Here's all the patch notes since SinaRun release on Steam (and the one right before release which was v1.4.1.3)

For those confused by the 'Update Title' (Bright Sunset for 1.4 for example) it's simply a codename. It change every major version.

Pleasant Sunshine - v1.5.3 (08/02/16 9:48 Eastern Time)

Updated my website address in the footer, credit etc.

Fixed 'Status Bar' ingame font not scaling properly at low resolution
Fixed FPS counter not drawing at the right position at certain resolutions
Fixed Community Interest showing the wrong dev time
Updated missing Polish translations (Thanks Kamil!)

Pleasant Sunshine - v1.5.2 (07/27/16 1:29 Eastern Time)

Known Issues are the same as the previous update

Developer time is now hidden in the bottom bar if there's no dev time on the current map

Fixed misaligned "<" buttons in the level selection menu
Fixed camera not working for a few users who had outdated settings

Pleasant Sunshine - v1.5.1 (07/26/16 9:36 Eastern Time)

Controllers might have issues on OSX and Linux
A few texts are missing in Spanish and Polish translations
Mouse cursor being visible and unlocked when it shouldn't is partly back
Slick Talk lights changes were partly reverted
White Roads bloom changes were partly reverted

That might sound totally insane but I backported the entire game back to Unity 4. Unity 5 actually present too much issues that I don't really want to deal with for the moment at least.

Oh well. I guess I saved 700$. Everything that was broken due to engine changes should be back to normal! (anti-aliasing, colors etc). I must say backporting Elastic Light to Unity 4 was an interesting experience. I don't know if there was an 'intended' solution for this but I ended up writing my own thing. Was fun! In the end Elastic Light look almost the same on both version. (Though I had to find a way to do Height Fog on Unity 4 that didn't break transparent things and anti-aliasing too much)

Re-enabled multiplayer and leaderboards
Removed the link to my Twitter in the menu, some users commented that it felt too mobile game-like and beside I didn't have enough room for this version number
Maximum shadow distance is now 225 (it was pretty destructive to set it higher anyway)
The 'Automatic' settings for resolution is now disabled when in fullscreen (it was intended to be used only in windowed)
Due to the engine changes, Post-AA is re-enabled by default (it look pretty okay in Unity 4. For Post-AA that is!)
Invert Sprint is now disabled by default (Left-over from testing. Sorry)
In Training F3 now allow you to hide the training UI. No-clip is now on F4

LT and RT can now be used to sprint
(A) can now be used to jump

In the future I plan on adding rebinding or at least different layouts but for the time being these two changes should already help a lot!

Fixed additional floating pillars in Slick Talk (specially at the end of the level)
Fixed clipping issues in maps where pillars reached kinda high (Slick Talk, Elevated Highground etc)
Slightly improved performance of some level previews

Golden Opportunity
Made a 'wall' sliiighty larger to make a shortcut easier and more consistent
Moved a pillar to allow for more creative jumps toward the end of the level
Moved a wall slightly out of the way toward the end to allow for a tighter turn

Blue Horse
Reduced shadow opacity to make it easier to see platforms (Thanks GoldenRoxGaming for his video!)

Blast Tendency
Moved a pillar after the first angled pillar (arch thing) jump to make it less frustating (and more consistent)

Elastic Light
Improved performances
Moved many platforms around to better balance the paths

It is now easier to get to the left path and you can now easily commit to the left path from the middle one (where previously you needed to fully commit to the left path at the beginning), in addition it take more time to start with the right path now to better balance the two. Merging to the right one from the center is still possible.

The right path is still not as interesting as the left one even though it's faster but these changes should already contribute toward a better balanced map (and also allow for more creativity from the center path). Further work will be done toward this in the future

Added padding to notes (fix issues where at some low resolution it looked like the text was overflowing)

Fixed various typos in both English and French
Fixed a few crashes related to leaderboards
Fixed missing visual effects in some level previews (Unusual Downtown and Spiritual Era in particular)
Fixed Status Bar ingame not being aligned correctly with the menu at low resolution
Fixed option menu closing when rebinding the pause button
Fixed IP input field label being too small and thus causing two lines for no reason at low resolution
Fixed credits having major encoding issues and not scaling correctly at low resolution
Fixed resolution dialog being mis-aligned at low res (which lead to the scrollbar being hidden)
Fixed camera field of view bugging out in the settings menu when Invert Sprint was enabled (in-game)
Fixed spawn height for the last tutorial teleport
Fixed missing geometry in Community Interest level preview
Fixed Spiritual Era brigtness and bloom issues
Fixed an issue where audio didn't play in the main menu but worked fine in levels
Fixed a missing colon in the Spanish translation
Added missing translation in French

• FIXED the 'Main Menu' button in the pause menu being unclickable on levels that had the leaderboard disabled
  
• Size : 100kb~

• ADDED Steam Achievements! I plan on adding more over the time when I can considering right now the game lack some systems to make 'advanced' achievements work. Also the current icons are low-quality but I'll be getting higher quality ones in the days to come hopefully. Depending on the artists availability
  
• ADDED a Status bar that show various info in game. Currently doesn't show as much as I would like it to. More info will be added in future updates!
  
• ADDED a little box of infos when selecting Levels. It show the level difficulty, your best local time, the dev time and various tags that relate to the levels. Blast Tendency for instance has the 'Sea of Platforms' tag where Unusual Downtown has the 'Slides' tag. This should help players find a level that suit them. Levels can have multiple tags aswell
  
• ADDED more precision to the sensibility setting. The lowest it can be is now 0.05 and it work by 0.05 increments (similar to CS:GO). The highest is still 10
  
• ADDED a button to applicate custom FPS cap without having to click 'Back'
  
• CHANGE Enabled the 'View Full Leaderboard' button in the leaderboards. It open the Steam leaderboards page in your browser
  
• CHANGE Changed volume default value for new install to be 0.4 instead of 0.5. There hasn't been any complaints about default sound volume but I felt like it was too high
  
  UI Visual Changes
  
• CHANGE Made buttons that are not clickable (also known as texts) a bit lighter so it's easier to see they are not clickable. This is for labels and stuff. Not desactivated buttons
  
• CHANGE Updated spacing in the settings menu to better seperate things. The video settings is starting to get a little bit crowded with the new buttons and stuff so I'll see what I can do there in the next update
  
  Map Changes
  
• CHANGE Updated developer time on Golden Opportunity
  
• FIXED Updated spawn height in Unusual Downtown, Blast Tendency, Elevated Highground, Wanderer Hideout, Sweet Sweet Celestial, Golden Opportunity, Slick Talk, Inner Synergy, White Roads (Classic) and Blue Collums (Classic) to be closer to the ground.
  
  This last change should fix a lot of issues people were having with starting levels. Specially in levels such as Elevated Highground and Wanderer Hideout people were often having trouble doing the first jump because they were actually airborne when starting.
  
  Please note that this doesn't mean the 'intended' spawn height is close to the ground. There's still possibilities for maps where you start airborne
  
  Bug Fixes
  
• FIXED the scrollbar in the resolution settings not being placed correctly
  
• FIXED UI overlaying itself in multiplayer on Blue Horse
  
• FIXED a few errors in the Spanish translation (Thanks Rafa!)
  
• FIXED missing texts in the French translation (Thanks myself!)
  
• FIXED more untranslated texts in all translations
  
• FIXED Clear Input on Reset being enabled by default on new installations
  
• FIXED Anti-Aliasing and Shadow Distance not saving correctly on some systems (If you changed these settings before you'll have to change them again)
  
• FIXED various crashes or soft-locks related to leaderboards and lobbies creation
  
• FIXED various crashes related to corrupted settings. This is somewhat temporary as the saving system will completly change at some point
  
• FIXED the password input not being full width (For real this time hopefully!)
  
• FIXED the 'Join Game' button in the Steam UI not working on games that can be joined (Passworded or generally non-joinable lobbies can't be joined with this still)
  
• FIXED invites not working for joinable games in some cases and behaving weirdly (No more forced joining things). Still doesn't work on passworded lobbies and on clients that couldn't/didn't join the Steam Lobby. More work toward will be done at some point
  
  Notes :
  
  This update change how SinaRun understand what levels are. (Hopefully in a more optimised way now) This should in theory not affect players but if you notice any issues don't hesitate to contact me and I'll try to fix it as soon as possible!
  
  Unfortunately due to me being a bit busy with a post-apocalyptic game this update is rather small compared to what was planned at first.
  More content coming in the next updates! Sorry. To fix this, another content update is planned after! But this will be the update that will be up for this first Steam Sales period.
  
  
• Size : 1mb~

• ADDED: Added Spanish translation by community member Rafa! Thanks to him.
  
• FIXED: Fixed the menu disappearing in multiplayer if while selecting a level using the 'Change Server Parameters' menu the player pressed back enough that it looped off or pressed the button too many times in a very quick succession
  
• FIXED: Updated Polish translation for all the text introduced in the 1.4.2 update
  
• FIXED: Fixed the 'No Scores Founds' not being translated. Also changed it to 'Loading...'
  
• FIXED: Fixed not being able to see the new Classic leaderboards in the menu
  
• FIXED: Fixed the main menu not being affected by visual settings
  
• FIXED: Enabled word-wrapping for the main menu (sentences too long will now be on two lines instead of either cutting off or taking too much spaces )
  
• FIXED: Normalized anti-aliasing behavior across levels. As always if you're not a fan of FXAA simply disable 'Post-Antialiasing' in the settings
  
  Map Changes
  
• ADDED: Enabled Leaderboards on Blue Horse
  
• CHANGED: Changed lighting angle a little in Blue Horse to prevent the level being obscured too much
  
  In theory this should be all that needed to be fixed after 1.4.2 release. The next update will be a content one (similar to 1.4.2 hopefully) unless some bugs are found in which case I will fix them ASAP
  
  Size: 1mb~

• FIXED: Fixed FoV sliders in game not working
  
• FIXED: Fixed the walk button not indicating correctly to which key it was binded
  
• FIXED: Fixed walk button not binding correctly in the main menu (worked in game)
  
• FIXED: Fixed being able to play while the menu was on if the player quitted during the animation
  Size: 200kb~

• ADDED: Added a Reset button to the Input settings. This should prevent any issues about non-bindable keys!
  
• ADDED: Added Noclip to the training mode. Simply press F3 to toggle. The controls are the same as in normal mode. WASD to move, Space to go up, Shift to go faster etc. (CTRL to go down)
  
• ADDED: Added a new option to clear all inputs on Reset. Everytime you reset you'll have to press all keys you were holding again. Off by default! (in Game Settings)
  
• CHANGE: Updated Elevated Highground level preview
  
• CHANGE: Reduced the size of the general font used in the menus
  
• CHANGE: Updated many menus with added spacing to make it easier to navigate and re-ordered stuff.
  
• FIXED: Various crashes related to rendering things. Nothing too specific!
  
• FIXED: Left Shift should now be bindable correctly. Pressing Right Shift will bind to Left Shift though
  
• FIXED: Velocity and X Rotation are now saved correctly in training mode (Camera Y rotation work but since it poll the mouse instantly it work for literally 1 frame right now. Will be fixed most likely)
  
• FIXED: Reduced the size of the training UI to avoid it being over the chat in multiplayer in smaller resolution (it wasn't used space anyway)
  
• FIXED: Fixed being able to launch a menu transition while one was already happening
  
• IMPROVED: (very) Slightly improved performances during pauses, resets and level endings
  
  Movement Changes :
  
• ADDED: Pressing CTRL (By default. You can rebind it) now allow you to walk. If you want to go safely somewhere.. This isn't supposed to help you make better times. If holding both Walk and Sprint, sprint will take priority
  
• CHANGE: Air Acceleration is now higher
  
• CHANGE: Sideways speed is now a little bit higher
  
  These two changes should allow for better turning (which in turn should allow for more skips and levels now designed around turns) and improve the experience while still having the linear feel in linear maps (such as Sweet Sweet Celestial or Blast Tendency)
  
  Further changes will be made if needed. Though this should already allow for more creative things and better handling
  
  Map Changes :
  
• CHANGE: Updated developer time for Wanderer Hideout, Sweet Sweet Celestial, Slick Talk, Community Interest and Spiritual Era
  
  Classic Maps Changes :
  
• ADDED: Added leaderboards to Blue Collums, Light City and Dark Abyss
  
• CHANGE: Re-arrangered the menu listing of the Classic Category so that the three leaderboard-enabled levels are first
  
• CHANGE: Slighty reduced fog in Light City
  
  Golden Opportunity :
  
• CHANGE: Rotated and moved a pillar at the beginning of the map to allow for fun map exploration
  
  You might have played in multiplayer with me and I might have promised you that I would do it..
  
  Slick Talk :
  
• ADDED: Added pretty pillars and others decorations to the background of the map. You can't reach them but they look pretty cool! It's mostly because I felt some part of the level were pretty empty of decoration
  
• ADDED: Added a few decorations inside the map aswell but none are really reachable without doing crazy thing. Doesn't affect any shortcuts previously discovered
  
• CHANGE: Lowered light intensity. Apparently not everyone was fan of having their eyes burning
  
• CHANGE: Angled Light differently to make some platforms easier to see
  
• CHANGE: Added more platforms to the beginning of the big turn and changed current one to go with the movement changes and to allow a better experience for beginners
  
• CHANGE: The exterior wall during the turn is now higher to prevent people from thinking that's where they need to go at first
  
• FIXED: Fixed a bug where you would jump higher in multiplayer (only affected Slick Talk)
  
• FIXED: Fixed some platforms that weren't affected by shadows (which was unintentional. Unlike Inner Synergy where the platforms are not affected at the moment)
  
  Overall these changes shouldn't change anything for better players while improving the first experience.
  
  I'm aware this map is painful to play as a beginner due to the big turn in the beginning. Though I hope the turn being painful and somewhat slow is what lead top players to search clever shortcuts around it.
  
  Tutorial Changes :
  
• CHANGE: Rewrote parts of the tutorial to teach the player that holding space make you jump higher, to watch out for the initial acceleration, the fact that R allow to reset during the first tutorial and to make it more obvious that stopping is bad!
  
• CHANGE: Made the first tutorial a lot more safer by making the railing a bit longer, making the bridge wider, adding a little staircase if the player fall on the little railling under and lowered the deathbox so that the player can understand what happened if he were to fall.
  
• FIXED: Fixed the last 'level' of the tutorial not having a death zone
  Hopefully these two changes should lead to a better first experience assuming the player actually do the tutorial.
  
  Multiplayer Changes :
  
• ADDED: When no games are found the game will now ask you if you would like to create one or play in Single Player.
  
• ADDED: Added back button to the level selector. There's always been one in Singleplayer so no reason to not have it in Multiplayer as well
  
• FIXED: You can't load the tutorial in multiplayer using the 'Change Server Parameter' menu anymore (it didn't work anyway. You couldn't see others players nor finish the map)
  
  Chat Changes :
  
• CHANGE: Changed the formatting of messages to make reading easier. It's now "HOUR:MINUTE - NICKNAME: MESSAGE" instead of "HOUR:MINUTE | NICKNAME : MESSAGE" (same as Steam)
  
• CHANGE: The chat font is now slightly smaller to allow for more text to be shown at once
  
• CHANGE: The padding between each line has been reduced a little for the same reason as above
  
• CHANGE: The Chat is now a bit bigger to allow for more.. well you get it.
  
• CHANGE: The limit of character per message is now 155 instead of 100. Will be subject to changes but it should be good for the moment.
  
• CHANGE: The Chat is now a bit more transparent when not focused. A way to hide it completely and making it appear only when message are sent will be added too.
  
• FIXED: The selection color is no longer a weird looking bright orange
  
• Size : 7.4mb

• HOTFIX - It shouldn't be possible to exploit the timer anymore. This is quick hack to make sure it's not exploited. Further changes will be made to prevent any issues. Thanks BOT Fraiser for the report!
  
• CHANGE - The Version Name button in the main menu and pause menu now redirect to the Steam Changelog post
  
• CHANGE - The server browser now indicate properly if a server is password-protected or not (not that you could see it before anyway)
  
• CHANGE - In multiplayer your local time is now shown at all time (where it was written 'NETWORK' before). Keep in mind this is your LOCAL time not the server time
  
• FIXED - Passworded server now work. In both ways. You can now connect to passworded servers and make them
  
• Size : 1mb~

• Fixed multiple issues with the Polish (Polski? Anyway you guys get it. Witcher 3 etc) (Thanks Kamil!)
  
• Fixed multiple untranslatable (and so previously untranslated) words. (Thanks Kamil!)
  
• The game will now load the English translation if it fail to load another (which can happen when translation names are updated (like they were in this update if you used the previously introduced Polish translation))
  
• Added a FPS Counter ingame. You can enable it with F2. It's not terribly precise but it turn red when the FPS are low! (using simple math..) (I recommend using the Steam FPS Counter instead.)
  
• For the main menu it get automatically enabled when you're in the video settings
  
• Fixed the crosshair not getting visually affected by the pause menu
  
• Fixed the crosshair not working on some levels in multiplayer
  
• Fixed the training mode UI not working correctly in multiplayer (this didn't affect every level)
  
• The training mode is now translated (it's still missing lot of functions. Stay tuned!)
  
• Tutorial Changes & Fixes :
  
• Rewrote the tutorial text to imply that stopping is bad! Also updated to make sliding a little bit easier to understand (this only affect English and French as these were the one I wrote)
  
• The tutorial should now reload correctly under any circumstances (without reloading the music or breaking things. In theory)
  
• The tutorial text in the top right corner now hide itself when the tutorial is completed (to allow players who just completed the tutorial to run the map normally without being annoyed by it)
  
• Fixed a major part of the tutorial not having a deathbox (Thanks Kamil!)
  
• Added a little padding at the bottom of the text box
  
• Mise à jour de la version Française :
  
• Grâce aux multiple corrections avec les traductions (deuxième ligne dans le changelog anglais) multiple mots qui n'étaient pas traduit le sont désormais
  
• La vitesse est maintenant en KM/h. Les nombres restent obscène mais bon.
  
• Correction de multiple problèmes d'orthographe dans le tutoriel
  
• Size : 1mb~
