1.1.5
  - Fixes for machine-readable indices. Key expiration times are now read
    from self-signatures on the key's UIDs. In addition, instead of 8-digit
    key IDs, index entries now return the most specific key ID possible:
    16-digit key ID for V3 keys, and the full fingerprint for V4 keys.
  - Add metadata information (number of keys, number of files, 
    checksums, etc) to key dump. This allows for information on the
    key dump ahead of download/import, and direct verification of checksums
    using md5sum -c <metadata-file>.  
  - Replaced occurrances of the deprecated operator 'or' with '||' (BB issue #2)
  - Upgraded to cryptlib-1.7 and own changes are now packaged as separate 
    patches that is installed during 'make'. Added the SHA-3 algorithm, Keccak
  - Option max_matches was setting max_internal_matches. Fixed (BB issue #4)
  - op=hget now supports option=mr for completeness (BB issue #17)
  - Add CORS header to web server responses. Allows JavaScript code to
    interact with keyservers, for example the OpenPGP.js project.
  - Change the default hkp_address and recon_address to making the 
    default configuration support IPv6. (Requires OCaml 3.11.0 or newer)
  - Only use '-warn-error A' if the source is marked as development as per
    the version suffix (+) (part of BB Issue #2)
  - Reduce logging verbosity for debug level lower than 6 for (i) bad requests, 
    and (ii) no results found (removal of HTTP headers in log) (BB Issue #13)
  - Add additional OIDs for ECC RFC6637 style implementations
    (brainpool and secp256k1) (BB Issue #25) and fix issue for 32 bit arches.
  - Fix a non-persistent cross-site scripting possibility resulting from 
    improper input sanitation before writing to client. (BB Issue #26 | CVE-2014-3207)

1.1.4
  - Fix X-HKP-Results-Count so that limit=0 returns no results, but include
    the header, to let a client poll for how many results exist, without
    retrieving any. Submitted by Phil Pennock. See:
    http://lists.nongnu.org/archive/html/sks-devel/2010-11/msg00015.html
  - Add UPGRADING document to explain upgrading Berkeley DB without
    rebuilding. System bdb versions often change with new SKS releases
    for .deb and .rpm distros.
  - Cleanup build errors for bdb/bdb_stubs.c. Patch from Mike Doty
  - Update cryptokit from version 1.0 to 1.5 without requiring OASIS
    build system or other additional dependencies
  - build, fastbuild, & pbuild fixed to ignore signals USR1 and USR2
  - common.ml and reconSC.ml were using different values for minumimum
    compatible version. This has been fixed.
  - Added new server mime-types, and trying another default document (Issue 6)
    In addition to the new MIME types added in 1.1.[23], the server now
    looks over a list and and serves the first index file that it finds
    Current list: index.html, index.htm, index.xhtml, index.xhtm, index.xml.
  - options=mr now works on get as well as (v)index operations. This is
    described in http://tools.ietf.org/html/draft-shaw-openpgp-hkp-00
    sections 3.2.1.1. and 5.1.
  - Updated copyright notices in source files
  - Added sksclient tool, similar to old pksclient
  - Add no-cache instructions to HTTP response (in order for reverse proxies
    not to cache the output from SKS)
  - Use unique timestamps for keydb to reduce occurrances of Ptree corruption.
  - Added Interface specifications (.mli files) for modules that were missing
    them
  - Yaron pruned some no longer needed source files from the tree.
  - Improved the HTTP status and HTTP error codes returned for various
    situations and added checks for more error conditions.
  - Add a suffix to version (+) indicating non-release or development builds
  - Add an option to specify the contact details of the server administrator
    that shows in the status page of the server. The information is in the
    form of an OpenPGP KeyID and set by server_contact: in sksconf
  - Add a `sks version` command to provide information on the setup.
  - Added configuration settings for the remaining database table files. If
    no pagesize settings are in sksconf, SKS will use 2048 bytes for key
    and 512 for ptree. The remainining files' pagesize will be set by BDB
    based on the filesystem settings, typically this is 4096 bytes.
    See sampleConfig/sksconf.typical for settings recommended by db_tuner.
  - Makefile: Added distclean target. Dropped autogenerated file from VCS.
  - Allow tuning BDB environment before creation in [fast]build and pbuild.
    If DB_CONFIG exists in basedir, copy it to DB dir before DB creation.
    Preference is given to DB_CONFIG.KDB and DB_CONFIG.PTree over DB_CONFIG.
  - Add support for Elliptic Curve Public keys (ECDSA, ECDH)
  - Add check if an upload is a revocation certificate, and if it is, 
    produce an error message tailored for this.
  
1.1.3
  - Makefile fix for 'make dep' if .depend does not exist. Issue #4
  - Makefile fix: sks and sks_add_mail fail to link w/o '-ccopt -pg'
    Issue #23
  - Added -disable_mailsync and -disable_log_diffs to sks.pod
  - Added file extensions .css, .jpeg, .htm, .es, .js, .xml, .shtml, .xhtm,
    .xhtml and associated MIME types to server code. Part of Issue #6
  - Added sample configuration files in sampleConfig directory
  - Added sample web page files in sampleWeb directory. Issues #7, 9, 19
  - Allow requests for non-official options hget, hash, status, & clean to
    be preceded by '-x'. Closes issues #10, 11, 13, & 14.
  - Allow &search with long subkey ID (16 digit) and subkey fingerprint
    subkey lookup was failing with other than a short key ID. However,
    public key lookup was working with short and long key ID and fingerprints.
    This patch makes subkey lookup behave the same as full key lookup.

  - SKS can be configured to listen to two ports for HKP access.

1.0.3: added simple built-in webserver so that index page can be served by
       sks_db.  This should make it easier to put sks on port 80.  Also,
       sks can now be launched from any directory, as long as the -basedir
       command-line option is used to specify the location of the sks
       directory.

1.0.2: Serious database corruption bug in fastbuild and build fixed.  Also,
       client.ml modified to avoid Yet Another Deadlock Bug.
