There have been multiple updates to Blockland since the last news steam post.
Here's a catch up post.

r1983

• Fixed crash related to getWords/getFields
• Iconshots/ folder now writable from screenshot functions

r1981

• The fast connection packets introduced in r1972 can now be disabled by setting $pref::Net::FastPackets = 0; or unchecking the "Fast Packets" check box in the network settings tab. Note: this is a server-side setting.
• File downloads will now retry instead of stopping on the "got incorrect hash!" error (note: this is not the issue of downloads freezing in the middle)
• Fast packets will now stop immediately when client goes below the ghosting threshold
• Fast packets will now stop for a given client if their ping goes above 350
• Added missing Parent::onTrustCheckFinished to Brick_Large_Cubes
• Fixed some cases where you could create multiple orphan ghost bricks
• Fixed clicking while tumbling erroneously causing respawn
• Fixed instantly typing "wwwwwww" if you wrench a brick while moving
• Fixed ghost brick moving in the wrong direction while looking straight down

r1973

• Fixed WinXP compatiblity problem from r1972

r1972

• Multiple packets are now sent to ghosting clients on each network tick, reducing ghosting and file download times
• Fixed certain cases of file downloads stopping
• Fixed missing admin checks on some bot_hole server commands
• Fixed case where moving slow moving players can phase through walls

r1966

• Fixed issue where you could travel through a teledoor before it is removed by the build trust check
• Fixed vehicles not burning (both client and server will have to be running r1966)
• Fixed certain timescale/framerate combinations causing the game to freeze
• Fixed coverage issue on ModTer 8x CornerA brick
• Fixed crash when player type has no animations
• You can no longer execute files named "Support_AdminEvents.cs" - this user created script was used in several other add-ons and contained an eval injection vulnerability which would allow an attacker to execute arbitrary script code on the server. Note: this was not a malicious script, it was simply poorly coded and could be exploited to attack the server.

r1958

• Fixed LAA flag regression, should fix some crashes
• Reduced ghost lookup table size by ~10%
• Brick limit replaced by $pref::server::ghostlimit - this setting puts a hard limit on the number of ghosted objects in the game and reduces the size of the ghost lookup tables accordingly.
  • You cannot change the ghost limit while the game is running.
  • The ghost limit can also be set in gamemode.txt. Lower ghost limits are now set for the default game modes, saving significant amounts of memory per player.
  • The label in the custom game gui still says "brick limit" so people might have a clue what it does.
  • The valid values are powers of 2 from 32768 to 1048576, if you set some other value it will automatically round up to next highest power of 2

• $Pref::Server::BrickLimit checks replaced by getBrickLimit() - this function derives the brick limit based on the current ghost limit.
  

r1956

• Reverted ghosting optimization while I figure out what's wrong with it
• Fixed camera relative brick movement with supershift enabled

r1955

• Fixed issue with deleting bricks

r1954

• ParticleData framesPerSec value is now synced to clients
• Removed deprecated aiConnection class
• Removed old, non-functional "storm" features of precipitation object
• Sky object network update size reduced significantly, should fix bad packet when changing environment settings rapidly
• Light list in wrench gui is now sorted alphabetically
• Brick movement is now camera relative when in free cam mode
• Fixed https link parsing in chat
• Partially typed chat messages are now preserved when going from the loading screen to game
• Fixed case where player is stuck in animation on spawn (credit)
• Fixed chat being the wrong size in the loading screen
• Fixed backspace not repeating while playGui is active
• Delete buttons added to save/load bricks GUIs
• Fixed this graphical error on modTer ramp
• Miscellaneous network packing cleanup
• Added ballRadius field to projectileData, used to prevent sports balls from sinking into ground
• Fixed sports balls teleporting up through player when you run over them
• Certain cases of the master server failing will no longer kick players from the game
• Adjusted padding of listclients() console function for 6 digit IDs
• Addressed crash exploit related to NetStringTable - I've attempted to fix the actual bug in the class, rather than detect and filter bad traffic. Hopefully this works.
• Improved error handling on most master server posts/auth queries
• ModTer visible faces fix (credit)
• Client disconnect/CDROP echoes now show player name
• Fixed local connection IPX address echo displaying garbage on Mac
• Fixed screenshot functions being able to write outside of game folder
• Added more sanity checks for brick limit, as people are still somehow setting this to zero
• Made it less trivial to change your client timescale
• Health level of other players is no longer sent over the network
• Random environment button will no longer set transparent ground
• When ghosting, unghosted objects are now prioritized. This is to address slow loading when there are a lot of players/vehicles moving around.
• Increased maximum ghost limit to 1M, what could go wrong
• Increased datablock limit to 8k, that'll be fun to download
• You can now set individual player speeds directly using the following functions
  • setMaxForwardSpeed
  • setMaxBackwardSpeed
  • setMaxSideSpeed
  • setMaxCrouchForwardSpeed
  • setMaxCrouchBackwardSpeed
  • setMaxCrouchSideSpeed

r1931

• Shaders are now automatically enabled for supported video cards
• Removed "-1" chat spam event from lighthouse speedkart map
• Added flood protection to /activateStuff
• Added -serverName and -maxPlayers command line arguments
