Two main changes in this update:

Accessibility settings (no shakes, no flashes, no scrolling) in Options → Gameplay.
“Cheat” unlockables (infinite lives, infinite missiles, infinite weapon power). Note that these unlockables come with a hefty score penalty, and while activated they also block specific medals.
Any mid-mission progress as well as all Options menus will be lost.

This is a small update to the Episode which:

Adds a loading screen (to fix the stuttering caused by the initial asset preload). Pro tip: you can still press ESC to skip the loading screen (although of course the loading will still continue in the background, potentially causing stutters for a few seconds).
Adds the "automatic" option for letterboxing (which will stretch up to 20%, then letterbox beyond that).
Due to changes to some internal files, this update will regrettably reset any in-progress mission, and also any Options relating to Graphics/Sound/Controls/etc.

Saving progress fix
This is a very small update that nevertheless fixes a very serious issue: being unable to save your progress if your Steam name started with certain emoji.

EPISODE 2
This is a free major update which introduces the new "Episode" format: a fundamental rework of the game incorporating several significant and far-reaching enhancements:

Remastered graphics. Now in glorious Full HD 1920x1080 (16:9), rather than the original 1280x960 (4:3). Each wave, cutscene, and menu has been individually reviewed and tweaked to account for the new aspect ratio and screen dimensions. And silky-smooth animation up to 150fps (compared to the original's 30fps).
Improved weapons. The weapon roster has been reworked and rebalanced. This is the cumulative result of a large player community effort to make all weapons equally effective and fun to use.
New engine. More display options, more visual effects, better customization for controls, plays nicer with recent versions of Windows.
More languages. This is the result of another player community effort to translate the game to their native language. This project is still ongoing, so expect to see improved translations (or even new languages) over the coming updates.
Built-in seasonal content. Your progress (career stats, unlockables, mission progress) is now unified across all seasons.
Endless mode.
A slew of exciting features have also been back-ported from Chicken Invaders Universe and made available in this update:
https://store.steampowered.com/app/1510460

New weapons
New special weapons
Boosters
6 skill levels (doubled from the original 3)
Custom cuisines
Hot, frozen, electric, massive, and darkness environments
There is even support for exporting your purchase into Chicken Invaders Universe for free! More on that below.
HOW TO PLAY THE UPDATE
The Episode comes as a separate launch option when you click "Play" in your Steam Library.
If you are using a desktop shortcut to launch the game, note that the shortcut Steam creates can only start the game using the default launch option. Sadly, there is no way to launch the Episode directly, however you can force the launch options dialog to be displayed each time the shortcut is clicked.
Right-click on your desktop shortcut, and select "Properties". Replace the URL field with this: steam://launch/449550/dialog
ORIGINAL GAME
The original game format is still available to play. Although the Episode has most of the features of the original (and a lot more besides), there are still some scenarios where you might prefer to play the original:

You like playing using the old mechanics, and the old game balance.
You want to play a two-player game on the same PC.
You want LAN/internet multiplayer functionality. For this, you should export your account to Chicken Invaders Universe (see below for instructions). Even so, the original uses Steam relay servers, which allows it connect even under certain uncommon network scenarios where Chicken Invaders Universe cannot.
You keep track of Steam achievements and leaderboards.
You want to play on Mac or Linux natively.
Purely for familiarity and nostalgia reasons.
HOW TO EXPORT TO CHICKEN INVADERS UNIVERSE (CIU)
