SecureSkat 2.14:
- reflect API changes from LibTMCG
- bugfix: include libintl in the library path when building executables
SecureSkat 2.13:
- bugfix: reduce length of unique game IDs due to restrictive IRC limits
SecureSkat 2.12:
- configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.19.8.
- bugfix: removed wrong CloseHandle() in the ballot capability
- introducing environment variable ALTHOST to set an alternative hostname
- increased bit length for generated TMCG/Rabin keys to 2048 bit
- SecureSkat_random: randomize playing of allowed cards during game
- replaced random() by LibTMCG's function mpz_wrandom_ui()
- added configure switch --with-gdbm=<path> for non-standard search path
SecureSkat 2.11:
- minor bugfixes and a check for new LibTMCG 1.3.2 have been added
SecureSkat 2.10:
- permit changing a vote by using /<room> vote <value> multiple times
- call version_LibTMCG() to display the version of LibTMCG upon startup
- check for LibTMCG 1.3.1: using the improved security parameters
- bugfix: bad IRC username was constructed, if keyid contains 'Z'
- use SetupGenerators_*() in VSSHE to protect agains malicious provers
SecureSkat 2.9:
- massive code cleanup
- removed obsolete GnuTLS dependency
- bugfix ranking statistics (command /rank); bug was introduced in 2.8
SecureSkat 2.8:
- added a message delay to avoid kick off (e.g. irc.freenode.net)
- removed obsolete stuff (ABHEBEN, COMMON_DDH_GROUP, old PBKDF)
- increased iteration count of PBKDF1 to 7000 (key file encryption)
- key identifier has now only 5 characters (RFC: nick length 9 chars)
- using non-NIZK keys (need LibTMCG 1.1.0) for faster key generation
- removed obsolete command line argument SECURITY_LEVEL (default=80)
SecureSkat 2.7:
- we're now using Groth's protocol for the verifiable secret shuffle
(this improves performance and communication complexity significantly)
- Null-games are now aborted immediately, if lost by the playing party
- added an alternative table announcement (PRIVMSG to channel), because
some IRC servers (e.g. freenode.net) are blocking PRIVMSG to users
- the command /players now additionally shows the key fingerprints
SecureSkat 2.6:
- bugfixes and some German translations (internationalization support)
- secret key protection: use the PBKDF1 from RFC 2898 (salt and it.-count)
- user commands for manually public key export and import (file)
- directory ~/.SecureSkat is now used for the key and ranking databases
- changed the COMMON_DDH_GROUP to the well-known MODP group 2 of RFC 2412

SecureSkat 2.5:
- a bug in the generation of the ranking data was fixed
- important bugfixes for the secret voting functions
- protecting the secret key: encryption with user-supplied pass phrase
- a bug in the control program "SecureSkat_random" was fixed
(it occured only, if the player has used a nickname with spaces)
- rudimentary internationalization support (GNU gettext) added
SecureSkat 2.4:
- LibTMCG is now separated from the SecureSkat package
(see http://savannah.nongnu.org/projects/libtmcg/)
- URGENT security fix: our implementation of a proof of knowledge
(equality of discrete logarithms) was not sound, i.e. the missing
instantiation of mpz_shash on the verifier side permits cheating.
These problems are issues of the library LibTMCG. We announce them
here to reach all affected users of LibTMCG resp. SecureSkat.
SecureSkat 2.3:
- initial nonGNU/Savannah release (former name openSkat, included LibTMCG)
