From 1.18 to 1.19

This is the important parts (i.e. not to do with DromEd) of the patch notes for 1.19, which themselves claim to be just "a small sample" of the changes.

Renderer

Added windowed mode
Added single display mode option - no resolution change between menus and game
Added ingame support for all common resolutions, including widescreen
Added support for 32-bit color
Textures can now be automatically promoted to 32-bit, improving quality and effectively eliminating the palette limit
Added UI framerate cap option to avoid GPU fan spinning up in UI
Added DDS/PNG image support
Added full 24/32-bit TGA/BMP image support
Increased the maximum number of frames allowed in animated textures from 20 to 99, and increased the allowable filename length for animated textures (before the 
 underscore) to support more than 7
Animated texture rate can now be specified via a material file for that texture
Fixed a bug where Transparency property didn't (correctly) apply on objects that contain transparent polys

General

Added mousewheel support to options menu
Added the ability to detach from ladders by crouching
Improved mantling a bit and added optional new mantling algorithm with lower failure rate
Lowered player crouch height by a tiny fraction so he's less likely to get stuck on 4 unit tall spaces
AIs now breathe from their head instead of their stomachs. They will no longer drown when up to their waist in water.
Fixed pickpocket count bug that would always show 1 more maximum pickpocket than there actually was.

Replaced video player lib with an FFMpeg based one to play cutscenes. LGVid.ax or other codecs are no longer required
Option to use OpenAL (if available) instead of DirectSound. Includes support for audio effects in Windows 7 without an EAX-enabled driver (e.g. ALchemy)
Added "head_bob" config var to control amount of head bob
Fixed player ground contact tracking when walking off an object (caused footstep sounds to get "stuck" on previous material)
Fixed sound cap per schema type bug and upped max sound channels to 48
Changed screenshot output format to BMP and also added support for PNG screenshots
Changed mouselook sensitivity to be resolution independent
Added check to avoid trying to open files with reserved system name like com ports
Added better support for binding actions to the mouse wheel (can bind wheel up and wheel down as separate actions, with modifier key support)
Fixed star rendering
Added "log_player_pos" command that dumps current player pos to log file (when enabled)
Fixed a bug which limited number of sound channels to 16 even if more were selected
Fixed a bug that sometimes caused doors to float away into infinity
Fixed (or at least greatly improved) a bug with edge triggered OBBs sometimes failing to detect collision (in particular for slow moving objects)
Fixed framerate dependent speed issue for camvators/moving terrain (with collision type: none)
Added "fixed_star_size" option for resolution independent star size
Fixed some bugs when attaching to a ladder from water.
AIs who are facing very close to a wall will no longer turn to face south when the game begins
Health bar drawing adjusted in widescreen
Added option to fix arm rendering
Added AA to rendering of loadout screen items
Added "Blocks frobs" property, allowing objects to block frobs of objects behind them (e.g. to stop frobbing items through safe doors)
Added option to left-align map notes text
Made navigation of map/objectives screen a little bit more in-game friendly (screen can also be closed with space, arrow key navigation and return to switch map/obj)

Later changes

It doesn't seem there were any more critical changes from 1.19 to 1.23 except maybe for the addition of mouse button 4 and 5 support, but here is the reference if you want to see for yourself: Thread on ttlg.com forums. Make sure either Steam or GOG are offering the version you mean to run and don't do any extra patching yourself, otherwise it doesn't count as official!
