-----------------------------------
(In following lines from Changelog, marked as | are the same as in 0.11rc2)
0.11 (2013-05-25)

| Changes by Wojtek Kaniewski <wojtekka@toxygen.net>:
| - changed license to GPL version 2. There was no license information before
|  which caused confusion. Code by Tomasz Lipski <lemur@irc.pl> and awayzzz
|  <awayzzz@digibel.org> had to be removed, because their e-mail addresses
|  were dead and googling for them gave no useful information. The missing
|  features have been rewritten from scratch. If any offending code is still
|  here, please let me know. I've done my best, but I haven't used any
    version control 5 years ago,
  - changed e-mail address,
  - ignore IPv4/IPv6 address hints when option -H is present.

| Changes by Ramunas Lukosevicius <lukoramu@parok.lt>
| - fixed source mapping bug,
| - SIGHUP reloads map file.

  Changes by Roland Stigge <stigge@antcom.de>
  - fix an error in the "hints" handling of the host resolver which confused
    local/source and remote hint (AF_INET/AF_INET6).

  Changes by Olaf Rempel <razzor@kopf-tisch.de>
  - correct option -f.

  (note: -H option is added, -r option is converted to -f)
(pkgsrc changes)
- Add LICENSE as gnu-gpl-v2
