scilab (6.1.1+dfsg2-8) unstable; urgency=medium

  Due to the upcoming removal from Debian of the former library for regular
  expressions handling, we had to transition scilab to pcre2, which has been
  the new reference for years, in order to keep support for regular expressions
  in scilab.

  Still, there are some changes one needs to notice:
  - Delimiters at the start and the end of patterns must not be written. For
    instance, the former "/pattern/" pattern must now be written "pattern";
  - Also it is no more possible to provide modifiers "i", "m" nor "x", which
    previously allowed one to respectively perform case-insensitive matches,
    multiline matches or matches with comments in the patterns. For instance,
    one can no longer use "/pattern/i" to match "pattern", "PATTERN",
    "PatteRn", ...

  The affected scilab functions are csvRead, grep, regexp, strindex, strsubst.
  The explanations and examples in their help pages have been updated
  accordingly.
