Bold means I need to think about it more

Proto-Nebulonic to Late Proto-Nebulonic

 * /i/, /u/ > /e/, /o/ after an ejective Braana
 * consonant gradation phonemicizes
 * ejectives > aspirated (between vowels)
 * ejectives > non-ejective (everywhere else)
 * plosives are realized aspirated before liquids (and nasals?)
 * apocope of final unstressed vowels (only in some environments: not after /j/ or /u/; which else?)

Late Proto-Nebulonic to Old Nebulonic

 * voiceless unaspirated plosives become glides/lengthen the preceding vowel before consonants other than liquids, and word-finally. /p, b/ > /w/ after /a/, /o/. they lengthen /u/, and remain after /i/ and /e/. /t, d/: lengthen preceding vowel, which then diphthongizes. /k, g/ > /j/ after /a/, /e/. they lengthen /i/, and remain after /o/ and /u/.
 * i > j / _V (other than i or e)
 * /ie, uo/ > /e͡i̯, o͡u̯/
 * LPN /ei/, /ie/, /eː/ > /e͡i̯/
 * LPN /ou/, /uo/, /oː/ > /o͡u̯/
 * LPN /ai/, /ae/ > /a͡i̯/
 * LPN /au/, /ao/ > /a͡u̯/
 * LPN /ea/ > /æ͡a̯/
 * LPN /oa/ > /ɔ͡a̯/
 * syncope (under what circumstances?)
 * accent shift: aspirates attract stress, as do long vowels and diphthongs. what about consonant clusters, voiceless nasals, and voiceless liquids (in which case this shift would occur after the change to voiceless liquids and nasals, or it was still in progress. perhaps the change to voiceless liquids and nasals is from Late Proto-Nebulonic to Old?)? think of which sounds need to be distinguished from others more. compare with Sajem Tan.
 * aspirated plosives become fricatives

Old Nebulonic to Modern Nebulonic

 * /Fr, Fl, rF, lF; Tr, Tl, rT, lT/ > /r̥; l̥/
 * /Fm; Fn/ > /m̥; n̥/
 * /p, t, k/ > /pʰ, tʰ, kʰ/ when not the last sound in a word stressed on the ultima
 * /b, d, g/ > /p, t, k/
 * /ɸ/ > /f/; /θ/ > /s/ (if Old Nebulonic had /θ/)
