This article is in need of research. You can help out by editing this article or discussing your findings on the talk page. The editor who added this notice elaborates: What about the round generator changed? (So far all that's known is that it affects the rounds used in modes that use a fixed seed)
Bomb Shooter’s base pierce is plenty for the early game but low enough that 1xx crosspath feels too important later, we’re shifting pierce out of crosspath into the base upgrade to alleviate this. Players found the recent increased coverage of 024 recursive too much, but we like the functionality so we’ve tightened the spread for the base xx4 recursive to make 024 about the same as it was before but 004 even tighter. Bomb Blitz has been upgraded to double attack rate from the previous tier. — Update notes
Every Tack Shooter Tier 3 needed a different attack rate boost, so to tidy this up we’ve moved much of that rate to the base tack shooter. Given the bottom path Tack is slightly nerfed from this rate change, it is seeing additional pierce to make an overall buff. Finally Blade Shooter has always visually increased the projectile size considerably but not actually changed this value at all, Blades will now actually be bigger. — Update notes
Players have requested a bonus for the 025 Sniper shrapnel given it’s meant to be a pierce crosspath but struggles on anything non-MOAB, so we’d like to try moving the bonus MOAB damage on 024 shrapnel into base damage instead. — Update notes
Instead of increasing the amount of cash generated, the Navarch will now increase the number of Merchantmen that can receive the benefit. This is an overall increase to cash generation though requiring more of a space investment to fully utilize. — Update notes
As efforts to improve the feeling of top path Buccaneer have gone relatively well, projectile seeking has now been greatly improved for the Bottom path Ace as well. — Update notes
Radial darts: now use Adora's seeking mechanics, allowing them to decelerate to take much tighter turns towards targets and accelerate when targets are directly in front
Plasma Accelerator’s cost is shifting further down to improve upgrade progression. Rocket Storm is gaining a greater bonus to Ceramics for better cleanup breakpoints, and at T5 damage is being moved out from base attack into the ability for a more significant burst of damage when used as currently the ability is underwhelming compared to the main attack at T5. — Update notes
Archmage’s secondary attacks are gaining bonus MOAB damage increases as due to Archmage’s unique mechanics, nerfs building up from Dragon's Breath have also indirectly caused an impact for the Archmage. Prince of Darkness’ buff to other Zombies damage doesn't get much interest, so we’re buffing it. Though the expected dps should be high Magus doesn’t fit well into boss dps windows, so we’re reducing its mana drain rate to increase Metamorphosis duration. — Update notes

“
This is now a ‘part 2/3 temple rework', the actual bonuses have not been the focus of changes this time, instead we have shuffled around the different benefits gained from temple sacrifices to set the stage in balancing out the different categories. [...] We’re interested to hear your feedback in a few weeks, but for a future update we are now considering another step after this is to make temple sacrifices less wide but deeper. One possible option for this that we have discussed is reducing the max number of categories of sacrifice from 3 to 2, but raising the limits that can be invested in a single category to grant the same or more total power from investing in fewer categories. For this to work however each category needs to have a defined use case to pick it over the other categories, we’ve taken one step in this direction with the newly buffed Primary Blades attack dealing massive damage only at close range, and are considering doubling down on the Military category of sacrifices functioning much better at a far range while Magic sits well in the middle. — Update notes
Temple Sacrifices: Category for main attack damage upgrades changed ― Primary → Military
Temple Sacrifices: Category for main attack pierce upgrades changed ― Primary → Magic
Temple Sacrifices: Category for main attack projectile size changed ― Military → Magic
Temple Sacrifices: Upgrade order of additional attacks and upgrades on the Temple's attacks changed. First sacrifice bonus adds a secondary attack, second bonus improves the main attack and further bonuses alternate between adding or improving a secondary attack or boosting the main attack

While we were happy with Arctic Knight’s Ice Jet being a high pierce MOAB layer removal that could with other tower combinations be upgraded to a more effective full-clear, there is not currently enough varied ways of quickly dealing with White Bloon layers, so for a long cooldown based ability this heavy a weakness is too much for now. Bottom path Mermonkey is proving to be very high uptime for the strong support it provides, while still exceptional this is only seeing a light nerf for now. — Update notes
Now reduces the lifespan of Ice Jet projectiles by 33% (undocumented)
Note: This means the maximum travel distance of Ice Jet projectiles is now the same as without the crosspath, since this crosspath increases their projectile speed by 50%
While this won’t change the effective DPS of spike storm at all, the ability will now occur over a slightly longer duration to reduce the effective ‘instapop’ on many targets and give more time to see what’s going on. — Update notes
Primary Expertise is gaining enough damage to allow it to continue to 1 shot MOABs until round 100, but in exchange it will attack slower for an overall power increase. — Update notes
Now that Ultraboost has an initial cooldown we are again allowing it to be used between rounds. Middle crosspath feels too good for Bloontraps because of the massive quality of life it brings, so we’re pushing the DPS more for top crosspath by allowing Double Gun to also double the projectiles of Sentries. The expensive XXL Trap's cash generation comes in too late given Bloontraps fall off as an income generator in the late game, so we’re reducing the upgrade cost and increasing the cash generation that it brings. — Update notes
Max power Great White drags in MOAB's too quickly which actually causes it to thrash less from this and overall perform worse, so a minimum drag time has been set. Megalodon's 'not 1 shotting' damage feels too low compared to when it is able to 1shot, so we’re increasing this damage. — Update notes
Ezili’s first bonus against MOABs is swapping forward to an earlier level so she can do something in time for the first MOAB on round 40. — Update notes

While working on the new Battle Cat power we concluded a number of existing powers that haven’t had love since launch are no longer living up to a worthy level of power in the modern state of Bloons, so we’ve made modifications to some of these to make them more useful for the cost. In particular, we felt like there were very few times to ever use MOAB Mines over Super Monkey Storms so these have been given a considerably more powerful single target use case to use in situations in which Super Monkey Storm would normally struggle. — Version 46.0 update notes
The Paragon formula applying a flat +100p to any attacks has been limiting our design in building low-pierce balanced attacks for Paragon upgrades, in particular we could not embody the design of the Tack Shooter’s 1 pierce meteor attack due to this, so we have lowered this flat pierce bonus for further review. — Update notes
