paulo@0: Gnutella 0.0.11:
paulo@0: 
paulo@0: 	* Made SHA1 implementation work correctly on 64 bit machines.
paulo@0: 
paulo@0: 	* Create new client GUID on each startup to prevent stupid packagers
paulo@0: 	  from hurting the network.
paulo@0: 
paulo@0: 	* Disable the timebomb once and for all.
paulo@0: 	
paulo@0: Gnutella 0.0.10.1:
paulo@0: 
paulo@0:     * Added additional revision digit to version number so we can release
paulo@0:       packages with updated GT_RELEASE_DATE if nothing else has changed.
paulo@0: 
paulo@0:     * Increased web cache disabling to 365 days after built and complete
paulo@0:       shutdown to 1.5 years.
paulo@0: 
paulo@0: Gnutella 0.0.10:
paulo@0: 
paulo@0:     * Disconnect idle nodes that don't reply to pings.
paulo@0: 
paulo@0:     * Support Vendor Messages.
paulo@0: 
paulo@0:     * Support ConnectBack vendor message for better firewalled status
paulo@0:       detection.
paulo@0: 
paulo@0:     * Slightly improved the random number seed.
paulo@0: 
paulo@0:     * Send an empty error page when the remote side supports queueing.
paulo@0: 
paulo@0:     * All searches now timeout after at most 10 minutes.
paulo@0: 
paulo@0:     * Only use the full http:// URL in GWebcache requests when using a proxy
paulo@0:       (see RFC 2616 (HTTP/1.1) for further information).
paulo@0: 
paulo@0:     * Support outgoing compression of message streams.
paulo@0: 
paulo@0:     * Drop "urn:" trailer from queries sent.
paulo@0: 
paulo@0:     * Send full filename in PUSH uploads; seems LimeWire requires it.
paulo@0: 
paulo@0:     * Support p->share_hide/show for hiding shares from other nodes with
paulo@0:       a HopsFlow message, allowing them to be efficiently un/re-shared.
paulo@0: 
paulo@0:     * Basic support for sending GGEP blocks.
paulo@0: 
paulo@0:     * Change "really-old" auto-deactivation to silent failure to avoid
paulo@0:       creating surprises for people who don't care.
paulo@0: 
paulo@0:     * Support push proxies:  put a GGEP block containing the IP address of
paulo@0:       some servers we're connected to in order to improve upload performance
paulo@0:       of firewalled nodes.
paulo@0: 
paulo@0:     * Ban webcaches that resolve to local IP addresses.
paulo@0: 
paulo@0: Gnutella 0.0.9.2:
paulo@0: 
paulo@0:     * Fix file descriptor leak in file_cache.c that's been around for a while
paulo@0:       but was made worse by syncing the nodes files every so often.
paulo@0: 
paulo@0:     * Don't potentially poll the CPU if the remote zlib stream is called with
paulo@0:       Z_FINISH.
paulo@0: 
paulo@0: Gnutella 0.0.9.1:
paulo@0: 
paulo@0:     * Remove checking for -lresolv in configure.
paulo@0: 
paulo@0: Gnutella 0.0.9:
paulo@0: 
paulo@0:     * Fix compile problem with 0.0.8 on big-endian platforms.
paulo@0: 
paulo@0:     * Deactivate the plugin if it's more than one year old.
paulo@0: 
paulo@0:     * Close all searches when plugin is unloaded.
paulo@0: 
paulo@0: Gnutella 0.0.8:
paulo@0: 
paulo@0:     * Trim the node list every so often to prevent it from growing unbounded.
paulo@0: 
paulo@0:     * Fix leak of GtNode on incoming connects.
paulo@0: 
paulo@0:     * No longer reply to queries marked with the same GUID.
paulo@0: 
paulo@0:     * Fix bug in GWebCache code where replies got discarded, as well as
paulo@0:       some miscellaneous bugs in GWebCache code, and ban caches that
paulo@0:       fail DNS lookups.
paulo@0: 
paulo@0:     * Updated list of GWebCaches.
paulo@0: 
paulo@0:     * Fix metadata parsing bugs where the metadata was discarded.
paulo@0: 
paulo@0:     * Removed questionably-bad hosts from ban-list.
paulo@0: 
paulo@0:     * Support new Source URL format: Gnutella:?ip=..&port=...
paulo@0: 
paulo@0:     * Timeout push requests to monopolize Chunks less so that Chunks
paulo@0:       will get trapped on inactive Sources less often.
paulo@0: 
paulo@0:     * Shorter connection timeout to monopolize Chunks less.
paulo@0: 
paulo@0: Gnutella 0.0.7:
paulo@0: 
paulo@0:     * Fix a compile error caused by bad prototype in a header file.
paulo@0: 
paulo@0:     * Use a different method for calculating the number of files/total
paulo@0:       bytes shared. Some samples around the median of many pongs are taken
paulo@0:       instead of just using the average of many pongs.
paulo@0: 
paulo@0:     * Ban downloaders for IP addresses in hostiles.txt and incorporate
paulo@0:       ban list from peer guardian.
paulo@0: 
paulo@0: Gnutella 0.0.6:
paulo@0: 
paulo@0:     * Support receive-side decompression of node streams (transmit-side
paulo@0:       compression still unimplemented).
paulo@0: 
paulo@0:     * Source searching re-enabled.
paulo@0: 
paulo@0:     * Preliminary support for parsing XML metadata from packets that
paulo@0:       have them (usually from LimeWire or Shareaza) using libxml. Support
paulo@0:       is disabled by default and needs --with-libxml passed to configure
paulo@0:       to enable.
paulo@0: 
paulo@0:     * Keep track of file sizes/file count statistics from pongs, and
paulo@0:       approximate the number on the network (very haphazardly, I
paulo@0:       might add).
paulo@0: 
paulo@0:     * Fix a potential assert failure when shares are removed.
paulo@0: 
paulo@0:     * Fix bug where malformed incoming connection requests would
paulo@0:       cause CPU polling.
paulo@0: 
paulo@0:     * Incrementally build a larger query-routing table until the fill
paulo@0:       ratio is 1%. Reduces bandwidth used a bit.
paulo@0: 
paulo@0:     * Support active-queueing.
paulo@0: 
paulo@0:     * Fix parsing of bitprint urns.
paulo@0: 
paulo@0: Gnutella 0.0.5:
paulo@0: 
paulo@0:     * Don't reply to our own search requests.
paulo@0: 
paulo@0:     * Fix display of the time to retry when the peer we
paulo@0:       download from supplies Retry-After:
paulo@0: 
paulo@0:     * Fix severe mistake in request parsing that caused almost
paulo@0:       all uploads to fail.
paulo@0: 
paulo@0:     * Remove access.log support, as it has a tendency to consume
paulo@0:       too much disk space when small chunks get requested.
paulo@0: 
paulo@0: Gnutella 0.0.4:
paulo@0: 
paulo@0:     * Download unpausing would crash giftd. Fix it.
paulo@0: 
paulo@0:     * Support requests by hpath (/audio/blah/) as well since its
paulo@0:       not too much extra code to support and useful sometimes.
paulo@0: 
paulo@0:     * Compression was not enabled in configure script, enabled it.
paulo@0: 
paulo@0:     * Firewalled nodes that did searches would accept results from
paulo@0:       nodes with private IPs. Fixed.
paulo@0: 
paulo@0:     * Maintain a banlist of gwebcaches and add any gwebcaches
paulo@0:       that return anything but 200-series responses.
paulo@0: 
paulo@0:     * Fixed Retry-After.
paulo@0: 
paulo@0: Gnutella 0.0.3:
paulo@0: 
paulo@0:     * Add a node cache to store nodes learned from pongs and X-Try-Ultrapeer:
paulo@0:       With this, connecting to the network should be much less ad-hoc. Also,
paulo@0:       returns such nodes in X-Try-Ultrapeer: header for other nodes.
paulo@0: 
paulo@0:     * Access the gwebcaches on demand, rather then when the
paulo@0:       number of nodes is arbitrarily low.
paulo@0: 
paulo@0:     * Use 4-bit QRP patches. Still needs to do incremental updates, though.
paulo@0: 
paulo@0:     * Send "206 Partial Content" replies to partial requests instead of
paulo@0:       "200 OK".
paulo@0: 
paulo@0:     * Support Retry-After: header.
paulo@0: 
paulo@0:     * Basic static stats that assumes the network has no cycles.
paulo@0: 
paulo@0:     * Only send requests by file index, rather than uri-res requests,
paulo@0:       if the previous uri-res request failed or the connection closed
paulo@0:       abruptly. Previously, they were sent randomly. Also, send these
paulo@0:       requests without url encoding, as that is more compatible.
paulo@0: 
paulo@0:     * Update HTTP transfer size after we receive a GIV response, as
paulo@0:       giFT could change the size of a download request while we wait
paulo@0:       for a response from the firewalled servent.
paulo@0: 
paulo@0: Gnutella 0.0.2:
paulo@0: 
paulo@0:     * 0.0.1 would access the gwebcaches excessively due to an oversight
paulo@0:       that the nodes retrieved from them aren't stored because they
paulo@0:       have a vitality of 0. So, this increase in the release number should
paulo@0:       help identifying problem behaviour between releases.
paulo@0: 
paulo@0:       Unfortunately, this adds a new problem in that a completely stale nodes
paulo@0:       file will keep us from connecting. This needs a redesign to access the
paulo@0:       caches if we've exhausted all other options.
paulo@0: 
paulo@0:     * Much improved search timeout system that will detect when
paulo@0:       no more results for a search are likely to come back. Still need to
paulo@0:       check if any results are dropped, though.
paulo@0: 
paulo@0:     * Fix leak of TCPC objects for persistent connections.
paulo@0: 
paulo@0:     * Temporarily disabled locate requests because they need some kind
paulo@0:       of global queue to limit the rate at which they are produced.
paulo@0: 
paulo@0: Gnutella 0.0.1:
paulo@0: 
paulo@0:     * Persistent HTTP support.
paulo@0: 
paulo@0:     * Eliminated most races between download_stop and push downloads.
paulo@0:       There is still the possiblity of the remote end aborting the connection
paulo@0:       before we giFT reissues a download_start request, but that can't be
paulo@0:       fixed without protocol-initiated downloads.
paulo@0: 
paulo@0:     * Submit query-routing table of local shares to ultrapeers.
paulo@0: 
paulo@0:     * Support for using an http proxy to access the gwebcaches (set
paulo@0:       "http/proxy" key in ~/.giFT/Gnutella/Gnutella.conf).
paulo@0: 
paulo@0:     * Testable, but unstable Ultrapeer mode.
paulo@0: 
paulo@0:     * Forgot to report 'Connecting' status when initiating a download.
paulo@0: 
paulo@0:     * Added ChangeLog.
paulo@0: 
paulo@0:     * Use a trie for storing the local shares database to improve
paulo@0:       lookup time. Memory usage still needs investigation.
paulo@0: 
paulo@0: Gnutella 0.0.0:
paulo@0: 
paulo@0:     * Basic support for searching, downloading, and uploading.
