Transmission 3.00 (64-bit)

What's new in this version:

- Allow the RPC server to listen on an IPv6 address
- Change TR_CURL_SSL_VERIFY to TR_CURL_SSL_NO_VERIFY and enable verification by default
- Go back to using hash as base name for resume and torrent files (those stored in configuration directory)
- Handle "fields" argument in "session-get" RPC request; if "fields" array is present in arguments, only return session fields specified; otherwise return all the fields as before
- Limit the number of incorrect authentication attempts in embedded web server to 100 to prevent brute-force attacks
- Set idle seed limit range to 1..40320 (4 weeks tops) in all clients
- Add Peer ID for Xfplay, PicoTorrent, Free Download Manager, Folx, Baidu Netdisk torrent clients
- Announce INT64_MAX as size left if the value is unknown (helps with e.g. Amazon S3 trackers)
- Add TCP_FASTOPEN support (should result in slight speedup)
- Improve ToS handling on IPv6 connections
- Abort handshake if establishing DH shared secret fails (leads to crash)
- Don't switch trackers while announcing (leads to crash)
- Improve completion scripts execution and error handling; add support for .cmd and .bat files on Windows

- Support CIDR-notated blocklists
- Update the resume file before running script
- Make multiscrape limits adaptive
