- The default encoding for Erlang source files is now UTF-8. As a temporary measure to ease the transition from the old default of Latin-1, if EDoc encounters byte sequences that are not valid UTF-8 sequences, EDoc will re-try in Latin-1 mode. This workaround will be removed in a future release. - Own Id: OTP-12008 
Syntax_Tools 1.6.15

Syntax_Tools 1.6.7.2
Improvements and New Features
- Variables are now now allowed in ' - fun M:F/A' as suggested by Richard O'Keefe in EEP-23.- The representation of ' - fun M:F/A' in the abstract format has been changed in an incompatible way. Tools that directly read or manipulate the abstract format (such as parse transforms) may need to be updated. The compiler can handle both the new and the old format (i.e. extracting the abstract format from a pre-R15 BEAM file and compiling it using compile:forms/1,2 will work). The- syntax_toolsapplication can also handle both formats.- * POTENTIAL INCOMPATIBILITY * - Own Id: OTP-9643 
- Eliminate use of deprecated regexp module - Own Id: OTP-9810 
Syntax_Tools 1.6.7.1
Fixed Bugs and Malfunctions
