The main fares revision which would normally be scheduled to take place on Sunday 2nd January is very likely to be delayed because the DfT has not yet clarified...
i) the extent of fare rises allowed on National Rail services
ii) the outcomes of discussions regarding future funding of TfL
...and it takes time to implement these changes and update relevant software. 2021's fare rise was delayed until March, and this may happen again in 2022.
On S Stock trains, three tourist announcements are made at all times...
South Kensington: "for the Museums and Royal Albert Hall" Wood Lane: "for Westfield London" Wembley Park: "for Wembley Stadium and Wembley Arena"
...and some are only made between 10am and 4pm...
Aldgate East: "for the Whitechapel Gallery" Barbican: "for the Museum of London" Blackfriars: "for Riverboat services from Blackfriars Pier" Baker Street: "for Madame Tussaud’s" Embankment: "for Riverboat services from Embankment Pier" Hammersmith/High Street Kensington: "for bus services to Olympia London" King's Cross St. Pancras: "for the Royal National Institute of Blind People and the British Library" Olympia: "for Olympia London" Temple: "for Somerset House" Tower Hill: "for the Tower of London, Tower Bridge and Riverboat services from Tower Pier" Westminster: "for Westminster Abbey, the Houses of Parliament and Riverboat services from Westminster Pier"
Lines are electrified with a four-rail Direct Current (DC) system. The configuration and potential of the conductor rails varies across the network. As of 2020, there are three different conductor rail configurations:
a) The original configuration is nominally 630V (voltage), with a −210V centre conductor rail and a +420V outside conductor rail. This is the default configuration wherever deep-level tube trains operate.
b) Beginning in 2016, sections of the sub-surface network were reconfigured to a 750V configuration (−250V and +500V rails). As of 2019, the entire sub-surface network uses this configuration except for Uxbridge to Finchley Road (via Harrow) as 1973 Stock and 1996 Stock (of the Piccadilly and Jubilee lines respectively), share the railway.
c) In areas where London Underground and third rail rolling stock share tracks, the centre conductor rail is electrically connected to the running rails. This still results in a 750V voltage but in a 0V/+750V configuration. Lines configured in this manner include: i) between Gunnersbury and Richmond on the District line ii) between East Putney and Wimbledon on the District line iii) between Queen's Park and Harrow & Wealdstone on the Bakerloo line

...and for the umpteen people who keep emailing TfL wanting to know which postcodes are inside the expanded ULEZ and where the cameras are, the 78511 postcodes are listed here but they won't tell you the camera locations.
