Hope this can still help:
With R80.10:
Accelerator Status : on
Accept Templates : enabled
Drop Templates : disabled
NAT Templates : disabled by user
NMR Templates : enabled
NMT Templates : enabled
Accelerator Features : Accounting, NAT, Cryptography, Routing,
HasClock, Templates, Synchronous, IdleDetection,
Sequencing, TcpStateDetect, AutoExpire,
DelayedNotif, TcpStateDetectV2, CPLS, McastRouting,
WireMode, DropTemplates, NatTemplates,
Streaming, MultiFW, AntiSpoofing, Nac,
ViolationStats, AsychronicNotif, ERDOS,
McastRoutingV2, NMR, NMT, NAT64, GTPAcceleration,
SCTPAcceleration
Cryptography Features : Tunnel, UDPEncapsulation, MD5, SHA1, NULL,
3DES, DES, CAST, CAST-40, AES-128, AES-256,
ESP, LinkSelection, DynamicVPN, NatTraversal,
EncRouting, AES-XCBC, SHA256
With R80.20:

Accept Templates : enabled
Drop Templates : disabled
NAT Templates : enabled
The only difference I see is NAT templates (on R80.10 is disabled and on R80.20 Enabled).
