What's new in this version:

- QuickStart Pack: Now offers to download and install Inno Script Studio besides InnoIDE.
- Setup now only allows the "Don't create a Start Menu folder" check box to suppress the creation of shortcuts under {group}. Previously, it would also suppress the creation of shortcuts in other locations, such as {userstartup}, on entries that lacked a Tasks parameter.
- Setup now doesn't count files with Tasks/Check parameters when calculating the disk space shown at the bottom of the Select Components page.
- Improved throughput of external file copying on some devices.
- On Unicode, Setup now supports Rich Edit 4.1 when available.
- Inno Setup Preprocessor (ISPP) changes:
- Documentation improvements: Added the functions available from ISPPBuiltins.iss to the help file.
- #ifexist/#ifnexist: For consistency with ISPP functions, prepend SourcePath if the filename is relative, and also support prefix expansion.
- ReadReg: Now only requests KEY_QUERY_VALUE access on the key. Previously, it requested KEY_ALL_ACCESS.
- The Inno Setup source code is now also available as a Git repository at GitHub. This should make it easier to contribute to Inno Setup, see GitHub Help - Fork A Repo for more info.
- Added official Serbian (both Latin and Cyrillic) and Ukrainian translations.
- Minor tweaks.
