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}

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.

88\section{Release Name: anuga-1.0beta\_7163, Date: 9 June 2009}
89
90\begin{itemize}
91  \item Several optimisations. ANUGA now runs at least 10-15\% faster overall. See changesets 7143, 7136, 7105, 7034, 6840, 6737, 6703.
92  \item Culverts based on the Boyd method have been refactored and test suite added thanks to Rudy van Drie and Petar Milevski.
93  \item Added a special purpose boundary (AWI boundary) provide by Nils Goseberg.
94  \item Cleanup Cairns demo and introduced example of new method add\_quantity.
95\end{itemize}

99\section{Release Name: anuga-1.0beta\_6838, Date: 19 April 2009}
100\begin{itemize}
101  \item Implemented availability of average energy as well as flow
102  through cross-section at run-time (ticket:295)
103  \item Stored permutation from urs2sts in STS file (ticket:298)
104  \item Equipped File\_boundary and Field\_boundary with default boundary
105  conditions to allow modelling beyond time interval (ticket:293)
106  \item Allowed fitting to reuse ANUGA mesh saving memory and time.
107  \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.
108  \item Made evolve loop about 5\% faster due to optimisations in
109  changeset:6703 and changeset:6737.
110  \item Fixed tests that only failed on Windows.
111\end{itemize} 
112
113
114\section{Release Name: anuga-1.0beta\_5638, Date: 11 August 2008}
115
116\begin{itemize}
117  \item Better diagnostics for timestepping.
118  \item Implemented tracking of IP for data files bundled with ANUGA to ensure that all are legally OK to distribute.
119  \item Improved logging of model runs (screen_catcher and copy_code_files).
120  \item Refactored graphing of timeseries into extraction and plotting (see sww2timeseries and sww2cvs\_gauges).
121  \item Improved performance and memory management in generate mesh and  least squares fitting.
122  \item Simplified Quantity data structure.
123  \item Added more validation examples.
124  \item Function for automatically determining optimal smoothing parameter through cross validation (\code{get\_flow\_through\_cross\_section}, p 57 in the user manual)
125  \item Implemented better second order approximation through the option to use edge limiters along with second order Runge-Kutta timestepping.
126        This provides better accuracy in some cases (e.g. waves in deep water over long distances)
127  \item Made tight\_slope\_limiters the default.
128  \item Retired obsolete parameter beta_h
129  \item Added the Okada tsunami source model as an optional initial condition in ANUGA
130  \item Upgraded ANUGA to work with Python 2.5
131  \item New fileboundary (using NetCDF format with extension .sts) coupling for timeseries on a list of points.
132  \item Added new forcing terms for flood modelling capability: Rainfall, Inflow, Culverts, ... (See p 51-53)
133\end{itemize}   
134 
135 
136\section{Release Name: anuga-1.0beta\_4824, Date: 15 Nov 2007}
137
138\begin{itemize} 
139  \item Removal of obsolete Python code where (faster) C code exists.
140  \item Several updates in the documentation in response to postings.
141  \item Improved installation and compilation procedure.
142  \item Addressed excessive memory use in fitting (currently optional as it appears somewhat slower)
143\end{itemize} 
144
145
146\section{Release Name: anuga-1.0beta_4733, Date 12 Sep 2007}
147
148\begin{itemize} 
149  \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.
150  The optimisations are
151  \begin{itemize} 
152     \item Dry cell exclusion from flux calculations and linear reconstruction of triangles.
153     This optimisation will be most effective in domains with large dry areas. 
154     \item Separation of functions into gateways and computational routines
155     \item Utilisation of static work arrays
156     \item A large number of minor optimisations
157  \end{itemize} 
158 
159  \item Obsolete code was cleared out.
160\end{itemize}   
161
162
163\section{Release Name: anuga-1.0beta_4669, Date 17 Aug 2007}
164\begin{itemize} 
165  \item Improved speed in set\_quantity
166  \item deprecated xya file format
167  \item general maintenance
168\end{itemize}   
169 
170\section{Release Name: anuga-1.0beta_4530, 4 June 2007}

173
174\section{Release Name: anuga_1.0beta_4106, 20 Dec 2006}
175
176\begin{itemize} 
177  \item First public release of ANUGA - Hydrodynamic Modelling.
178\end{itemize} 
179Version 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.
180
181The minor release number (4106) is the revision number from Subversion and uniquely defines the exact version of ANUGA.
