Abbrevia 5.0 is now available.

Abbrevia is a data compression toolkit for Embarcadero Delphi, C++ Builder, and Kylix, and FreePascal. It supports PKZip, Microsoft CAB, tar, gzip, bzip2 and zlib compression formats, and the creation of self-extracting archives. It includes several visual components that simplify displaying archives.

Abbrevia now officially supports FreePascal on Windows, OS X, and Linux, both 32-bit and 64-bit. It includes all changes from "fparchive" and, due to the number of bugs fixed since that release, I strongly recommend anyone using it upgrade. The visual controls and SDK wrappers for LZMA, PPMd, and WavPack are currently Delphi-only, but I'd welcome any assistance to fix that.

This release adds a number of new features and support for more platforms:

* RAD Studio XE2 support, including both 64-bit Windows and OS X
* FreePascal support on Windows, OS X, and Linux
* TAbTreeView and TAbListView VCL controls that provide an Explorer/WinZip-like interface
* ZIP64 support, for archives larger than 2GB
* Improved split/spanned zip support
* Expanded LZMA support
* Unicode filenames in tar and gzip archives

This is a source-only release. It includes design-time and run-time packages for Delphi 6 through Delphi XE2, C++Builder 2009 through XE2, and Kylix 3. FreePascal is supported, but runtime/design time packages are not included. It is licensed under the Mozilla Public License, v1.1.
