condense similar messages
that arrive in batches into fewer messages (including timestamps).
* Fixes for collision corner cases (during HBlank).
* Fixed excessive CPU usage while in UI modes (ROM launcher, debugger,
etc).
* The 'launcherexts' option has been replaced by a true/false option
named 'launcherroms', which specifies to show only ROMs or all files
in the ROM launcher.
* Changes in 'Game Properties' dialog
- 'Default' button now affects only current tab like in all other
dialogs.
- 'Display' and 'Console' tab changes are now immediate.
- Fixed bug when selecting 'Auto-detect' format for 50Hz ROMs
* Fixed bug in autodetecting Genesis controllers.
* Fixed bug with 'thumb.trapfatal' commandline argument; sometimes Stella
would lock up when encountering a fatal error instead of entering the
debugger and displaying a message.
* Fixed bug in reading from settings file with entries that were empty;
the parsing was failing. This affected the 'cpurandom' argument; when
all options in it were turned off, they were all turned on again during
the next program run.
* Fixed bug with 'hold' events; they are now released a short time after
starting a ROM.
* When starting Stella for the first time, the first ROM selected will
determine which path to use by default for subsequent runs.
* Fixed emulator crash when starting SaveKey ROMs from commandline with
SaveKey messages enabled.
* Fixed missing TV format update in frame stats dialog when switching
display type.
* Fixed missing debug color update when switching display type.
* 'Fill to scanline' now works for scanlines above current scanline too.
* The debugger 'uhex' command is now honoured in CDF and BUS schemes.
* When switching screenmodes, the sound is now paused and later resumed.
This fixes popping and cracking sounds apparent on some systems, notably
OSX when toggling windowed/fullscreen mode.
* State file format has been optimized to be smaller, and faster loading
and saving. This affects both the files saved to your computer as well
as Time Machine functionality.
* The ROM name saved in a PNG tEXt chunk now honours the 'snapname'
setting.
* Improved snapshots when phosphor is enabled.
* Updated PAL palette.
* Added 'Cartridge.StartBank' ROM property, to force a ROM to use a
specific bank for its reset vector.
* Added Developer setting, which breaks on reads from write ports. It
now detects such conditions in many more cases. This new way of
detecting RWP errors obsoletes the old '_rwport' debugger command,
which has now been removed.
* Added recently released 'Arkyology' prototype ROM to the database.
* Added 'Amoeba Jump' and 'Flappy' ROMs (from the Retron77) to the
database.
* Fixed 'Street Racer' and 'Video Olympics' ROMs to use paddles in both
ports.
* If using SDL 2.0.5 or above, the calculated desktop size now takes
the taskbar/dock into account (so windows should no longer overlap
those areas).
* For UNIX systems: in the ROM launcher, when using symlinks use the
symlink pathname instead of the underlying filesystem pathname.
* The UNIX builds now use the system-installed PNG and ZLIB libraries
by default.
* The Macintosh builds are now named 'macOS' throughout the codebase to
reflect the new naming from Apple.
* For better compatibility, the Windows 32-bit version does not require
SSE2 anymore.
* Updated included PNG library to latest stable version.
5.1.2 to 5.1.3: (June 10, 2018)
* Fixed crash in OpenBSD when quitting the app, which can also be
happening on other systems (no reports yet, but the problem is now
fixed for good).
* Fixed configure/build scripts to work natively under OpenBSD.
5.1.1 to 5.1.2: (May 20, 2018)
* Fixed bug with SaveKey autodetection; some ROMs were not correctly
detecting that a virtual SaveKey device was plugged in. This notably
fixes issues in "Super Cobra" and "Scramble" ROMs.
* Make previously mentioned ROMs use the SaveKey device by default.
* Fixed bug in UI navigation with joystick hat movement.
5.1 to 5.1.1: (February 21, 2018)
* Fixed bug in Stargunner ROM starting with a blank screen.
5.0.2 to 5.1: (February 4, 2018)
* Added "Time Machine" mode, which automatically creates save states
in user-defined intervals. The user can navigate back and forth within
these states inside the emulator and the debugger.
* Huge improvements to the disassembly view in the debugger and
disassembly files created:
- reformatting in debugger for better space utilization
- much improved code and data detection
- access tracking and indicators for TIA/IO/RAM adresses in disassembly
- break vector is tracked (if used)
- improved cycle count (page penalties, sums created in disassembly)
- improved handling of instruction masking opcodes (e.g. BIT)
* Fixed change tracking bug during rewind; changes were accumulated
instead of being displayed only for the last rewind step.
* Extended 'rewind' to take a second parameter which allows rewinding
multiple states.
* Added 'unwind' command, which undoes the latest rewind(s)
* Added '<' (unwind) button to debugger.
* Thumbulator support is not conditional any more.
* Moved various developer related settings in new Developer Settings
dialog. These settings now come in two groups (player/developer) and
allow switching all settings at once.
* Don't trap write accesses to the datastream pointers in CDF and BUS.
This fixes -dev.thumb.trapfatal 1.
* Complete rework of TV mode and ystart autodetection. The new
implementation is more robust and reduces startup time.
* Add two "grace lines" of black to the top of the frame when
autodetecting ystart.
* Fixed Genesis controller autodetect (Stay Frosty 2, Scramble, etc).
* Fixed a bug in ystart autodetection that could cause screen jumps.
* Fixed several bugs in holdselect, holdreset and holdjoyX commandline
arguments; these now work as expected.
* Fixed bug in TIA collision handling; it is now disabled in VBlank.
* Improve TIA PF collision handling during hblank; this fixes a bug in
Thrust ROM.
* Fixed wrong display of HM values in debugger after 'HMCLR' has been
executed.
* Fixed bug with the debugger 'savedis' command in Windows; it wasn't
actually saving the files at all. This has never been reported
before, so I guess it shows how many people use that functionality.
* The debugger 'savedis', 'saverom' and 'saveses' now save files in
a default, user-visible directory (see the documentation for more
information). In the case of 'saveses', the filename is now named
based on the date and time of when the command was entered.
* Fixed bug with saving snapshots in 1x mode; there was graphical
corruption in some cases. Such snapshots also now include any TV
effects / phosphor blending currently in use.
* Fixed regular-sized snapshots when phosphor effect was enabled;
sometimes the image was 'double-blended', resulting in a snapshot that
was too dark.
* Fixed crash when selecting 'CompuMate' as a controller type for a non-
CompuMate ROM; this controller type can no longer be manually
selected, and will be used automatically used for CompuMate ROMs.
* Fixed cheat codes, so 7 digits codes are now accepted as described in
the doc.
* Fixed swapped ports being displayed wrong in System Logs and debugger.
* Added options to erase the AtariVox/Savekey flash memory, either for
all ROMs or only the current one. Also added a message (configurable)
when the flash memory is accessed.
* Access to the AtariVox/SaveKey can be signaled with a message.
* Added new interface palette 'Light'.
* Frame stats display made transparent. Also it now displays the real
frame rate and if the developer settings group is enabled.
* Improved tab auto-complete in debugger.
* Added conditional traps and savestate creation to debugger.
* Added 'Options...' button to debugger which gives access to the options
menu during debugging.
* Added debugger pseudo-register '_cyclesLo' and '_cyclesHi', which give
the number of CPU cycles that have occurred since emulation started.
* Added debugger pseudo-register '_fcycles', which gives the number of
CPU cycles that have occurred since the frame started.
* Added debugger pseudo-register '_icycles', which gives the number of
CPU cycles of the last instruction.
* Extended debugger 'dump' command to take a second argument, indicating
the end of the range to dump data.
* Improved change tracking; more values are tracked and change tracking
now works in case of a break too.
* Added widgets for trackball and SaveKey/AtariVox controllers.
* Improved emulation of 'FE' bankswitch scheme (no user-visible changes,
but internally the emulation is much more accurate compared to the
real thing). Related to this, improved the debugger support for this
scheme (you can now switch banks in the debugger view).
* Added emulation of 7800 initial RAM values and Pause key.
* Added ROM properties for 'Scramble' ROMs, and updated info for all
"Champ Games" ROMs.
* Added ROM properties for 'Zippy the Porcupine' ROMs, and updated
info for all "Chris Spry (Sprybug)" ROMs.
* Support UNIX style builds (configure / make) on OSX with both
XCode / clang and g++.
* Fixed error when building with uClibc-ng for ARM (thanks to Sergio
Prado).
* Updated included PNG library to latest stable version.
5.0.1 to 5.0.2: (August 20, 2017)
* Improved emulation of Trakball controller, eliminating bias in left/
right directions. Thanks to Thomas Jentzsch for the idea and code.
Related to this, added 'tsense' commandline argument and associated
UI item, to allow changing sensitivity of mouse trackball emulation.
* Added preliminary support for multi-threading in the Blargg TV effects
code. This is still a WIP; more improvements are coming. Related to
this, further optimized the TIA rendering code. Also added 'threads'
commandline argument and associated UI item to enable/disable
multi-threading. Thanks to Thomas Jentzsch for the bulk of the work
in this area.
* Blargg TV effects now no longer cut off the right side of the image
(by several pixels) in certain cases.
* Updated CDF scheme to latest version from Spiceware. In addition,
this scheme now supports versioning, so older and newer ROMs will
continue to work.
* Fixed an annoying bug in Linux, where Alt-Tab'ing out of a window and
then back again would pass a 'Tab' key event to the app, which in
most cases would navigate to the next UI element.
* Fixed potential issue with state file saving and the debugger; under
certain circumstances a rewind would give a different state than
before (note that the state file format has changed because of this).
* Fixed lockups when entering the debugger under certain circumstances.
* The debugger 'listtraps' command now shows all traps set, not just
the first one(s).
* Reverted joystick changes for Decathlon ROMs from last release, as
it was added by mistake.
5.0 to 5.0.1: (July 23, 2017)
* Fixed issues in keypad, Genesis and various other controllers that use
INPTx registers; the emulation is now much more accurate in this area.
* Various 'Bumper Bash' and 'Decathlon' ROMs are marked as always having
all 4 directions on a joystick enabled, since they can't be played
properly otherwise.
* Added 'Hunchy II' from Chris Walton (cd-w) to ROM properties database.
* Codebase now uses C++14 features.
4.7.3 to 5.0: (July 16, 2017)
* Note: because of major TIA/6502/RIOT changes, the state file format
has changed, and old state files will not work with this release.
* Stella has moved from Sourceforge to Github.
* Completely new TIA core is now available, ported from 6502ts by
Christian Speckner (DirtyHairy). This new core is extremely accurate,
and matches real hardware in almost every test we've performed.
New features include:
- Meltdown emulates correct
- The lap number in Pole Positions displays correctly
- Artifacts in the mountains on Snoopy and the Red baron are gone
- Line artifacts in Title Match Pro Wrestling and Realsports Boxing
are fixed
- The spurious line at the left border of Video Chess now displays
correctly
- All 32 char text demos from AtariAge now work perfectly (Stella 4
shows artifacts on several of these)
- Stella is now the only emulator to display the "Mega Bitmap Demo"
(atext.bin) from AtariAge correctly
- Improved starfield effect for missiles (still TODO for ball and
players)
- RSYNC emulation has improved, all testcases now match real
hardware
- Several other ROMs that have never worked in any emulator are now
emulated correctly
- RDY behavior with respect to write cycles is accurate
- Optional YStart autodetect and more robust frame handling
- NUSIZ during player draw matches hardware
- RESMx during missile draw matches hardware
- Paddle emulation is slightly more accurate. As a consequence, the
"paddle feel" may be slightly different from Stella 4
- Fixed debug colors can now be set for each graphical object, from
a choice of 'red', 'orange', 'yellow', 'green', 'blue' and
'purple'. This is accessible through the new 'tia.dbgcolors'
commandline argument and within the UI.
* Implemented new phosphor emulation mode, which is much closer to real
TV output. Related to this, added ability to change the default
phosphor blend level in the UI and through the new 'tv.phosblend'
commandline argument. Special thanks to Thomas Jentzsch for the idea
and implementation.
* TV phosphor effect can now be force-enabled for all ROMs, instead
of manually setting ROM properties for each ROM. This is accessible
in the UI and through the 'tv.phosphor' commandline argument, and
defaults to being off (or enabled per-ROM).
* PAL color-loss and Blargg TV effects can now be enabled at the same
time. Previously, when Blargg effects were enabled, PAL color-loss
couldn't be shown. Related to this, the Blargg effects now use much
less memory and in some cases run faster than before.
* Much improved RIOT timer emulation never before seen in any emulator.
Special thanks to Christian Speckner (DirtyHairy) for the
implementation, and alex_79 for finding documentation that finally
describes in more detail how the M6532 chip actually works.
* Added BUS (experimental) and CDF bankswitching schemes, and also
ARM Timer 1 support; special thanks to SpiceWare for the code.
* Fixed bug with SaveKey and AtariVox not properly closing their memory
files before starting another instance of the same ROM, when the ROM
was opened in the ROM launcher.
* Various improvements to the debugger and command prompt:
- The 'cls' command now only clears the screen, not the history
- The 'help' command now accepts other commands, and gives extra
information about the command (ie, 'help breakif' prints extended
information about the breakif command)
- Added 'palette' command, which shows a color swatch of the
currently active TIA palette
- Added 'debugcolors' command, which shows a legend for 'fixed debug
colors' mode
- The previous trap'm' commands now work when setting TIA read
addresses; previously they only worked for write addresses
- The previous trap'm' commands are now renamed 'trap', 'trapread'
and 'trapwrite'
- The TIA tab now shows 'old' contents of player and ball registers
- Various UI items are crossed out when disabled, to more clearly
indicate their current state
- Various UI items that previously required a double-click to toggle
(pixel and bit widgets) now require only a single-click.
- Command completion now works with internal functions and pseudo-ops
(basically, anything starting with the '_' character)
- System labels (aka, register names, etc) can now be typed in lower-
case. Previously, these labels always had to be uppercase.
- In general, input error checking is much more strictly enforced
- Read-only UI items now have a different background color, to
clearly indicate if an item can be modified.
- Debugger '.lst' and '.sym' files are now searched based on the name
of the ROM file, and not on the internal properties name.
- Snapshots can now be saved by pressing the F12 key (the various
other ways to save snapshots still exist).
* Mouse grabbing is now enabled in windowed mode only when the ROM is
using a virtual analog controller (paddles, trakball, etc).
* Renamed various trakball-like controllers more accurately: AmigaMouse,
AtariMouse (previously CX80) and Trakball (previously CX22). Related
to this, reduced the resolution of the Trakball by half, to properly
match real hardware.
* The stack pointer (SP) is now initialized to $FD instead of $FF, to
match research done in other 6502 projects.
* Fixed bug in debugger tracing and displaying the partial TIA image;
the first time entering the debugger and starting to trace, the image
was blanked out (black) instead of being drawn in greyscale. Also, the
image is now synchronized, instead of being two frames behind.
* Fixed crash with zipped ROMs that are less than 4K in size; so far
this bug has only ever occurred in Windows XP, but it's been there
since Stella 4.1.
* Fixed bug in 'Rom Audit' functionality; sometimes ROMs without a
valid properties entry were being renamed as "Untitled.bin".
* For the entire UI, removed colons and generally made the UI items
easier to read.
* When in 'ROM launcher mode', Stella now uses slightly less CPU time.
More work is required in this area, though.
* Added ROM properties for D.K. VCS homebrew ROM, thanks to Andreas
Dietrich.
* Added slight improvement for auto-detecting Superchip bankswitching;
the new implementation now works for the NTSC 'Dig Dug' ROM. Special
thanks for SpiceWare for the idea and modified implementation.
* Fixed long-standing bug in 3-voice music in DPC+ bankswitching scheme;
the music now sounds much more like the real thing.
* For the Linux/UNIX port:
- The settings directory now uses the XDG Base Directory Specification.
In most cases, this means that your files will now be stored in
'~/.config/stella' instead of '~/.stella'. To keep your old settings,
run the following commands from the terminal:
cd ~
mv .stella .config/stella
You will probably need to edit '~/.config/stella/stellarc' and change
some paths accordingly.
* For the OSX port:
- Always use the built-in png and zlib libraries instead of the system
versions.
- The preferences file has changed from 'net.sourceforge.Stella.plist'
to 'Stella-emu.plist'. To keep your old settings, run the following
commands from the terminal:
cd ~/Library/Preferences
mv net.sourceforge.Stella.plist Stella-emu.plist
* Updated internal ROM properties database to ROM-Hunter version 13
(thanks go to RomHunter for his tireless research in this area).
Related to this, updated the snapshot collection.
* Updated included PNG and ZLIB libraries to latest stable version. Also,
both libraries are now compiled into the app whenever one is selected.
This fixes issues with a newer ZLIB not working with an older PNG, etc.
* Updated build scripts for Visual Studio 2017 (Windows) and MacOS
Sierra (latest version of Xcode), and make these the minimum supported
versions for building Stella.
* Updated UNIX configure script to work with the clang 5+ and gcc 7+
compiler versions, and fixed compile issues on AArch64 and ppc64le
architectures.

v0.9.0:
This is a major release with several substantial and long-desired new features. There are also updates/modifications to the themes and color palettes that give better consistency with matplotlib 2.0 and some notable API changes.
PyMC3 3.7 (May 29 2019)
New features
Add data container class (Data) that wraps the theano SharedVariable class and let the model be aware of its inputs and outputs.
Add function set_data to update variables defined as Data.
Mixture now supports mixtures of multidimensional probability distributions, not just lists of 1D distributions.
GLM.from_formula and LinearComponent.from_formula can extract variables from the calling scope. Customizable via the new eval_env argument.
Added the distributions.shape_utils module with functions used to help broadcast samples drawn from distributions using the size keyword argument.
Used numpy.vectorize in distributions.distribution._compile_theano_function. This enables sample_prior_predictive and sample_posterior_predictive to ask for tuples of samples instead of just integers.
Maintenance
All occurances of sd as a parameter name have been renamed to sigma. sd will continue to function for backwards compatibility.
HamiltonianMC was ignoring certain arguments like target_accept, and not using the custom step size jitter function with expectation 1.
Made BrokenPipeError for parallel sampling more verbose on Windows.
Added the broadcast_distribution_samples function that helps broadcasting arrays of drawn samples, taking into account the requested size and the inferred distribution shape. This sometimes is needed by distributions that call several rvs separately within their random method, such as the ZeroInflatedPoisson.
The Wald, Kumaraswamy, LogNormal, Pareto, Cauchy, HalfCauchy, Weibull and ExGaussian distributions random method used a hidden _random function that was written with scalars in mind. This could potentially lead to artificial correlations between random draws. Added shape guards and broadcasting of the distribution samples to prevent this.
Added a fix to allow the imputation of single missing values of observed data, which previously would fail.
The draw_values function was too permissive with what could be grabbed from inside point, which lead to an error when sampling posterior predictives of variables that depended on shared variables that had changed their shape after pm.sample() had been called.
draw_values now adds the theano graph descendants of TensorConstant or SharedVariables to the named relationship nodes stack, only if these descendants are ObservedRV or MultiObservedRV instances.
Fixed bug in broadcast_distrution_samples, which did not handle correctly cases in which some samples did not have the size tuple prepended.
Changed MvNormal.random's usage of tensordot for Cholesky encoded covariances. This lead to wrong axis broadcasting and seemed to be the cause for issue 3343.
Fixed defect in Mixture.random when multidimensional mixtures were involved. The mixture component was not preserved across all the elements of the dimensions of the mixture. This meant that the correlations across elements within a given draw of the mixture were partly broken.
Restructured Mixture.random to allow better use of vectorized calls to comp_dists.random.
Added tests for mixtures of multidimensional distributions to the test suite.
Fixed incorrect usage of broadcast_distribution_samples in DiscreteWeibull.
Mixture's default dtype is now determined by theano.config.floatX.
dist_math.random_choice now handles nd-arrays of category probabilities, and also handles sizes that are not None. Also removed unused k kwarg from dist_math.random_choice.
Changed Categorical.mode to preserve all the dimensions of p except the last one, which encodes each category's probability.
Changed initialization of Categorical.p. p is now normalized to sum to 1 inside logp and random, but not during initialization. This could hide negative values supplied to p as mentioned in 2082.
Categorical now accepts elements of p equal to 0. logp will return -inf if there are values that index to the zero probability categories.
Add sigma, tau, and sd to signature of NormalMixture.
Set default lower and upper values of -inf and inf for pm.distributions.continuous.TruncatedNormal. This avoids errors caused by their previous values of None.
Converted all calls to pm.distributions.bound._ContinuousBounded and pm.distributions.bound._DiscreteBounded to use only and all positional arguments.
Restructured distributions.distribution.generate_samples to use the shape_utils module. This solves issues 3421 and 3147 by using the size aware broadcating functions in shape_utils.
Fixed the Multinomial.random and Multinomial.random_ methods to make them compatible with the new generate_samples function. In the process, a bug of the Multinomial.random_ shape handling was discovered and fixed.
Fixed a defect found in Bound.random where the point dictionary was passed to generate_samples as an arg instead of in not_broadcast_kwargs.
Fixed a defect found in Bound.random_ where total_size could end up as a float64 instead of being an integer if given size=tuple().
Fixed an issue in model_graph that caused construction of the graph of the model for rendering to hang: replaced a search over the powerset of the nodes with a breadth-first search over the nodes.
Removed variable annotations from model_graph but left type hints. This means that we support python>=3.5.4.
Default target_acceptfor HamiltonianMC is now 0.65, as suggested in Beskos et. al. 2010 and Neal 2001.
Fixed bug in draw_values that lead to intermittent errors in python3.5. This happened with some deterministic nodes that were drawn but not added to givens.
Deprecations
nuts_kwargs and step_kwargs have been deprecated in favor of using the standard kwargs to pass optional step method arguments.
SGFS and CSG have been removed. They have been moved to pymc3-experimental.
References to live_plot and corresponding notebooks have been removed.
Function approx_hessian was removed, due to numdifftools becoming incompatible with current scipy. The function was already optional, only available to a user who installed numdifftools separately, and not hit on any common codepaths.
Deprecated vars parameter of sample_posterior_predictive in favor of varnames.
References to live_plot and corresponding notebooks have been removed.
Deprecated vars parameters of sample_posterior_predictive and sample_prior_predictive in favor of var_names. At least for the latter, this is more accurate, since the vars parameter actually took names.

What’s New in 0.24.0
This is a major release from 0.23.4 and includes a number of API changes, new features, enhancements, and performance improvements along with a large number of bug fixes.
Highlights include:
* Optional Integer NA Support
* New APIs for accessing the array backing a Series or Index
* A new top-level method for creating arrays
* Store Interval and Period data in a Series or DataFrame
* Support for joining on two MultiIndexes
pkgsrc changes:
- remove patch for totoridipjp (removed in upstream too)
- remove patch for upstream ticket #1323 (integrated in 3.9)
Upstream changes (from "new features of mikutter 3.9"):
* Mastodon plugin
* Support for UI scaling
* World account can be assigned to shortcut key
* Reorder World accounts
* Non-PNG image support for Skin
* Generic Model viewer
* Quick Step
* PulseAudio
* Reorgenize gem dependencies
Upstream pull request log:
https://github.com/twitter/twitter-text/pull/265
* New v3.json config file with emojiParsingEnabled config option. When
true, twitter-text will parse and discount emoji supported by the
twemoji library (see https://github.com/twitter/twemoji). The length
of these emoji will be the default weight (200 or two characters) even
if they contain multiple code points combined by zero-width
joiners. This means that emoji with skin tone and gender modifiers no
longer count as more characters than those without such modifiers.
All 4 implementations updated to reflect this change in counting.
* Updates known gTLDs to recognize recent additions by IANA (#261)
