Current News Jan 13, 2003 Better late than never! OPP 0.3 development is now open. Version 0.3 was originally intended to be an interim release that implemented a new public interface that would enable the addition of substantial new functionality in future releases. However, due largely to outside events that have delayed implementation but allowed high level design to proceed; the original schedule has been revised and the feature set for 0.3 has been extended. Version 0.3 features a new public interface with a defined standard; transparent persistence; a redesigned and optimized embedded object database; a vastly improved I/O, socket and internet architecturel; improved thread support and many other enhancements. Much work remains to complete 0.3 for release. However; thanks to an improved test suite, it already exceeds 0.2.5 in stability in many ways. Read the development page for more information; including important caveats to 0.3. Oct 14, 2000 OPP 0.2.5 is released: opp-0.2.5.tar.gz (~437K). We haven't had enough time to work on version 0.3, so it is lagging terribly. This release fixes some bugs in OPP 0.2 and includes some new features that were intended for 0.3. It's been pretty well tested, but some last minute changes also made it in so there may be bugs lurking. See CHANGES for a summary of changes made to each version of OPP. In 0.2.5: HTML parser that can interpret HTML as a human reader can, understanding tables, fonts and so on. It can also "fix" broken HTML. This is a proof of concept implementation, with better and more compliant versions to come. Enhanced thread support including RecursiveMutex, SpinLock, PCQueue (template message queue) and ThreadPool. Internet address classes (InetAddress, InetHost, InetPort, URL). Client and server side support for HTTP Cookies. Abstracted URL retrieval incorporating the HTTP class along with the new File and FTP classes. Name and abbreviation matching algorithm.

StatusStatus from January 13, 2003OPP 0.3 is now publicly available for development purposes. The Template, Database, IO and System packages have been mostthoroughly tested. The Base, Net and Thread packages has been reasonably well tested. Utility, Collection, Parser and Documenthave not yet been tested. Utility and Parser shouldn't have a lot of bugs as they have not been changed too much. Collection andDocument are likely to not work. Not all functionality scheduled for OPP 0.3 has been completed yet. See thedevelopment page for more details.

Old News Jan 30, 2000 Work on OPP has been delayed because of other work commitments. Jul 18, 1999 New look and content for the website. I've decided to add transparent persistent storage to the collection classes for version 0.3. As a result, the 0.3 release date is going to be pushed back a couple of weeks. It's the right time to add this feature, since I was already rewriting all the collection classes for allocators and iterators. Jun 23, 1999 Features coming in OPP 0.3: Portable to multiple UNIX platforms (at least Linux and Solaris). HTML parser that can interpret HTML as a human reader can, understanding tables, fonts and so on. It can also "fix" broken HTML. Version 0.3 should be considered a proof of concept implementation, with better and more compliant versions to come. Enhanced thread support including RecursiveMutex, SpinLock, PCQueue (template message queue) and ThreadPool. Internet address classes (InetAddress, InetHost, InetPort, URL). Client and server side support for HTTP Cookies. Java and Standard C++ Library style interfaces to OPP classes. Object database performance enhancements. Iterator and allocator support in OPP collection classes. New template collections for Vectors and Heaps. Documentation Standardized interface (common naming conventions, standard methods for common functionality, etc.) May include rearchitected Strings with enhanced functionality and usability. Mar 13, 1999 OPP Version 0.2 is now available.Brave souls willing to risk vile bugs, hideous misfeatures and an architecture and interface that may change daily can downloadopp-0.2.tar.gz (~242K). OPP Version 0.2 requires Linux and GNU make andis known to work with egcs version 2.91.60 (aka 2.1.1). It is believed that OPP requires a recent version of egcs in order tocompile (egcs 1.0.3 is known to have bugs that prevent OPP from compiling and/or working correctly).Version 0.2 adds many bug fixes, enhanced parsing, HTTP and EMail. Read CHANGES for the complete set of changes. Jan 3, 1999 OPP Version 0.1a is now available. Version 0.1a is mostly a bug fix release of OPP version 0.1. Besides bug fixes, version 0.1a includes a class for date and time parsing. Read CHANGES for the complete set of changes. Dec 30, 1998 Announcing the first public release of OPP. OPP Version 0.1 has template and object rooted collection classes and a variety of string, I/O, network and thread classes.OPP aims to provide: An object oriented framework for cross-platform applicationdevelopment. The functionality found in the Rogue Wave class libraries;especially Tools.h++, Threads.h++ and the network classes now part ofNet.h++ An interface familiar to Java programmers and suitable for easyporting of Java code to C++. A multithreaded embedded Object Database and correspondingdatabase server. An object oriented container framework. This functionalityoverlaps with the capabilities of the standard C++ library, butfollows a decidedly different philosophy.The 0.1 release of OPP fails to meet any of thesegoals in a meaningful way. It does work, and Odin Properties isusing it to develop the next generation of Web Portal software, asused by the Index of Alternative Operating Systems.
