ChangeLog for 3.20.1 (v3-stable)

Version 3.20.1 [v3-stable] (rgerhards), 2008-112-04

• security bugfix: $AllowedSender was not honoured, all senders were
  permitted instead (see security advisory)

• enhance: regex nomatch option “ZERO” has been added
  This allows to return the string 0 if a regular expression is
  not found. This is probably useful for storing numerical values into
  database columns.

• bugfix: memory leak in gtls netstream driver fixed
  memory was lost each time a TLS session was torn down. This could
  result in a considerable memory leak if it happened quite frequently
  (potential system crash condition)

• doc update: documented how to specify multiple property replacer
  options + link to new online regex generator tool added

• minor bufgfix: very small memory leak in gtls netstream driver
  around a handful of bytes (< 20) for each HUP
• improved debug output for regular expressions inside property replacer
  RE’s seem to be a big trouble spot and I would like to have more
  information inside the debug log. So I decided to add some additional
  debug strings permanently.
