45\chapter{ANUGA release information}
46
47This document outlines major bug fixes and new functionality added to ANUGA between releases.
48These lists are not comprehensive and we refer to the TRAC system for a complete audit trail of changes made to ANUGA.
49\begin{itemize} 
50    \item Timeline of all changes to the code base: \url{https://datamining.anu.edu.au/anuga/timeline}
51    \item List of completed tasks ordered by last modification time\footnote{Last time a closed ticket was modified will normally correspond to the time it was resolved. However, it is possible that it could be modified after being closed. Refer to the ticket change history if in doubt.}: \url{https://datamining.anu.edu.au/anuga/report/17}
52    \item Changesets between two releases: To see all changes between version 4669 and 4733, for example, visit:
53    \begin{itemize} 
54      \item \url{https://datamining.anu.edu.au/anuga/changeset/4669} through to
55      \item \url{https://datamining.anu.edu.au/anuga/changeset/4733}
56    \end{itemize}   
57\end{itemize}     
58
59The release names take the form
60\begin{verbatim}
61  XX-YY_ZZ.EXT
62\end{verbatim}
63where
64\begin{itemize}
65  \item \code{XX} is the name of the anuga component, e.g.
66  \code{anuga}, \code{anuga\_viewer}, \code{anuga\_installation\_guide} or \code{anuga\_user\_manual}
67  \item \code{YY} is the name of the major revision, e.g. 1.0beta, which is unlikely to change very often unless the code has undergone a major change.
68  \item \code{ZZ} is the Subversion revision number of this release. Every change to ANUGA causes the revision number to increment so this number uniquely identifies the version of ANUA. This is also known as the changeset number.
69  \item \code{EXT} is the file name extension \code{tgz}\footnote{Internet explorer has the habit of renaming the .tgz files to .gz - the remedy is to rename them back or use another browser such as Firefox.} used for source code or \code{pdf} used for documentation.

75\chapter{Release notes}
76
77This chapter list main developments between releases. Small bug fixes,
78refactoring, documentation updates, style fixes are generally not reported
79here. Refer to the Subversion
80log (https://datamining.anu.edu.au/anuga/timeline) and closed tickets
81https://datamining.anu.edu.au/anuga/report/17) for all changes in ANUGA.

83\section{Bleeding Edge}
84
85Work on parallel ANUGA, Kinematic Viscosity, 1-D pipeflows and wind/pressure
86forcing terms. There is also activity in the area of viewers and installers.
87
88
89\section{Release Name: anuga-1.1beta\_7607, Date: 12 January 2010}
90Discarded obsolete variable 'z' in sww files. This commits ANUGA to the
91new viewer: \url{http://www.ausposdevelop.com.au/trac/anuga_viewer}.
92Small optimisations and cleaning
93Intoduced one-click Windows installer
94Updates on the parallel code.
95
96\section{Release Name: anuga-1.1beta\_7472, Date: 3 September 2009}
97
98Ability to store any quantity in the sww file either as static or
99time dependent. This allows for example storage of variable bed elevation
100and/or friction. See manual for details on set\_quantities\_to\_be\_stored.
101
102
103\section{Release Name: anuga-1.1beta\_7315, Date: 20 July 2009}
104
105ANUGA updated to work with Python 2.6
106Reference to new viewer in manual.
107
108
109
110\section{Release Name: anuga-1.1beta\_7302, Date: 6 July 2009}
111This is the first release of ANUGA based on the package Python-numpy.
112The reason for this upgrade is that the old package Numeric is
113no longer supported and doesn't work for some systems.
114See the installation guide for details regarding the new dependencies.
115
116
117\section{Release Name: anuga-1.0beta\_7163, Date: 9 June 2009}
118
119THIS IS THE LAST OFFICIAL RELEASE OF ANUGA BASED ON THE PYTHON NUMERIC PACKAGE.
120
121\begin{itemize}
122  \item Several optimisations. ANUGA now runs at least 10-15\% faster overall. See changesets 7143, 7136, 7105, 7034, 6840, 6737, 6703.
123  \item Culverts based on the Boyd method have been refactored and test suite added thanks to Rudy van Drie and Petar Milevski.
124  \item Added a special purpose boundary (AWI boundary) provide by Nils Goseberg.
125  \item Cleanup Cairns demo and introduced example of new method add\_quantity.
126\end{itemize}
127

129
130\section{Release Name: anuga-1.0beta\_6838, Date: 19 April 2009}
131\begin{itemize}
132  \item Implemented availability of average energy as well as flow
133  through cross-section at run-time (ticket:295)
134  \item Stored permutation from urs2sts in STS file (ticket:298)
135  \item Equipped File\_boundary and Field\_boundary with default boundary
136  conditions to allow modelling beyond time interval (ticket:293)
137  \item Allowed fitting to reuse ANUGA mesh saving memory and time.
138  \item Started new module anuga.interface containing common functions. In particular the new function create\_domain\_from\_regions (ticket:308 and changeset:6190) which can replace the old call to create\_mesh\_from\_regions followed by Domain. This not only simplifies domain creation, it also makes caching of this process water proof. This function has not yet been documented in the user manual.
139  \item Made evolve loop about 5\% faster due to optimisations in
140  changeset:6703 and changeset:6737.
141  \item Fixed tests that only failed on Windows.
142\end{itemize} 
143
144
145\section{Release Name: anuga-1.0beta\_5638, Date: 11 August 2008}
146
147\begin{itemize}
148  \item Better diagnostics for timestepping.
149  \item Implemented tracking of IP for data files bundled with ANUGA to ensure that all are legally OK to distribute.
150  \item Improved logging of model runs (screen_catcher and copy_code_files).
151  \item Refactored graphing of timeseries into extraction and plotting (see sww2timeseries and sww2cvs\_gauges).
152  \item Improved performance and memory management in generate mesh and  least squares fitting.
153  \item Simplified Quantity data structure.
154  \item Added more validation examples.
155  \item Function for automatically determining optimal smoothing parameter through cross validation (\code{get\_flow\_through\_cross\_section}, p 57 in the user manual)
156  \item Implemented better second order approximation through the option to use edge limiters along with second order Runge-Kutta timestepping.
157        This provides better accuracy in some cases (e.g. waves in deep water over long distances)
158  \item Made tight\_slope\_limiters the default.
159  \item Retired obsolete parameter beta_h
160  \item Added the Okada tsunami source model as an optional initial condition in ANUGA
161  \item Upgraded ANUGA to work with Python 2.5
162  \item New fileboundary (using NetCDF format with extension .sts) coupling for timeseries on a list of points.
163  \item Added new forcing terms for flood modelling capability: Rainfall, Inflow, Culverts, ... (See p 51-53)
164\end{itemize}   
165 
166 
167\section{Release Name: anuga-1.0beta\_4824, Date: 15 Nov 2007}
168
169\begin{itemize} 
170  \item Removal of obsolete Python code where (faster) C code exists.
171  \item Several updates in the documentation in response to postings.
172  \item Improved installation and compilation procedure.
173  \item Addressed excessive memory use in fitting (currently optional as it appears somewhat slower)
174\end{itemize} 
175
176
177\section{Release Name: anuga-1.0beta_4733, Date 12 Sep 2007}
178
179\begin{itemize} 
180  \item A number of optimisations making the evolution part of ANUGA about 40\% faster. See \url{https://datamining.anu.edu.au/anuga/ticket/135} for details.
181  The optimisations are
182  \begin{itemize} 
183     \item Dry cell exclusion from flux calculations and linear reconstruction of triangles.
184     This optimisation will be most effective in domains with large dry areas. 
185     \item Separation of functions into gateways and computational routines
186     \item Utilisation of static work arrays
187     \item A large number of minor optimisations
188  \end{itemize} 
189 
190  \item Obsolete code was cleared out.
191\end{itemize}   
192

206
207\begin{itemize} 
208  \item First public release of ANUGA - Hydrodynamic Modelling.
209\end{itemize} 
210Version 1.0beta is the first version for general use. It is considered as a beta release as we expect feedback and suggestions for improvement by the community.
211
212The minor release number (4106) is the revision number from Subversion and uniquely defines the exact version of ANUGA.
