Use minimum MTU for IPv6 session confirmed to avoid PMTU issues
Set default MTU for known IPv6 tunnel brokers
Check for s mismatch in session confirmed RI
Don't put DateTime block after Termination block
Fix first message failed check
Log sent data packet size
Log tweaks

was treating them as acks

not simply when a new file is downloaded

Fix setting local IPv6 MTU when firewalled
Fix publishing MTU when firewalled or hidden
Save local MTU when changing addresses, not when publishing
Add SSU2 MTU methods (no mod 16 required)
Allow MTU up to 1500 for SSU2 transport style
Disable SSU2 at startup if local MTU too low

Caused SusiDNS and addressbook to be in a different context
addressbook config would be stored in base dir
and subscriptions would not load because it couldn't find i2ptunnel

Enable relay
Set session created token to 0 as per spec
Log tweaks

Don't send SSU1 relay request to SSU2-connected introducers
and vice versa
Log tweaks

per spec, Alice hash not included in msg 1/2 sig
Add sig checks of msgs 1/3 at Bob
Fix checking of 'B' cap in peer selection

cancel DHT cleaner and explorer on stop

and causing tracker error on initial announce

Strip % suffixes from addresses before comparing
Fix HTTPMUSocket.getLocalAddress() to return the correct bound address
Throw exception on multicast socket bind failures, don't attempt
further operations on failed sockets
Add toString() to sockets for debugging
Log tweaks

to avoid conflict in applications linking to apache jars
As requested by 'mesh' project
Remove with-libhttpclient-java build option
No known external uses other than obsolete i2pcontrol plugin

Change size/ip/port fields to match changes in proposal 159

Don't set our RI loaded from disk if too old
Rekeying was prevented by previous checkin,
but this fixes root cause

Revert related parts of "Prep for fragmented RI",
we are now fragmenting Session Confirmed instead.
Fragment and send multiple Session Confirmed packets if required
Reassemble Session Confirmed packets

Don't process ack block identical to previous received
Log tweaks
bump -12

Fix IES2 not being removed from pending after complete
Don't send DSM after handshake
Validate conn ID before pkt type for data pkts
More log tweaks

SSU: Increase min pending establish states limit (unless slow)
Reduce IB establish timeout to 15s
Log pending inbound establish states when limit exceeded
Log tweaks to add establish state lifetime
Bump -11

even if they would fit in the MTU uncompressed,
to save bandwidth and room for other blocks

Fix length calculation to see if new token block will fit in session confirmed
Extend timeout after sending retry
Fix retx timer for sess req after sending token req
Remove dup call to confirmedPacketsSent()
Cancel ack timer when sending acks
Include intro key in firewalled addresses too
Use SSU2 version of ping packet for SSU2 peers
Reduce max padding
Log tweaks

so it doesn't null out the contained message.
Required for SSU2.
Unrelated TunnelDispatcher cleanup done while trying to find the problem.

Only affects NTCP for now.
This bug had little impact when both transports were enabled,
but significantly harmed connectivity and tunnel building for NTCP2-only.
Decrease unreachable cache time in testnet
Make cache cleaner a little more efficient

Increase credit if family sig is verified
Speed up analysis by only looping through RIs once
Add link to all family members
Add SUNYSB certificate
bump -2
