version 1.5.2:
(THIS VERSION IS IN DEVEL AND CAN BE CHANGED AT ANY TIME)
- improve description of inbetween warmup and contest in ADMIN.txt
- fix a bug that could allow an user to change their username
- creation of an APACHE.txt doc about setting up apache configuration
- force source files to have no spaces (warn a message in case they have)
version 1.5.1:
2012/10/20:
- (ICPC Linux) fixed logging in issue after cleandisk.sh
- (ICPC Linux) inclusion of some (new) suggested packages and links
- updated safeexec (there was a timing issue between time-limit and run-time-error)
- updated installboca.sh to account for different install directories
- fix bug with the option that teams can't change their password. This was causing login problems.
version 1.5.0:
2012/08/24
- (ICPC Linux) updated scripts to create ICPC linux under ubuntu
12.04. Hopefully it will still work with older versions of ubuntu.
- (ICPC Linux) java version now is openjdk6 (it is getting harder to
keep using sun java on new linux distributions)
- Problems in BOCA are now defined by a problem package in ZIP format,
which can be encrypted.
- private/score.sep file now allows also the specification of by-user
and by-site scoretables.
- admin password need to change other users' passwords.
- option to import users using the ICPC webpage formats (.tab and .tsv).
- multi-site re-included in the system, with a centralized idea (one
main server and many local servers that connect to it). The
connection is done (encryptedly) via http and is handled by a new type of
user named type "site".
- main site can provide redundancy in case of failure, as it has a
copy of everything.
- autojudging scheme has been improved, specially in terms of
safety. Scripts to judge are now inside the problem package.
- examples of problem packages are included in doc/problemexamples/
- option to delete and undelete problems included, so one can setup
the warmup and contest with all problems, delete some, undelete later.
- bug fix in updating time of contest and sites (updating contest
didn't update sites).
- options to insert keys and password in the tab contest in order to
unlock problems in case they are encrypted.
- documentation files updated.
version 1.4.2:
2011/11/04
- user type site created to allow for pushing of scores from other sites
- createdb.php moved to private/ for better safety. Option to abort its execution is included.
- autojudging.php moved to private/ for better safety
- possibility of multiple scores defined by the private/score.sep file
- fix of setup.sh and rc.local scripts to properly set firewall rules (thanks Flavio GC Rocha).
Also some other minor script changes, such as /etc/network/if-pre-up.d/boca
- script that creates the bocajail changed to /etc/icpc/createbocajail.sh and some
improvements are applied (e.g. use of debootstrap). It should now run smoother on
ubuntu and other debian-like systems.
- bugfix: general clarification option was not appearing in the list of problems.
- scripts have been updated to make it easy to replace the use of user 'www-data' by 'apache'.
- updatescores.sh now accepts full path names for servers. This solves the case where boca
is not installed in the default http://SERVER/boca/
- updatescores.sh now gets all the available information about the score of the other sites, and
the local boca server decides which info shall be put in the score board. This fixes issues with
displaying undesired info from other sites, because the responsability is given to local boca.
- webcast directory for F. D. Moreira's fancy score included in the distro.
version 1.4.1:
2011/10/10

judged by two judges. In case of disagreement, chief judge or admin has to act.
- new feature: judges can submit code to the system (even before the competition is running).
- new feature: admin and chief judge can open multiple runs to re-judge at once in the same screen.
- scripts to run code at doc/bits/ updated to cope with new safeexec and possible chrooting

judged results, while the runs are rejudged. If a change is performed, then the new status is seen.
- autojudging procedure now keeps a copy of input and output files in the local filesystem, so the
network and DB accesses are reduced (Thanks to huge files of Wanderley Guimaraes :).

do not know if this was a bug or a feature.
